What is being described is almost surely a Terminet - an ASCII
teleprinter using a continuous rotating band with upright 'fingers'
containing the individual characters - these passed in front of 72
hammers, and behind them were the ribbon and paper respectively. There
were three complete sets of character fingers, thus cutting the 'latency'
of the band in thirds. When the right character arrived at the correct
position on the page, the opposing hammer fired and imprinted it.
The fingers were easily removable allowing for alternate fonts and
character sets.
The two I had were fitted with the dual cassette units (used instead of
paper tape, (but employing very much the same 'algosithm'), and I used
them in the very early 80s with a 300 Baud Novation JCat modem, to access
Compuserve and a couple of other primitive on-line services, as well as
BBSes.
The unit is well worth saving - you don't say where you are, but they
are rare now and I'm sure someone will be very happy to make it go away
for you...
Cheers

I had one of those, and loved it! Until it got mechanically flakey and I
tossed it off the balcony (I have photos). Wish I had it now!
Not light. Annoying timing to send chars. Serial I think, don't recall.
Would love to have one again, just for the noise it makes.
(Though nothing beats a Kleinschmidt drum printer for sheer pointless
racket.)

Worked great connected to my Royal AlphaTronic PC though. Just had to
make sure it sent the right number of linefeeds instead of a formfeed. :)

There was a little cardboard disk at the rear left side, belt-driven from
the platten. Notches in the edge of the disk (and, IIRC, the belt ratio)
determined the form length. I guess if this was malfunctioning, or the
disk was missing, or... then it would feed the entire box of paper...

You merely needed to punch a new VFU tape on your paper tape punch....

That's like a great "bug" in bisync protocols - you could instruct the
printer to "skip to channel n", meaning do linefeeds until there was a
hole in the nth channel on the VFU tape. By convention, channel 1 was
always punched to the top of form - issuing a "skip to channel 1" was
the HASP/3780 equivalent of an ASCII FF.
The bug is that the communication protocol allows your program to issue
a "skip to channel 0" command to the printer - but there _is_ no channel
zero on a 12-channel paper tape. Newer devices treat channel 0 as if
it were channel 1. Older, especially mechanical devices with real VFU
tapes, empty the box of paper, waiting for a non-existent channel to
respond.

Yes! Very stochastic, since the print band "scrambled" the characters
for letter print frequency or something.

When running? or when it hit the ground under your balcony?

This was 1984. I should dig out the pictures (on railing, midway, on
sidewalk).

Or to have fun throwing it off a balcony again, eh? ;)
