We had a similar problem, thanks to our aircon, a year or so ago. Our
big aircon is one that has dehumidifies the air, then cools it, and
finally rehumidifies it if necessary so it's not too dry (which
encourages static buildup). Well, a valve jammed, and the rehumidifier
section filled up with water and overflowed. We ended up with an
inch-deep pool of water over about half the floor -- not as serious as
Mike's incident, but still a bit messy. And dirty. What alerted us to
it initially was the smell of dampness :-(

Can anybody tell me anything about these? Found a
little something I
thought was word processor, but it actually looks like
some sort of
serial terminal using 80 column paper for output vs. a
CRT. Very compact,
kind of a neat looking little package. Googling has
come up dry.....
What you probably have is a Qwint 740 or 780 (I'd have
to see it to know what model). It was the smallest
plain paper teletype replacement probably ever built.
I worked there at Qwint (formerly Martin Research of
1970's MIKE 8008/8080 fame) between '84-85; I wrote
the service manual (which I think I still have). It's
a very sophisticated machine-don't let the size or
apparent simplicity fool you; it uses a Z-80 with bank
switching! It is possible to reink the ink cartridge
via the old WD-40 trick; don't lose it because they
are made of unobtanium. The company was bought by
Zebra (who makes the thermal bar code printers),
mostly for IP (intellectual property).

I'm looking for information on the expansion boxes for the "older"
PDP-8's (ie 8/I and 8/L). Specifically:
BA08A
BM12L
MM8I
Ideally I'd like to find user's manuals and maintenance manuals for
them, but at this point anything would be useful.
Of course, I'll also re-iterate my call for information on the DF32D
also.
Thanks.

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...

I have a DEC VT102 terminal that I got some time ago from a listmember. On
the right of the keyboard where the numeric keypad is, the keys don't match
the color of the other keys on the keyboard. The upper left key in the
keypad is gold, and the other keys on the keypad are different colors - red,
blue, white - and have editing words on them, I think words like "left,
copy, print", something like that.
My question is - is it likely that someone scavenged keys from another
non-vt100 keyboard to replace missing keys, or was this some option used
with some word processing software? If the later, I'm happy I have something
unusual. If the former, I am going to yank those keycaps off and scavenge
the "correct" keys from one of the other VT100's I'm going to junk.
Anyone know the answer?
Thanks!

I think Selectrics are pretty cool;
I'd kinda like one I could use as a printer,
and if it could be a full serial tty that would
be even cooler.
So far, I've found that IBM made the 1050 and the 2741 selectric-based console
terminals, both of which were large, heavy, and not very reliable.
Did IBM ever do any better, like say a serial module for a selectric III?
I know some of the Wheelwriter typewriters had serial ports,
but the golf ball type elements are just too much cooler.
I found some web pages that talk about Trendata ttys based on selectrics,
but very little hard info; anyone here know anything about them?
I also remember the ByteWriter and similar contraptions that strapped a
bunch of solenoids on top of a typewriter keyboard, but while
entertainingly kludgy, that lacks a certain degree of elegance.

I'm trying to resurrect a copy of Tom Pittman's 6502 Tiny Basic. Tom has paper tapes of
the binaries, and was willing to send me one in exchange for reading the tape and sending
him back some sort of machine-readable version of the contents. Not having a paper tape
reader, this would be a long, dragged-out process of my manually converting the entire
tape to binary by hand.
Is there anyone in the US that could do this for Tom? He might be happy just to have the
binary version (or the raw text) emailed to him.
If you can help, please let me know.
Bob
