anyone ever use a USB/Serial cable to connect to an Altair? I am trying
to connect my 680b to my windows 7 computer via hyper-terminal to no
avail. Any special settings I should be aware for terminal settings
(currently using 9600, 8 data bits, 1 stop bits, NONE for parity and
flow control).
Also, anyone know where I can get the ROM files for a 680b?

What you have to set
the terminal to depends on the jumper settings on
the board. It also depends on the monitor itself - there is an ACIA
version which can work with 9600 8n1, but there is also a Baudot TTY
version.
There is a listing of the monitor and VTL-2 at
http://www.altair680kit.com/manuals/Altair_680-System_Monitor_Manual-03-Bet…
(toplevel page http://www.altair680kit.com/manuals.html).
Since the monitor is only 512bytes, it is IMHO not too tedious to key in
the hex codes. The problem is the availability of 1702 PROMs and a
suitable programmer nowadays.

The 680 as far as I know does not autobaud so you need to know what the
console serial
card is set for and match that, likely much slower than 9600!
IS this running rom based monitor (turnkey) or the simpler front panel
machine
that needs software monitor loaded first to make it semi responsive.

Use an easily found (and programmed) 2716 or larger device and make an

There is for sure a BAUDOT monitor prom option for the 680b.
As you can see here,
http://www.vintagecomputer.net/MITS/680/MITS_Altair_680b_Monitor_Manual.pdf
the table of contents refers you to page 31, where the BAUDOT listing
is present.
The current loop interface in the 680b was capable of operating at 60mA,
with a BAUDOT teletype such as Model 28 as long as the loop supply was
externally provided.

I believe those were 60ma current loop. Back in the day, it wasn't
uncommon for amateur computer hobbyists to use one of the 5-level TTYs
as a printer. The driver software had to be aware of which half of the
character set was being printed ("letters" versus "figures") or you
got
gibberish. I seem to remember that it was also common practice for RTTY
operators to send something like "LTRS LTRS LTRS" when beginning a

Yes -- and it really was a loop. You'd hook all your stuff up in series
(insulated 1/4" jacks since the sleeve isn't necessarily ground) so the loop
supply could be pretty substantial. I think MJE340s were fairly standard
for solid-state switching in TUs (modems) since they could take the voltage.
Before that it was Western Electric bipolar relays (which are things of
beauty).

One LTRS is enough to reset the carriage, *but* the carriage-return dashpots
were pretty big and were slow to react or else might bounce (depending on
which way they were misadjusted) so people would end lines with something
like CR CR LF LTRS LTRS just to be safe (the LTRSes were just fill
characters). Luckily those keys were all near each other.
There was an option for some models called "USOS" (unshift on space) which
would ... well, unshift on space. But since you never know whether the
other guy has it, you can't count on it.
But anyway a model 15 etc. would be terrible for computer use since it's
missing most of the math characters. Too bad because the type was beautiful...

OIer here we had 'Carpenter relays' ehich are also thigns of beauty.
Settig nthem up is great 'fun', there are numerous adjustments (contact
position, whcih can set both the transit time and the bias distortion),
magentic bias, etc. there ae even service sheets for them.
I have a thing called a TDMS5 which is a test character generator. It can
gerneate arbitrary 5-bit characters with controllable distortion for
setting up receivers. This thing it valved. The serialiser circuit is a
ring coutner of triodes. The output is not surpisngly a carpenter relay.
And yes, it can be used to set up carpenter relays (dispaly transit time
,et by the spacing of dots on a CRT) One opther feature is that it can
produce a Quick Brown Fox message, again with controlable distortion. The
message is troed on a PCB disk with spring ocntacts onit. The disk is
moved on one character at time by a solenoid and ratchet mechanis,. And

of keys. The figure shift of QW...OP is 12...90, which makes life a

Actually, the selector magnet (receive solenoid, wahtever) would work at
quite low voltages. But it has signifcant inductance, not suprisingly.
Now, since the RL cirucit time constant is L/R, if oyuy increase the
supply voltage, you need a larger series resistance to keep the current
down to the right vlaue, so the time constant goes _down_, implying a
faster resposne. That';s why you had 80V or so on the selector magnet

A friend with an IMSAI paid good money for an ASR-33 at the time. At

The interest in 5-level machines quickly faded as their limitations

The point is, the 680 monitor did have 5-level support.

anyone ever use a USB/Serial cable to connect to an Altair? I am trying
to connect my 680b to my windows 7 computer via hyper-terminal to no
avail. Any special settings I should be aware for terminal settings
(currently using 9600, 8 data bits, 1 stop bits, NONE for parity and
flow control).
Also, anyone know where I can get the ROM files for a 680b?
Have you examined the 680 schematics (available on the web)?
A 680 can be configured in a number of ways, including various
baud rates, signaling schemes (rs-232 is just one of three
choices) and the firmware may be ASCII or Baudot. You need to
do much more investigation than "just plug it in".
