6502 RAM test.....

Post by Prime » Sat Aug 11, 2018 11:48 pm

Hi all,

Does anyone happen to have a routine to test RAM on a 6502, specifically an Acorn machine, source code would be wonderfull.

Background, trying to trace the source of the RAM faults on the System 5 and finding Acorn's SYSTEST program rather lacking......yes you found failed nibbles in that range but which bits of which bytes! And also don't clear the damn screen at the end before I've had a chance to see the fecking results!

If no one has anything I'll code something up......

Cheers.

Phill.
