Its easy to bootstrap HP-IPL/OS, which has decent diagnostic capability to
check
out 21MX machines. Look at:

Digi-Key may have a complete replacement cable;
I'll have to look at my
2108B on Monday when I get to work. But, from memory, the cable has a 50
pin IDC edge connector on one end and a four-row IDC "transition"
connector
on the other that's soldered into the board. Part number C3PET-5006G-ND
might be it.
But you'd have to unsolder the 50-pin transition connector from the front
panel PCB. It'd be easier to cut off and replace the edge connector, I
believe.
The OEM part for the edge connector is 3M part number 3415-0001.
The cable assembly was cheaper than the connector itself, though not the
factory gray. I ordered a C3PES-5006G-ND and put it in last night. Seems
to be working fine now. IBL now loads code into memory.
Thanx again!
I wish I had a full diagnostics virtual tape image to more fully check
out on all my systems.
