In need of Rainbow PC100A eprom file

Postby Mark0x01 on Sun Mar 10, 2019 7:20 pm

Having fired up my DEC Rainbow PC100A, it is reporting a Z80 CRC error.
It may be the eproms or memory or even something else, but I have not been able to find eprom images for the 100A model.
The odd mention of A, but only B files. The Mame collection didn't even have them - they use original rom images but only have 100B.
Does anyone else have a Rainbow PC100A in their collection who could copy them for me?

Hi Mark,

Have been making enquiries for you to get this ROM dumped but wanted to check that it was still required?

Cheers,

Still hopeful.

Just need to eliminte the rom as athe cause.

These are a bit trickier to repair with the dual cpu arangement.

Thanks to exidyboy, I have now found rom images, freshly extracted, and eliminated that as an issue.
