I finally fixed my H7864 PSU so I can now run my rtVAX 1000. However, I

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.
