Well, the DRAM circuit may work with one and not the other.
I remember going through this process once with DRAMs in a ZENITH PC/AT
clone. Their boards worked but my employer's didn't. I had to find a fix .

I'll need to look. It normally works with the front
panel on the IMSAI. I just don't recall whether it
used mwrite\ or pwr\.

I hate that when it happens. I'd sure love to put in tried
and true boards.

They might be fried and the other boards weren't sensitive
enough to it. All regulators do is control the terminator
voltage. I may be that even fried, other boards get enough
swing but not the DRAM boards. I suspect that it is more
likely a design issue though.
