The primary application for the slot was an 8086 board which gave a
limited MSODS 2.11 capability. There was also a board that provided
what appears to be an IEEE-488 interface for an external hard disk.
There may have been an internal modem, but I never heard of it.

The pinouts for the serial ports are attached. Probably if you are
using MEX+ you can use that VT-xxx emulator. I forget whether it is
VT-100 or 52.

If you press Ctrl-Esc, you will get a status line along the bottom edge
of the screen that then permits setting a variety of things; including
key-click, screen brightness, baud rate, etc. and also displays time and
date. Pressing the Tab key while the status line is present gives a new
status line with choices of Calculator, Screen Dump, Alarms, Install,
and Exit. Each of these is a function of Valet which requires the
presence of the file VALET.VL2 on disk.
By the way, if you have not already discovered it, right shift & reset will
reset (cold boot) the Attache.

I'm not aware of any PD programs. Sydex's shareware 22DISK,
MicroSolutions commercial UniForm-PC, are two programs with that
capability, however. You are correct, they are standard 360k drives -
just 2/3rd high vice half high.

Good! Enjoy it.
