I've got a whole ton of S-100 RAM cards of varying types (static vs. dynamic) and sizes that just don't work for one reason or another.
I've determined that these don't function by plugging them into a known-working Altair depositing and examining various addresses throughout the card. Some don't accept deposits, some don't return what was deposited (stuck bits, but usually across the whole card) and some don't appear as RAM to the machine.
Does anyone have any thoughts on how to diagnose and repair these cards?
