Functional front panel and z80 board. Pictured running the port FF test program testing input and output to port 0xFF. Note the corresponding programmed output LEDs to the Address-Programmed Input
Serial No. MFD-1107
See the clear vinyl bubbled up? I'm not sure if that was part of the shipping that you peel off, or a protective layer meant to be a permanent part of the system. Needs attention RSN.
I have a Intersystems Model 950 set of disk drives working too. I've got a bit of RTFM to do first before trying to boot any media I may have.
I removed all the boards and the front panel (FP) board before testing the power supply. It was rock solid.
