I acquired a MW-520 that was headed to the dumpster. The unit was well worn and being an early [F5201A] model ..
it will only run Win95 and DOS.
The heavy case is excellent for a future SBC or a PicoITX board
I will likely strip for a few parts, but have a couple of questions.
1. Did Motorola have a special tool to tighten the hex nuts for the Power switch and Reset button?
None of my special tools/spanners would work.
2. What were the pin assignments of the DB-9 for the keyboard connector?
A quick scan inside -- I saw the PIC processor and breakout for the 12 VDC (2 lights above keyboard)
Is it as simple as the standard PC keyboard; mouse/touch pad pin assignments; and power (12 VDC) in the DB-9 shell?

I will answer my first question !1. Did Motorola have a special tool to tighten the hex nuts for the Power switch and Reset button?
None of my special tools/spanners would work.
1. The RESET push button and POWER switch are black plastic and are friction fitted. Remove these covers and the hex nuts are easily accessible. In my case, a previous service person decided to use GLUE to keep them firmly on!!
2. I am working through the tracing for the DB-9 pin assignments. Would have been nice to have a Sevrice Manual reference
