If I provide pictures and a descriptions of the various chips, would anyone here be able to help me identify this S-100 card? First, the pictures: http://www.oz.net/~otter/Geekware/Mystery-Board-Front.JPG http://www.oz.net/~otter/Geekware/Mystery-Board-Back.JPG The largest chip is marked: AM9513PC 8148HP (c) 1980 AMD. To the right of the DIP switches are 4 socketed chips... The two smaller ones: F-74LS136PC 7935 Singapore The two larger ones: 74LS244 PC F 8226 Indonesia The other 9 chips, in no particular order... F-74LS368PC 7918 Indonesia SN74LS00n QQ8130 (has Motorola Logo) 74LS02 PC 8221 Singapore F-74LS32PC 8210 Indonesia 435 DM7476N 74LS14 F 8248 Singapore 2630 937 (has Hewlett Packard Logo) 4N26 240F Korea 4N26 231F Korea I'm assuming that this is a homebrew job. But before I make a decision on whether or not to stick it in Mintaka, or sell it, I really would like to know what this card is for. Anyone have any idea? Thanks -- Scarletdown
