IBM MCA card to ID.

I have two versions of same cards, Port D-shell connector is 4 rows of holes, almost whole length of this card bracket (might be length of 36pin D shell type but thicker), 12 SRAM chips on bottom edge forward of this 32bit MCA edge connector, 5 SRAM chips at top edge towards rear. Most of area covered are ceramic PLCC types in two sizes, smaller ones 28pin and larger ones is 68pin, both sizes has quartz window in all of them. What left is mostly TTL one PAL, two IBM ASICs and four smaller ones by that odd connector in Al cap, one custom labeled 68pin plastic PLCC made by intel. One has engineering jumper wires is 74F2872, other with one engineering jumper is 93F0931, other is 93F0930. It was pulled from 3172-001 (in custom black box based on model 80-Axx planar 386dx-25 w/ cache aka motherboard) What I can determine this is interconnect boxen or something. IBM is very vague about it. Right now no boxen, too heavy. This is not OT, this parts just cleared 10 yr rule. :-) If there is demand for these, I'd like to sell or trade them. Cheers, Wizard
