Kewl new find

I came across a deliciously mysterious computer today in a local thrift store. I took the following photos of it in various states of undress: http://www.siconic.com/crap/BMC-1.jpg http://www.siconic.com/crap/BMC-2.jpg http://www.siconic.com/crap/BMC-3.jpg http://www.siconic.com/crap/BMC-4.jpg http://www.siconic.com/crap/BMC-5.jpg http://www.siconic.com/crap/BMC-6.jpg It's a machine made by OKI of Japan (the same company apparently that made the Okidata printer line). It's called the Small Computer Model 10 (as indicated by the photo of the nameplate). At first I thought it was just some dumb terminal until I started looking closer at it and discovered it was indeed a computer. Upon examining the innards I found that it has a Z80 processor and seems to be circa 1982. I couldn't tell how much RAM it had because the chips are all funky Japanese types. My guess would be 32K-64K. As one can see from the photos, it incorporates a dot matrix printer in the main unit. If you've got one to compare to, the machine is almost exactly the same dimensions as a Sol-20 (and just as heavy). It has an expansion bus inside, and two cards are plugged in: a floppy drive controller (marked 5-FDD) and some sort of CRT interface (marked C-CRT, probably color CRT). The right-hand side has three DIN connectors, labelled L-PEN (lightpen), TV (probably an RF connector), A-CMT (?). Finally, there is a DB-25 RS-232C connector. The left-hand side features the power switch and two momentary buttons, one marked IPL and the other NMI. I was hoping when I plugged the machine in I would get output to the printer but no go. I tried blindly typing some BASIC commands like LPRINT but that had no effect. When it first turns on, there is a 3 second beep that comes out of the speaker. If I hit the IPL button it seems to reset the machine: there's a moment of about 3 seconds after pushing the button where nothing happens but then the speaker beeps for about 3 seconds again. I tried pressing various keys (like HARD COPY) but could not get any action out of the printer. I imagine it wants to be connected to a CRT. I didn't know at the time to look for a CRT so I'll probably go back tomorrow to check around. I'm also going to check for any floppy drives that might go with it. I'd like to try to hook it up to a TV but I don't know what pins I should use. I have a working scope but it's huge, old and is at my warehouse. What would be a good way to try to determine which pins carry the signal? Any help or info would be appreciated.
