The Lambda Physik FL 580 Scan Control device used a TRS 80 Model 1 as it's computer. And it's orange.
The Lambda Physik unit powers up and responds to front panel toggle switches. The scan control unit was attached to the TRS 80 Model 1 via the expansion port. The card cage system would likely have been accessed by running a SYSTEM command from the TRS 80 and then at the asterisk prompt a command like /nnnnn where nnnnn = the memory location (?) of the scan control unit. I tried /12345 but it did not activate the unit. This is the memory location of the stringy floppy.
Preliminary testing reveals a bad TRS 80 power supply, but when a working supply was used the computer was able to boot up. The computer has 16K. model 26-1006. Also attached to the TRS 80 is a set of tape control cables and a video adapter cable for some sort of closed-circuit display (I guess).
