I ordered two 6808 processors from a vendor (who I'll not name until I have a chance to resolve this with them) for a Space Shuttle.
When I received the machine, it had AMI 6808P processors for both the main and sound CPUs. Machine did not boot, but sound test would play. Swapping processors, machine would boot but sound was no longer working. So clearly one of my 6808s needed replacement.
I ordered and received 2 of them, with the motorola logo and the following markings --
So, suspicious right off the bat, as everything I've seen would suggest Motorola wasn't still making these in 2008. Neither worked in either the main or sound CPU positions.
Contacted the vendor, they sent me two more, same markings, same result.
Just on a whim, I decided to treat these as if they were Hitachi 6808s and bent out pin 38. Didn't try all four, but one from each batch worked as expected when pin 38 was bent out. I did this based on the info available on Pinwiki for System 9-11, which indicates that the XTAL pin should go to ground on non-hitachi 6808s, and this ground connection should not be present for Hitachi 6808s.
So whats the likely scenario here? That these are pulled/remarked and are actually Hitachi 6808s? Something else?
Note that in the meantime I located another AMI 6808 and the main and sound CPUs are working as expected. So my game is working... I just want to let the vendor know the problem with their stock and give them a chance to respond.
