I may have an opportunity to buy a few old AT&T dataphones. These were
made before AT&T was split up. They operate at 1200 bps. I already
own a faster modem, so it would not be so useful to me. Is there any
reason to buy these? They are interesting looking and obviously VERY
well made. They also come with five line office telephones, also well
made. Where can I get technical info on these. Are they worth
buying? Is there anything creative I can do with this hardware?

Is there anything creative I can do with this hardware? *---- These modems are very well made and worth the $ 5 - $ 15 they fetch at hamfests. If you know some kids who need modems for their computers, and they understand the concept of manual dialing rather than Hayes-type commands, it would be a nice gesture to buy the modems for them. I assume that you're talking about the 212A modems, and not a 202 variety. -- Mike Berger Department of Statistics, University of Illinois AT&TNET 217-244-6067 Internet berger@atropa.stat.uiuc.edu

On a related note -- we picked up about ten of these, but they have a "funky" connector wired to them -- for a PBX I imagine -- about an inch thick and 4" long. Does anyone have a wiring schematic for that type of connector so we can tear them off and put a normal DB25 on it? -- Andrew Burt uunet!isis!aburt or aburt@du.edu "There are people in the world who do not love their fellow human beings -- and I *hate* people like that" -- Tom Lehrer

I've got one of these. They are manual dial, auto answer. They work good for incoming only lines (as long as you don't mine the 1200 baud). -- Eric Kozowski kozowski@ohsu.edu Networks & Computing Dept. Oregon Health Sciences University

They sound more like the "channel interface" boxes. I think the accessory auto-dialers also had similar connectors to what you've described. -- Mike Berger Department of Statistics, University of Illinois AT&TNET 217-244-6067 Internet berger@atropa.stat.uiuc.edu
