I am new to the S-100 area, and having gotten an old IMSAI chassis with power
supply and motherboard, I am eager to make sure it's up to snuff before I
plug anything else into it. I am getting +11 on pins 1 & 51, +21 on 2, -21 on
52, 0 on the grounds (20,50,70,100) and about 2.3 or 4 everywhere else. Is this
normal? If not, a) is it within acceptability and b) if not, what kinds of 
hints can you-all offer to help fix same? These values were tested WITHOUT 
boards, and I only plan to put in 1-3 boards in for quite a while.
The chassis in question is for the PCS-80/15 microcomputer, with an EXP-10
motherboard(REV 2.2,AR 1.2) by Imsai. Also, anyone having information as to
who might be doing support on these things, please, please send me mail at
the address below. Thanks.

			Thanks in advance,
