Ok, some of you might have seen the board i got recently https://www.amibay.com/showthread.php?t=3079&page=126
It's a revision 9/03 mobo. First and notable defect is the U254 chip, an 74F646SPC Octal bus transceiver (by description). Although this is not a programmable IC, meaning it's of general use, i found quite a few variations of it. And not one of the various hires pics of an A3k mobo i found on the net had the exact chip. I've seen quite a few 74F646 ones, but not this particular one. So, without further ado, i'd like to know if i can use any one of the variations as an alternative.
Bought this mobo knowing that this chip was busted, so it has nothing to do with being cheated.
Once i get this cleared and order the appropriate chip, i'll have to do something with the lack of a psu. Awaiting a big delivery of power supply 15-pin sockets, due to the fact that there was a minimum order limit.
Also got me a rather nice condition A3000 case waiting to be populated
EDIT: Here's the 'chipped' chip
