Motorola 930386

hi trying to find some info on some chips I have.
i cant find any mention of the 930386

Will see wat others come up with, but Motorola made a lot of one off custom or ASIC chips.
If this is one, then there may be no public info on them
If you can put a picture up.. what package are the chips & any other markings including the under-side

[bobbymoon]

here is the picture I will have to get an underside one in the morning

nice old packages from 1973
on first glance custom rom chips.. more value in their looks than ic value.

could also be a equivalent to a intel 3002 bit-slice

only to know is if there are spares is open the lid on one.

EDIT.. can't be.. as date is too early.. 3002 was release 1974
so ROM the most likely

Thanks again for the info. I really appreciate it. I am new to the collecting side of electronics. I got my associate's degree in electronics and acquired these and many other chips from an estate while in school, and they have been in my basement ever since.

Lots of pins, probably a MaskROM of some sort with custom I/O

Too many pins to be a standard ROM product from that era usually

Well, I may have answered my own question. after looking at the chips I realized that I had some Texas Instruments IC's labeled with the same 930486 but were also labeled with TMS4100, so according to the datasheet below the TMS4100 JC is a character generator so I am assuming that the Motorola chip is a copy of or equivalent to a TMS4100?

also for some reason one of the Texas instrument chips is labeled TMX4100

character generator is a fance ROM so makes sense
TMX is a prototype part, so thats a cool one too

Seems to be MCM1130L then. From Motorola 1972 data book, page 487:

Thank you, I was unable to find the Motorola equivalent to the TMS4100.
