There is a company that puts out a ROM upgrade for the Leading Edge Model
M that costs around $100 to $150.00 depending on how old your mother board
is.  This ROM upgrades your system so that you can run DOS 3.x and EGA on
you machine.  Unfortunately I don't have the 800 number for the company,
but, I do know I got the number at one point from Mitsubishi, since Leading
Edge Model M was built by Mitsubishi for Leading Edge and Sperry(UniSys).
In general I have found the Model M's to be solid machines as far as the
hardware is concerned.  Your video card if it is one of the old ones
can only do mono, not graphics.  If the price of the machine was right,
I would consider getting the machine, upgrade the ROM and put a video card
that can do graphics and I would bet the machine would hold up just fine
and the power supply on them can handle a lot more than you already have
in it.
