OK,

I've run across some oddball parts before, but these take the cake.

Chip 1:
AMI 8130VB
C 2618 KOREA
311660

Chip 2:
AMI 8221CLK
C2620 KOREA
311666

The drawer label that was in with the chips were labeled 311660 and 311666.

Any idea on whose custom chips these are and what they are? I have a bunch of each...

Thanks!

RJ
 
Here's another one I can't ID...

82S137 PROM chip...

Labeled: 33721-01

Checksum: 185F
CRC-16: 0000B315
CRC-32: 87DCCAB8

ROMIdent doesn't know it... Google doesn't know anything about the part # or CRC-32 (which is what MAME uses)...

Anyone?
