Have a suspect bad pallet ram on Missile Command, and I see that it is on the CPU memory map so I should be able to get to it from the fluke. Now it is only 4 bits wide (and only uses 8 addresses) so I can just do it manually but I have seen this on other boards before and never could find a way to use the fluke to test these 4 bit rams. Would also assume it could be a problem for 68000 based boards which use 16bit wide memory.
