This is a 16-bit one, which are as common as dirt. Just search for "ISA
IDE" and you'll probably find one for $10 or less in about a week.
The 8-bit ones, like the Silicon Valley Computer ADP-50, are quite
*uncommon*. It's usually more common to find an 8-bit SCSI card,
although in 2007 both are equally hard to find...

New subject: Anyone know anything about old TEC Terminals?
I have an old glass TTY-type terminal made by a company called TEC.
It consists of two parts. The first part contains the main logic, all
on a board mounted in the back of the chassis), the video electronics,
power supply, and high-voltage power supply, along with monitor. The
second part is a rather clunky keyboard that attaches to the first part
with a connector cable.
The cabinets are painted almost an IBM-style blue. I don't know the
model number off the top of my head, but was wondering if anyone out
there knows anything about the history of these terminals. The thing
gives off vibes of being from the mid to late 1970's. The logic IIRC is
mostly TTL. Don't know what it uses for memory, but whatever it is,
it's got to be solid state, either shift registers, or RAM.
The thing powers up, and shows a display with some "large" and
"small"
characters (it appears to have two different font sizes), and a blinking
cursor which appears in multiple places on the screen, but doesn't
respond to any keyboard input. It has a DB-25 RS-232 connector
apparently for hooking up to a computer, but I don't know if it's wired
as DTE or DCE. There are also a bunch of dip switches on the logic
circuit board, which I assume are for setting up things like baud rate,
stop bits, number of bits,
Duplex, along with other options. There is also another DB-25 connector
on the back that appears as if it might be a "pass through" for
connecting a serial printer or something like that.
The terminal is packed away right now, but some of the recent talk about
the old Hazeltine terminals made me think of it. If there's interest, I
can dig it out and take some photos and put them up on a website for
viewing if that might help. Of course, once I dig it out, I can
probably ID the model number, then do a web search to see if I can find
anything out there, but figured I'd ask here first to see if anyone has
any information on the company or their terminals.
Thanks in advance.

The 'unviersal gender cable' is handy. Take a length of 25 way IDC ribbon
cable (e.g . strip 1 wire off some 26 way) about 2' long. Crimp a DB25
plug and a DB25 socket at each end (4 connectors total) making sure all
the pin 1s go to the same wire. Mkke a couple of them and you have no

If I did more of RS-232 troubleshooting, I'd probably want one with a

Incidentally, did any company ever wire the DB25 RS232 connector on a
_terminal_ as a DCE???? I've seen computers with connectors wired both
ways, but I've never seen a terminal that wasn't a DTE (or for that

I don't have the RS232 spec in front of me but I have always been of the
understanding that it explicitly specifies that DCE shall be a female
connector and DTE male. You should be able to simply look at the
gender of the connector and know whether it was DCE or DTE. You would also be
able to look at a cable and know (in part) what it did: a M-F cable would be
straight thru, a F-F cable would be a null modem.
It has always been a source of annoyance (to me) with such equipment that you
can't rely on this and have to check everything.
(Either that or somebody correct me about the spec.!)
I actually just received an old (70s) RS232 breakout box. Rather than having a
male and a female DB25 which would make it trivial to insert in a line, it has
two female DB25s, which not only violates the spec but pretty much guarantees
that you're going to have to monkey around with an additional gender-changing
cable whenever you use it!

Lastly, there was a very strang little terminal that used a dot-matrix

a rechargeable battery pack (not for long) that was also wired this way.
It did have a built in modem, so you could just plug a phone line into

Does anyone need the schematics for a TEC 2402?
A friend of mine long ago disposed of his old TEC 2402, but recently
found his Reference Drawings (965025-001) for the beast. Knowing that I
'collect' (accrete more like) old computer stuff, he gave the prints to
me. If anyone is interested, I can snail them out. The print set is
about 18 inches by 12 inches by .300 inches.
It's basically a bound stack of blue prints about 3/8 inch thick. Dates
from 1974/75.
Perhaps it should pass though Al's hands before it goes to its final
resting place...
For reference, this is TEC Incorporated of 2727 North Fairview Ave.,
Tuscon Arizona.

characters (it appears to have two different font sizes), and a blinking
cursor which appears in multiple places on the screen, but doesn't
respond to any keyboard input. It has a DB-25 RS-232 connector
apparently for hooking up to a computer, but I don't know if it's wired
as DTE or DCE. There are also a bunch of dip switches on the logic
circuit board, which I assume are for setting up things like baud rate,
stop bits, number of bits,
Duplex, along with other options. There is also another DB-25 connector
on the back that appears as if it might be a "pass through" for
connecting a serial printer or something like that.
The terminal is packed away right now, but some of the recent talk about
the old Hazeltine terminals made me think of it. If there's interest, I
can dig it out and take some photos and put them up on a website for
viewing if that might help. Of course, once I dig it out, I can
probably ID the model number, then do a web search to see if I can find
anything out there, but figured I'd ask here first to see if anyone has
any information on the company or their terminals.
Thanks in advance.

I have an 8-bit/XT IDE card made by Acculogic (I think
that was the name). It does have a PAL chip, in
addition to some standard TTL chips. I'll look for
one, but I was of the impression they were a little
tough to find (the ones made from discrete logic that
is).

This is a 16-bit one, which are as common as dirt.
Just search for "ISA
IDE" and you'll probably find one for $10 or less in
about a week.
The 8-bit ones, like the Silicon Valley Computer
ADP-50, are quite
*uncommon*. It's usually more common to find an
8-bit SCSI card,
although in 2007 both are equally hard to find...

Anyone have one of these they'd like to sell? I
ain't
paying $50 though. Funny "Joe" seems to
think
generic
Taiwanese stuff should command that kind of
value.
And
he has a lot of it up for bidding, all priced in
a
similar outrageous fashion.
for the edge of your seat?
