Fred and others - I stand corrected these are probably model 12 or
maybe model 16... did they network the Xenix ones? maybe that is why
there are many of them. I recall one large RS printer was with the group?
Guess I should have looked closer last time I was in that area.
on another topic we need trs 80 model 100 to give the college to go in
the tools of the journalist display need not work just look nice..
reporters used these for field reporting .
If you think about it many things are 'a tool of the journalist" gosh!
we endowed them with candle stick phones, some various other old phones,
old pens, old typewritters, studio and portable video cameras, video
recorders in many sizes and formats ... the list goes on!

I don't remember anything beyond the II/12/16 series, but no
one tells
me anything.
In addition to the model 1, . . .
The model 1 line was converted from a "component" system to a single box.
For those not familiar, it resembled a Northstar Dimension. Keyboard,
screen, two 5.25" floppies in a terminal like case. That was the model 3.
Default disk format was double density. Since the WD 179x controller
could not write a truly exact model 1 format single density disk (did not
support certain data address marks), there were some kludges and changes
in TRS-DOS, so there were minor glitches in the "upgrade path".
Radio Shack eventually cut a deal to market L-DOS as TRS-DOS 6.
("And Randy Cook is now finally collecting royalties!")
Soon, the model 4 was made available - same basic machine with 80x24 video
(V 51x16), green screen, a few missing keys provided, and ability to
remap the ROM from the memory map. Finally, CP/M was available without
memory remapping hardware, nor software kludge of having TPA not in low
RAM.
The college got a whole lab full of model 3's converted into model 4's, at
a price per each that was only slightly more than buying new model 4's.
Model 4P was luggable version, vaguely resembling early Compaq.
Model 2 wasn't what I would call "huge", but such is relative.
It was completely unrelated to model 1, other than name, and
naming it's OS (mutually incompatible with model 1/3) "TRS-DOS".
But, CP/M was also available.
It had an 8" drive, and "huge" external case if you wanted more
than one.
Radio Shack came out with a 68000 CPU board! and Xenix
It could be used instead of the Z80 CPU, or have BOTH! (12 and 16)
In terms of "huge", there were a few other machines that rarely,
if ever, actually made it to market, such as the "Tandy 10",
built into a desk, and sold exclusively through
"Radio Shack Computer Center"s.
