I know a fair bit about the Jupiter 7. This was a 2-piece
system. The keyboard was quite a bit larger than typical
keyboards, with TWO joysticks. It had a row of lighted key
switches above the keyboard. Then, there was a main box,
with power supply, 8 bit plate 1024 x 1024 graphics memory,
color look-up table, and a 6502 CPU. It also had a DMA
interface that could download images at memory speed. I
built an adapter to download images from a u-VAX.
We had one at work, and I had one on my home UVAX-II. I got
a factory test mule from Jupiter when they closed down the
graphics terminal business for something like $150. The
Jupiter 7 main box was the same width as the keyboard, about
3" tall and about 24" deep. You generally set the color
monitor on top of the Jupiter. It has a rocker power switch
and an RJ-45 jack on the front, and (I think) 5 BNCs for
video and sync out on the back, plus some DB-25's.
If it is not a Jupiter unit, it might be from an AED 512 or
similar graphics box.
