Ellen, the CMI 20meg. HD sells for about $755 from Marymac company in Texas and
is the very same one Tandy installs fro $1200. You must also make the change of
the resistor and diode I wrote about if you want to get the longest battery
life. The HD plugs right in the drive B: slot (which comes out, of course) and
the cables just plug right in. The battery pulgs into it -- all with existing
wiring.  The controller brd. slips in the Tandy board slot and bingo...it works
right off the bat. The docs are good...very good. The change in the diode I
wroe about it NOT NOT NOT hard if you can use a screw driver and soldering gun
AT ALL. But get the exact right diode and not the RS equivalent! RS repair
installs the HD IF and ONLY IF you buy Tandy's as far as I know. Marymac's JIM
might put there's in for you if you talk sweetly to him. I thought he was very
flexible. It is all portable and durable. Battery life is about 3-4 hours with
it. The model 3500 or 3500A is an indication of a minor change to the PS (which
seems to be rather insignificant) -- this serial number is stampded on the ID
plate on the bottom quite clearly.  Finally, I don't know a bit about the 5.25
inch drive, sorry. I suspect the logic of the floppy control board (on the
drive) must be the same as Tandy expects it to be and IBM may or may not match.
How about checking the question with someone like Ray Reyes on this sig. (or
you can find him on the Tandy2000 sig...he is very informed about a number of
things and that may be one of them.

There is a file in LIB 5 called LTCABL.TXT that describes how to hook up an
external 5.25" floppy to the 1400LT, including the proper line arrangement.
