Home / I-Opener Areas / I-Opener Technical Stuff What are people using for ATAPI connectors to their CD-ROMs? What connectors to interface with the KX15-50KLD?

What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) KneuB_2 Profile | Email It has been awhile since anyone posted on this subject and unfortunately all of the prior posts talk about the problem of CD-Rom connectors but no-one ever gave a solution. I assume that by now a solution has been found since Toshiba, Teac, and God knows how many others use the same connector pair (KX15-50KLD with/to a KX14-50???). My questions are; What connectors have people been using to connect to these type of CD-ROMs? And most importantly From where can they be purchased? Please dont say Toshiba, JAE.com or PCsupport.com or list any of their 1-800 nummbers as I have just spent lunch hours for the last two months trying to track down a connector through those means (and all the local shops in the greater seattle area) and I can honestly say that of all the people I've talked to and e-mailed regarding this quest, none of them have rated high enough in the catagory of usefullness to a customer to endanger the title held by "teets on a boar". 10-22-2000 18:02:37

Am I asking the wrong people here? (modified 0 times) KneuB_2 Profile | Email Do I take it from the boards silence that nobody has succeeded at using a CD-Rom with a "standard" ATAPI connector. This is very sad. 10-23-2000 23:56:39

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) ckbone Profile Don't be too sad.....Using a standard cdrom with an external power supply has been done by several people. You can use a std 2.5/3.5 adaptor setup or you can get a fancy setup from Badflash. My own cdrom setup is a laptop model (Toshiba XM1402B) it uses a standard 44 pin connection.....I had Badflash make me an extra long 44 pin cable, and I have both the hard drive and cdrom mounted externally. If you search around, many laptop cdroms use this 44 pin connection, which is relatively easy to hook up. My standard power supply drives both the hard drive and cdrom with no problems. I doubt if you could do it like this if you were using a modified CPU setup....the power supply is probably too small. The easy availability of external USB and parallel port cdroms has made this a relatively rare modification. 10-24-2000 03:18:53

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) Glitch Profile KneuB_2, I've been looking for these connectors also. The only thing that I've found that "looks" like the connector is a Hirose FX8. However this connector is too small. I've also searched manufactuers sites like AMP & Molex with no luck. It shouldn't be this hard to identify the connector :(. Have you tried calling any of the big connector manufacturers? My only other thought is to remove the ATAPI connector from the drive and replace it with something which can be readily adapted to the 44 pin cable. The trace spacing on my drive is 0.050". I haven't found a suitable connector yet. I'll post here if I make any progress. Glitch 10-24-2000 09:52:01

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) KneuB_2 Profile | Email Glitch; The only connector manufacturer that I've attempted to contact via the telephone instead of e-mail is the Portland branch of JAE. So far we are setting new records for phone tag. I agree whole heartedly with your perspective, for an Industry "Standard" it should'nt be this hard :( Somebody someplace has got to carry something. I'll keep looking and posting, it has to be out there somewhere! KneuB On D Blk 10-24-2000 17:55:12

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) mp3boombox Profile | Email I'v got a WORKING multi port in my iopener i dont know if any of you have read my messages but check this one. In this a few of my messages tell about how i put a CDROM into my io's standerd base unit. It's now a fully working multi port for my IO http://www.linux-hacker.net/cgi-bin/UltraBoard/UltraBoard.pl?Action=ShowPost&Board=technical&Post=950&Idle=0&Sort=0&Order=Descend&Page=4&Session=mp3boombox.96536404546619 10-25-2000 17:31:26

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) anty Profile To connect my HD, I used a 44-pin connector and a 40 pin connector. I used 6" of 40-pin and 44-pin ribbon cable and then just spliced each wire together alternately. This way I can connect any 40-pin device to the io including cd-roms, hd's, etc. It's much cheaper than getting a 44-pin cd-rom. I bought the connectors from Archtech. They're the only place I could get 40 and 44 pin connectors as well as ribbon cables. They're at http://www.archtech.net They usually take business accnt's but will do it for a single customer too. I also have a hack page at http://www.engr.uconn.edu/~ameer good luck. 10-27-2000 09:51:17

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) Wild_Pencil Profile | Email I got adapters with the HP slimline CD-ROM drives I bought. These are the same drives recommended by http://www.mainstreettech.com and, oddly enough, are the cheapest notebook cdrom drives I could find. *shrug* 11-06-2000 00:11:52

I found Samples (modified 0 times) KneuB_2 Profile | Email OK .... I found samples (see the 8th post. I have also found the IDE pinout and the ATAPI pinout with exception that I can't identify which pin is pin 1, 2, 3,....etc. on the ATAPI connector. I'm trying to draw up a simple PCB adapter with the ATAPI connector on one side and a header on the other. I could sure use some help identifying the pins here. 04-25-2001 23:35:23

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) BigDog Profile | Email Badflash mentioned sometime ago he was working or going to work on a converter, I bought a cdrom off ebay that came with a the 50 pin to 40 pin IDE with audio hookups and power supply connections, I was able to rig it up to one of my IO's using a 40 to 44 pin ide converter. I was working on a converter, I have several small PCB's with the JAE 50 pin connecter that mate with the connecters found on the slim CDroms, I was going to trace the pinouts and attach a 44 IDC cable but got distracted when I broke down and bought a USB cdrom drive. I also have all the "standard" pinouts documented and converted in a table from the JAE 50 pin connecter to 44 pin IDC connecter, I won't swear they are accurate but I feel the are pretty good. Drop me an email if you are interested in the documentation or the PCB boards. 04-26-2001 09:11:10

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) parasyght Profile | Email i bought a jae to 50pin adapter, 44 + audio and m/s jumper. I payed about 30 dollars for it, expensive little ####. I made a cable to connect my slim dvd and hard drive but was only able to get one properly recognized at a time. Really pissed me off. I set it aside for now, i have an lcd project to work on, but you have to call them, 1-714-990-9324, its in southern california, they will know what your looking for, they only deal with optical drives. http://www.phethean.com talk to them, its your best bet. 04-26-2001 11:58:57

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) BigDog Profile | Email parasyght My V5 wouldn't recongnize but one IDE device at a time, I had to disable the Sansdisk to order for the hard drive and cdrom to function. I had to lift pins 37 & 39 from the Sansdisk controller, I plan to install a pair of dip switches to allow enabling the 16mb Sansdisk drive, but I never got around to it since so far I have had no need for the HUGE storage space it provides!! 04-26-2001 14:50:26

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) parasyght Profile | Email is the controller the square one with the pins on all 4 sides? 04-26-2001 16:46:43

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) BigDog Profile | Email Yes, I believe so, I have the covers on my IO's right now, Yes, I have the data sheet right here... The TQFP controller is the 100 pin chip with pins on all four side, the TSOP memory chip only has pins on two sides. Pins 37 & 39 are on the side facing the IDE cable connection, I believe the board has tick marks on every tenth pin (or it may be five) you need a fine top iron and a fine tip edge like a dental pick. The pins are small, be careful! There was a post awhile back about someone who used a Dremel to cut the chip off, but lifting pins 37 (CE1) & 39 (CE2) you disable the chip in a manner that Sansdisk intended and if you are careful, you can enable later if you need. Here is an old post regarding disabling the chip: http://www.linux-hacker.net/cgi-bin/UltraBoard/UltraBoard.pl?Action=ShowPost&Board=verytech&Post=87&Idle=0&Sort=0&Order=Descend&Page=0&Session=bigdog.98833531097465 04-26-2001 18:55:00

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) Greenspark Profile It's been discussed before, but on my V5 I simply disabled the secondary IDE and the CD-ROM was detected. It wasn't detected in the "normal" master/slave detection activity, but it showed up right after that. Strange, but it works. 04-27-2001 09:13:23

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) parasyght Profile | Email does it say something like" found: cd-rom", after the primary and slave devices have been detected? Mine did thise, but only when the hard drive want connected. 04-27-2001 10:53:09

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) Greenspark Profile Yes, that's what it did. Harddisk was set to master, CD set to slave, it all worked in Win98. 04-27-2001 12:42:06

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) parasyght Profile | Email since im using the jae to 50 pin adapter, i dont have the right slave/master jumpers on the back of the dvd drive. Ive tried everything, its time to lift some pins.Unless your using th jae to 50 adapter, then you would know which pins i need to jumper, or if it really has them. 04-27-2001 17:00:33

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) BigDog Profile | Email Try to find the technical documentation for the cdrom you are using, most vendors use pin 47 on the JAE connecter as "device config", grounding this pin to ground on pin 48 may switch the cdrom to slave. I have a Toshiba XM-1502-B and a Toshisba XM-1902B which both select themselves as slave if there is a master device on the IDE bus. 04-27-2001 19:13:38

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) BigDog Profile | Email I just got off the phone with the sales department at http://www.phethean.com/ about purchasing a fairly large quantity of the JAE50 to 44 pin IDE adapters for the notebook CDROM drives. I am going to order a sample and be sure it is the correct type. The only thing about this adapter is that apparently it does not have an audio connecter for the CDROM audio. If this adapter is the correct one, it can be used to run practicaly all notebook CDROM's and CDROM-RW drives that are available on the i-Opener IDE 44pin interface. I can get a fairly decent price if we go in on a group buy, the adapter will cost about $17.00 which includes shipping, If I buy all they have, the individual cost will go down to about $13.00 including shipping. If you want to buy this adapter directly from them, it will cost $25 and they do not accept credit cards. Is anyone interested in this adapter? When I get my sample, I will post the results. Post a reply if you are interested in this. 04-30-2001 13:47:01

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) dan67sf Profile BigDog I would be interested in 1, let me know of your test results and the cost including shipping. thanks 05-03-2001 08:34:12

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) 02U2 Profile About a year ago I found one of these adapter/connectors dumpster diving at "Arbor computers" here in Seattle. It was in a bag with a new OEM Win98 CD and Certificate, Slimline desktop computer manual, a 4 GB IBM 3.5" Hardrive and a few other odds and ends. At that time I was not sure what the adapter was for but I tossed it in with my vast collection of (My friends call it junk) Kool stuff. It definately is an 3.5" IDE to Atapi interface. There is no part# on it or MFG but it looks like it was made overseas. Has the audio out connector on it. Has 2 mounting holes for screws to attach to the back of the CD-ROM drive. I wish there was more info on it for you guys but thats it. I did fit check it with a recent 24x CD-rom drive and worked fine. BTW Arbor/Micro supply computers was one of my best source of free thrown away OEM parts. About 90% of the stuff was perfectly OK. They went out of business...Go figure, I sure miss them... 05-06-2001 17:49:43

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) BigDog Profile | Email I got the samples in from http://www.phethean.com (aren't samples free ?? these weren't) and they are 50 pin 2mm to the JAE connecter adapters and they have a shroud around the pins (plastic frame around the outside) the plastic might need to be cut down and the pins traced to see if it will work, I suspect that they are staight through since the JAE connecter has 50 pins. and I don't know if that will work with a 44 pin IDE (I stand corrected - It would appear that parasyght is using them). parasyght What pins are you using in the back of the 50 pin adapter to your 44 pin IDE ?? I am not sure if I can coordinate a group buy if only a few are enterested in buying these, I was told they had about 120 in stock and they would cost $10 each if I bought all 120 of them or if I bought 30 the price would go up to $13 each. As it stands now you can "buy" samples for $20 each and they charge $5 for shipping. They do not accept credit cards, I had send them a personal check to pay for mine, (my pair cost me $45) I believe Badflash is going to have this type of cdrom adapters sometime. As it stands now http://www.phethean.com has them and they cost $20 each plus $5.00 for shipping. Is anyone interested in taking this over ?? 05-16-2001 13:42:47

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) parasyght Profile | Email Im not at home right now but i can tell you ive had a hard time getting my cdrom recognized as a slave device. Ive been told that the i have to the disable the sandisk to get it to work right, but havent gotten around to it yet. The cdrom works fine when it placed as a master, but the my hd wont work right. I let you know what pins im using when i get home, but i can tell you that it does work. If you really want to get people interested, you need to figure how how to fit the damn thing in the case. Ive spent hours trying to do just that with no luck. I found one place it would fit if we can remove to of the electrolytic capacitors on the top left close to the left side of the ide header. 05-16-2001 13:54:53

An ATAPI 2 IDE PCB adapter (modified 0 times) KneuB_2 Profile | Email I've been using my lunch hours for quite some time now trying to figure out a compact routing for an ATAPI to IDE (laptop) adapter and I think I've got one albeit with some questions still attached. GROUND I used the CD-ROM pinouts from Toshiba and the IDE pinouts from SciElectronics FAQ along with BigDog's spreadsheet identifying the pin to pin arrangement. The first issue that I have is that the pinout from Toshiba's site specifies which pins are "digital ground" vs "ground" and neither of the other sources identifies digital ground. So.…I arbitrarily separated out ground pins for digital, does it really matter. POWER I laid out the traces using the guidelines from apcircuits with .008 inch minimums for both trace and spaces. That doesn't address the issue of power. I found this calculator for trace width requirements based on how much power the trace will carry but I haven't found any information on power requirements for the individual pins to/from a laptop CD-ROM. So again I arbitrarily fattened up the power and ground traces to .016 inches. VIAs When laying out the VIA's I couldn't find any guidelines for how much of a (for lack of a better term) flange I should leave at the ends of the VIA's for soldering purposes etc. How small is the bottom edge of practical? SOUND I couldn't figure out what to do with the four pins off the ATAPI connector for the sound, so I routed them to a 4-pin header (2mm spacing). If that was the right thing to do with them it really needs a smaller connector and I've struck out in that department as well, any suggestions on a smaller connector would be appreciated. BTW: the links to free samples of the ATAPI connector (click on the sales link) and the Header are listed in this boards Free Sample thread. (OK the header isn't listed but I'll put it there soon, and yes I did get a free sample of the ATAPI connector….not that I can solder that tiny stuff yet) SET-UP Fees The biggest issue is getting it produced, I hadn't found any way past the $1500 to $2000 set-up fees the pop out of the fine print at every prototype board shop I can found until r-fl-z suggested I take another look at expresspcb.com. I did and as long as I'm willing to forgo the green protective layer and silkscreen I would end up with about 30 (10 per board X 3 boards) of these adapters (without the soldered on components). I do not have any interest in trying to produce and re-sell these things. However, if anyone is interested in going in on this with me to justify one run please drop me an e-mail. Also if any one is interested in taking this over for what ever reason (Codeman, Badflash; are you guys reading this) please drop me an e-mail. HIND SIGHT I'm converting this board over to the expresspcb software (the original was e-mailed to a few people in pdf format for comment) and in looking the board over I can now see a way to re-route a couple lines and add one via so as to get access to 3 ground pins on the IDE header that I did not connect to the ATAPI pads, but I don't see it as necessary. If I've made an error in that assumption please speak up. 07-26-2001 12:30:34

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 1 times) Wild_Pencil Profile | Email .. without the soldered on headers? Ouch. I don't think my soldering skills could manage to mount those tiny JAE-50 headers without burning up the whole thing. Any suggestions on tools or equipment for doing this, if it becomes a do-it-yourself solder kit? Also.. if you could route the last 4 pins (audio signals) to a separate area where I could either solder my own 4x1 header or solder directly to the connector, that would be ideal. Then it's just a matter of connecting these to the CD-Audio input pins on the Yamaha chip. Sweet. -WP 07-26-2001 13:24:08

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) dvfagan Profile | Email NewB2, I have the software for generating the PCB files. Fatten up the power and ground traces as big as you can. They are capacitors if they are on adjacent layers. I can help if you need help. I deal with Accutrace in San Jose. They photoplot and turn small jobs for about 1K. 07-26-2001 13:56:44

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) dvfagan Profile | Email KnewB2, You really need a solder mask for hand soldering metric connectors. Don't let anyone talk you out of it. How many layers is your current design? 07-26-2001 15:00:18

ATAPI Adapter info (modified 0 times) KneuB_2 Profile | Email The sound traces have been routed to a 4 X 1 through hole header (2mm spacing) but it is really tight and doesn't really meet edge clearances. Is there a smaller connector that you know of? I can fatten the ground and power a little bit, they are on opposing layers but offset, I'll see how far I can go. The board is two sided .42 X 1.72 inches. I would love to have the solder mask but that $1000 price tag you just mentioned is a bit steep, any other options. 07-26-2001 16:02:56

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) dvfagan Profile | Email I am using a round pin .020 dia 2 mm. header. Using nominal clearances, you can put this in a pad .034 outside and .026 inside. This would leave pretty good clearances. Your boards are quite small and that increases your cost slightly. Accutrace will laser cut multiple cards from one set of gerbers if you leave .300 spacing between the images. This will save you money. I would suggest a step and repeat of 20 cut out of one set of gerbers. The price I referenced included 5 pieces of 40 sq. in. two sided board with solder mask and silk screen and included photoplotting. You can call them at 800/600-6611. 07-26-2001 16:16:12

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) dvfagan Profile | Email I know that PCBs are expensive, but the pitch of the connectors involved precludes exposing FR4 on the roof of your car in the sun. I have a gerber tool that will step the images and would be glad to do it for you. The other cost driver you have is hole count. They run up the laser drill machine time. 07-26-2001 16:23:43

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) KneuB_2 Profile | Email OK .... I may have found a workable solution to the cost issue. OLiMeX.com will panelize approximately 28 piecies on a single double sided board with plated thru holes, solder mask, silk screen, depanelize and fully "ASSEMBLE" for approximatly $130 if we supply the ATAPI connectors and headers (or pins). I'm tweaking the design to include a practicle 1 X 4 header for the sound pins. With that in mind, If I organized a group buy is there enough interested parties willing to acquire the sample (or otherwise) connectors and share the cost to make this feasible? NOTE: I'm tweaking the design and the specific ATAPI connector may not be the one I identified earlier in this thread so don't order samples yet, I'll solidify the design specifics and post them as soon as I can. My purpose for this post is to sound out the members here for support. dvfagan I've got a netlist 95% complete now, are you still available? 09-05-2001 16:55:20

RE:What are people using for ATAPI connectors to their CD-ROMs? (modified 0 times) dvfagan Profile | Email I'm available. Send me the netlist and connectors to: DV Fagan 1565 Inverness Ct Boulder City, NV 89005 It should take two days to generate the Top, Bottom, Solder Mask and Silk Screen Gerbers and Drill Tape. All I want is three bare cards. The step and repeat reference looks like a good idea. 09-10-2001 17:18:08
