Also the front panel of the system was a 1600 with blue and black paint. This one is a different model, so is probably their hardware. They used a form factor that was about 4" longer than 1600 boards, but their card cages could take both the 10" microdata boards, as well as 14" basic 4 ones. Also they switched to "mos" memory sooner than microdata and had a 120k and later up to 2mb (I think) versions before abandoning the micodata for 68000 cpus. The real find here is the Centronics 101 or 103, and the original basic 4 terminal. Those are kind of unusual with the later system box this represents. I would have expected to find a band printer, or a Printronix 300 with a system of this age, not the Centronics. Hope someone can snag this one. Also Al would be well served to have the documentation and tapes for the CHM collection, if not the entire system. Jim
