regarding Datamaster's and such

It appears to be a three piece system from the datamaster line, with a seperate CPU tower, monitor, keyboard, and printer. Only thing is, I can find no information on this thing actually being made. I am trying to verify that the power supply is actually working, but I have no data on it. Now, I also asked about basic in ROM. Someone said they didn't. I read they did, or at least some of them did. I can't find anything on an operating system, and the thing appears to have a lot of rom chips on the board. These are the things I have found so far: IBM indicates some hardware and software options in the datamaster line in their 1982 summary documents. Nothing else indicates anything other than a one piece unit was offered. Nothing else indicates a model with this number even though this thing is tagged all over as IBM hardware made in New York. From http://oldcomputers.net/ibm5322.html The OS is listed as built in basic, and the ram card and CPU "module" in this system is the same as what you see in my tower unit. You can see the floppy controller card plugged in on the far side of the CPU card with the yellow interface cable wires. In fact, I just need to know the nominal voltages that should be found on that red power connector. I have a feeling that I am missing some +5 and +12 power feeds, but I need to know what I am looking at. I measured using chassis ground and only got voltages on a couple of pins, and they all appeared to be negative. I think I am going to have to open the power supply, but those large caps always make me nervous. This is the same board, way different format, and all genuine IBM. I have that same green monitor in a separate unit with two cables that connect back to the tower. It has two legs that go up in the monitor cabinet that the thing can lift and drop on, and tilt. It has been in "storage" for a while, so I rather clean it up before I take any pictures of it. Maybe I'll get a chance to do that next week. If I need any software or 8" floppies where can I find those? And is there any refrence manuals? You would think someone could find this stuff online someplace.
