I have 2 IOs 1 v3b and 1 v5, ordered 2 K6III+ 450s for $55 each plus shipping, dropped the first one into the V5, changed SW4 and was golden at 200
v3b - takes a bit more work
R60/R61 to R184/R185
Have not verified anything about this step, just did it. lost R61, used section of paperclip instead
set up divider for U16 vIN
R342 = 10K
R343 = 10K
U16 pin 3 (vIN/vREF) = 1.25v
I need less volts than 2.0.. this is a K6-III+
moved 10K (103) from R202 to R203
installed 47K (473) in R202
*this SHOULD have given me a vcore of 1.6, but instead gave me vcore 1.48 .. I believe I'm operating near an over or underload condition somewhere
Jumped R327/R328 for 4.5x multiplier
used softfsb to go to 100 Mhz Bus
runs stably Q16 heats only under heavy CPU load and cools quickly..
note my Q16 is a 6030L. not the 28?? listed elsewhere
using stock power.
CPU has a 12V radioshack heatsink hooked to the 19Vline and dropped to ~9volts with a zener
(this required carving a hole out the back, but was kinda fun..
CPU does not appear to require a heatsink at 200Mhz, could probably live without a fan at 300 and seems to need it at 450
