Another quick update - looks like there's at least four serial ports available via the DD50 connector. I'll need to re-assemble the machine and also get some C-size NiCds to properly test out the connections. I'll also need to sort out an MS-DOS machine with a serial port to try transferring some software ... either my IBM Model 5155 Portable PC or a 386SX machine I have.

I have updated my Github with the pinout I've discovered so far:

I will need to disassemble the machine at least one more time so I can dump the ROMs (need a converter board) and to replace the LTC-7PN lithium backup battery module.
