Adding Floppy, video, serial connectors - is it possible

New MessageAdding Floppy, video, serial connectors - is it possible (modified 0 times) Dag2000
Profile | Email
Seeing as how 340 Webplayers are about to be unleashed on hackers through the coop, and more people will be considering riskier modifications, I thought I might pose some ideas I just started considering myself. I'm getting a second WP through the coop for myself and will be willing to consider risking hardware alterations on the spare.

I went through my box of old cards and came up with a floppy controller card, an old video card and a serial port connector (there was lots of other crap too, but these are the things that seemed useful for the webplayer).

I know that there are locations on the webplayer MB for a floppy cable connector, a VGA video out connector and an as yet unknown 10-pin connection. Can anyone discern whether the MB is populated for these connections. I think I recall someone saying the floppy controller was populated, but simply lacking a connector. If that's the case I'd love to solder the connector from my old controller card onto the webplayer MB and connect a floppy. While there is a location where one could solder on a VGA connector, it looks to me like there aren't any traces connected to these solder points and thus adding a VGA connector would be pointless. Can anyone offer an educated opinion on that?

As to the unknown 10-pin connector location, is it possible this is for a serial port using a non-standard MB connection? My serial port has 10 pins, a 10 wire cable and a five over five connector. What I am suggesting is that the MB is physically laid out for the same kind of serial port using a straight (in a line) connector to the MB. If this is so the five over five connector could be amputated and the wire ends directly soldered to the MB or a frankenstein connector could be created, No?

Can anyone venture an informed opinion as to whether this might be a serial port connector location and if what I've suggested would be possible.

I know it is easier to ask the questions than to find the answers but I've got no practical soldering or electrical experience. If someone can figure this out, it could be open a whole new level of functionality for the webplayer. A floppy would mean simple transfer of word processing and similar files. While I'm not particularly interested in the video out, I'm sure some people would love it. The serial connector would allow a whole host of add-ons not currently possible. I have in mind things like a touch screen add-on that requires a serial port (saw it somewhere for about $180) and the X-10 mouse remote which would make in-car uses much more interesting.

Do these ideas fire anyone's juices?

Another thought/question:

What about the compact flash adapter? Does this just require a connecter be soldered in? It would make a great way to provide extensive storage for digital cams while travelling: just download 'em off the card to the WP in your hotel room for temporary storage till you get home and can move em to your desktop.
Also, are there any other connectors provided for but not installed on the MB? My goal is to explore all the possibilities for these nifty little boxes.

I have a webplayer with the floppy port soldered on, the 10 pin and port 80 too. The FDC does work, it is
for a laptop floppy drive though, I dunno if a normal one would work...

I don't feel like opening up my WP right now but, reviewing my pics, I had a couple more questions:

Can the IRDA be populated? Can anyone think palm pilot? Or even just for an IRDA printer connection.

M_firmature: Am I correct the the serial port has a connector installed? It looks as if a pin or two is missing, is that a problem? What is port 80 used for? Do you know what the ten pin connector is for? I am assuming you installed these connectors, right? What parts did you use? Where did you get them? Is there a difference between a notebook Floppy and a desktop? what? Do you know of a source for notebook FDD's? Do you want to be a millionaire? Is that your final answer? Have I asked enough questions?

I've seen minipci 10/100 ethernet cards - the question would be WHERE DOES THE ETHERNET PLUG IN? Card doesn't look like it has a port, so it must map to the MB - and the WebPlayer has no such port (at least not one that is enabled)

Any ideas?

Heh, The board that has the connectors was one of the first webplayers out there, my neighbor gave it to me. I did not install any of these ports. Let me look in some electronics books and see if I can give you a distributor... As for the serial I think that it will work fine, it just looks a little small to me and I do not have any old at serial ports to try and hook it up to. The floppy port works fine, just turn it on in the bios. The difference between a laptop floppy drive is the size and connector, the connector on my board is a ribbon cable type not just pins sticking up. I got this drive out of my dell cpi or cpx. These are readly available on ebay for less than 30 dollars just do a search for "dell cpi floppy" or "dell cpx floppy". The problem i had is the wire is less than 3" long, way to short to even turn the drive around while connected, If anyone knows where or how to get this wire in length then this could work. I will take some picts In a day or two because a friend has that webplayer right now.

You could try "sharing" the printer if you have a reqular pc on the same network as the Webplayer.

I am a bit befuddled. I keep hearing about this 10 Pin mystery plug on the board. I don't recall seeing this? Am I overlooking something? Or do you all mean the 12 pin com connection?

You are overlooking something. For one thing it isn't a connector. It is a spot near the rear (away from the screen) side of the MB where a connector could be soldered. It is next to the spot for the VGA connector. Look at the pics on my site or one of the others and you'll find it.

Well, that makes a bit more sense... :)

Has anyone got the 12 pin com port to work for a serial device? I have made a plug for it using a simple 44pin IDE ribbon and my trusty versapak wizard (wireless dremal clone). I cut out 2 - 12 pin plugs out of one end of the 44pin cable (leaving a 12 wire ribbon for each) the other end can be soldered onto a standard serial plug if you know the wires to use and the correct pinout.

Has anyone else been playing with this connector? Anyone measured the voltages and traced the pinout? If so, please let us know.. Save me a bit of time :)

OK, after a quick search on Google, this is what I found:

The 10 pin is a serial connection. Info at:
http://www.fic.com.tw/techsupport/faq/faqsparts.htm
and:
http://www.mypchelpmate.com/h5.html
and:
http://www.geocities.com/TheTropics/Shores/2250/pinout.html#10
and:
http://www.randomc.com/~dperr/pcpinout.txt

Next, the port 80 is for MOBO diagnostics, per:
http://www.rentron.com/BIOS_Stamp.htm
(also includes info on making the diagnostic card that plugs into said port)

Finally, I don't have my WP with me, nor is it apart at the moment, so I've no idea what the 12 pin port is labeled as. I can't quite make out the words on the mobo picture at:
http://www.gothamgraphic.com/virgin/pictures/vwp-MB-Top-close_IMG.gif
Anyone have a better picture, or want to tell me what it says? Otherwise, as near as I can tell, the 12 pin com port could be a serial port:
http://www.pb-user.com/technical/bulletins/motherboard/tempest2/
or an EISCA port:
http://www.erols.com/chare/569_spec.htm
http://www.fic.com.tw/techsupport/faq/faqsgeneral.htm
or a mystery port:
http://www.lysator.liu.se/amiga/hard/guide/A4000Hardware.guide?Motherboard%20Jumpers

Without knowing how the thing is labeled, I really can't even begin to guess beyond that...

Hope it helps!

The 12 Pin connecter says only that is its a com port.. I would assume it is for a serial port, but not sure of the pinout configuration. I will dabble with it over the next couple weeks when I get a chance to trace the pinout. The exact text on the 12 pin connections is "CN6 COM PORT"..

I don't think it will be long now.. :)

Ok, perhaps a silly question....

The floppy connections, did I miss something or not, there is a pair of 27 connecters, what is the pinout to connect a notebook floppy to them. Is it just 1 to 1 and my notebook floppy drive has 26 lines and I would guess that the 27th on the WP is a ground shield ???

I got a dead Toshiba notebook with a external floppy and I want to connect the external port from the notebook to the leads on the WP and mount the port on the WP's case.

Yes, I think it is possible. The hardware is there. It's just figuring out the correct pin connections and maybe
some extra components. I'm working on all that. Keep an eye on my site:

If the floppy connector is there, you only have to connect your laptop floppy, activate it in the CMOS setup and you're ready to go.
If it isn't there then it is also lacking a fuse. Without this one you don't have power for the floppy. I just soldered in a wire and it works.

You're right. The board is lacking some components to use the VGA CONN. I'm going to try to let it work in some way.

>> As to the unknown 10-pin connector location, is it possible this is for a serial port using a non-standard MB connection?

If you mean by this CN20 near to the VGA CONN you are far off. It feeds the VGA signals directly without filtering or buffering.
I managed to connect a CRT display and it works!

In this case I advise you to be vary carefull when you start with your solder iron.

The serial ports are there and active but not real RS-232 compatible because it is lacking the needed voltages. So in this case you would need serial port
driver chip and that one needs a 12volt supply which isn't available in the webplayer. I thought there are solutions and I'm getting into that.

>> Do these ideas fire anyone's juices?

Yes it did and you can read some results here:

Great site and great efforts!

The Iopener is also TTL so I searched and found some possibly relevant info from the iopener section:

Thread on serial mod including a board someone is selling

Another serial port thread that is over MY head

That was something I was thinking about. I have a MAX232 but that doesn't give us a full supported RS232.
It could be usefull though for some purposes that done need all signals.
So we have to look into something like the second example. I was already looking into that. Maxim has a lot
of other devices that also could do the job. For me it is a matter of finding one that is easy to find for everybody,
is reasonable priced, doesn't draw too much power from the supply and some other criteria. I'll try to get something done by the end
of the week.

>> Thread on serial mod including a board someone is selling
>> Another serial port thread that is over MY head

These threads are way too long for tonight. I hope to have the courage in reading them tomorrow

>> Hope this is usefull...
yeah thanks man, anything helps.
The other threads sure look interesting but it's time to go and get some sleep now.

Webplayer video connected to VGA monitor too bright is because the webplayer video output is +3v while regular videocard output is only 0.7v.

Anyone got the floppy connector working with regular 3.5" floppy drive?

>>Webplayer video connected to VGA monitor too bright is because the webplayer video output is +3v.

I don't know where you get that idea. The RGB outputs are current outputs and with correct load of double 75ohms
you get the standard 0.7V video signal. I connected them only with single load of the monitor itself which gives about 1.5V video
signal. The 3 volts you say will only be there with the theoretical infinite load for instance when you measure the signal with
an oscilloscope without a proper dummy load you'll get very close.
