Weird S100 memory board problem

[Richard A. Cini]

OK. Switches are good and I actually tried a manual deposit/examine at
boundry locations 4k, 8k, 12k and 16k. The manual test worked fine, so
I'd have to say that the memory is good.

Does anyone have a tried-and-true memory test program that's easy to
toggle in? Thanks.

Rich

Is this one of those boards where all 4 banks can be independently
mapped via jumpers or dipswitches?

Do not pass go, do not assume that a jumper or dipswitch is conducting
just because it looks installed or is closed.  Ohm them all out.

Other than that, time to check the address decoders etc.
