Hi there. I am wondering, if I am upgrading my coco3 with an older dual 30 pin sim based upgrade that uses dynamic ram sims, do I need to remove the two small caps (82 and 27 pf caps on the RAS and CAS lines)? Or is that only for the 512k static ram upgrades triad one?
I wonder as I am having issues with an old ram upgrade where basic ram tests seem to pass but more involved use of ram, running applications like donkey kong seem to crash. I did remove those two caps and installed my 512k dram based ram upgrade. I'm wondering if I should have left them? Should I solder in a couple and try it again? ( I would have to order some )
Please advise. Any help appreciated.
