I have a RAMCHECK brand 64Kb / 256Kb DRAM chip tester...if anyone needs a chip tested, let me know. You send me the chips and I return then in whatever you sent them.

And if you're in need of other RAM chips tested, I have a unit that does 64K x 1, 64K x 4, 256K x 1, 256K x 4 and 1M x 1 DRAMs plus all 74, 40 and 45 series chips, regardless of the type (S, L, H, LS, whatever) and will even suggest direct replacements for the chips under test.
