I have a teletype 40PSU101 I can drop off at VCFMW or mail, but is is a bit
heavy.
If you have any interest, please contact me off list.
Thanks, Paul

Is this for the Dataspeed 40 terminal? If so, I have two of those and one
of them is dead. Who knows, maybe it's the power supply.

I think the MOD 40 came out in the 70s Was the Dataspeed the video?
For some reason, I never had any luck with the link, and can't find the
second one.

Yup. The model 40 band printer was something that could do 150 lpm on
14" tractor feed and could fit on a tabletop. Sold as a
Centronics/Dataproducts interfaced unit by several third-party vendors.
We had one hooked to an MDS 800 to churn out listings. A great unit for
the time.
Always sold with a an acoustic cover, however--the naked bugger was very
loud. I think I still have a set of schematics for it.

Through whatever happenstance led that stuff into my hoard, I've got
the acoustic enclosure for that printer but...not the printer. Not
really in a hurry to replace it, but it would be nice someday to see
the two reunited.

alas most of the bands have desnigrated I understand... any working ones ? ed#

Dunno--I suppose if someone were dedicated enough, it wouldn't be
horribly difficult to fabricate a band, but I suspect that deep in some
dusty warehouse there are a ton of spares. WU used these printers quite
a bit. Probably easier to find than many old type trains.
The benefit, of course is that it printed fully-formed characters at 150
lpm--i.e. a true line printer, not a character printer masquerading as one.
I still have some technical documents that I did back in the day printed
with one of these.
I do recall that we wore the zeroes out more than the other characters,
but then, we printed a lot of dumps on the thing.

You're taking about the carrier for the print pallets? Yeah, I don't
know how easy it would be to fabricate a replacement.
PDF page 388 is an example:

No matter, I seem to recall that quite a number of special ICs and
modules were used in the electronics.
I really don't know how common these are in the wild nowadays.
Probably less common than the Model 40 CRT terminals.
