Owner of three blown post diagnostic cards requires your help... Problem is that China Inc. actually went through the trouble to grind off the chip part numbers :-( Though "debug cards" can now be had for as low as $10, there is the desire to refine one's surfacemount soldering skills and to replace what looks like 10 cent TTL glue logic. Here is a picture of the same card I have, but with part numbers: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=6700762882&category=1244 All the cards sold now look like they retain their chip part numbers. If someone purchased this type of card with chip part numbers, could you either post or e-mail the numbers on the following ten chips. U2 - U3 - (looks like a 74LS02 in the above picture link) U4 - U5 - (looks like it reads 74LS04) U6 - U7 - U8 - (looks like GAL16V8) U9 - (looks like GAL16V8) U11 - U12 - (looks like 74F74) Even better would be if someone has a schematic diagram or went through the bother to trace one out. If the GAL16V8 chips are blown one would be SOL, but there is glue logic between them and the bus. As they say... Strike three and you're out...
