I finally fixed my H7864 PSU so I can now run my rtVAX

looks OK, but 12V looks suspicious. Is the 12V supply used by the memory?
I
don't have my print set anymore, but I highly doubt it. I
think the +/- 12 V is only used by serial comm boards, and
possibly by some graphics boards. I would not be surprised
if the regulation of the 12 V supplies is not very precise.
