Hidden MC68010?

Postby Ruptor » Sun May 08, 2022 10:50 am

I have a bunch of 68010 chips and there is a SC87842. Reading this statement about the CPU board on an Apollo DN300:
"I was expecting the CPU to be a 68010, yet this is a SC87842, which doesn't ring a bell. According to the sales brochure, this is a dedicated 32-bit VLSI processor with integral page fault hardware (as opposed to high-end models, back then, such as DN460 and DN660, featuring a 32-bit bit-slice processor and cache memory)."
Is the SC87842 actually a MC68010 because the latter has the page fault fix as described for the former?

I found a thread here:

It seems it is indeed a custom marked 68010.

Thanks. Not so rare though because I have one. It came from Wormold Fire old stock with five 68010 that is not connected to Apollo computers so maybe they labelled them custom for quick release before confirming them as 68010 officially in case they had a bug.

Hi,

Are you going to make an adapter board and plug the 68010 CPU into the QL?

I want to keep my QL as is but will probably stick one in my Atari. I was vaguely contemplating I could put a 68010 on a home made board with ram running a modified QL OS as a usable QL with completely different IO all handled by a different coprocessor. :)
