I found an ADM 3A dumb terminal. My grandfather originally used it for radio.

Any updates on the 3A restoration? If it completely works, it will probably go for a lot of cash on ebay. Otherwise hold on to it and find an Altair or IMSAI to hook it up to. This was classic stuff during the 70's microcomputer revolution.

Actually my dad threw it away because it was taking up room in my garage.

It's a classic machine, although now it's kind of useless because it needs a mainframe computer to work.

My grandfather originally used it for HAM radio using a modified 25 pin connector. I found the connector but am still looking for the old radio equipment.

The E.D.P stands for Electronic Data Processing, what companies called computers before everybody had one.

It is a shame it was thrown away. Even if its not working, it can be restored.

It's always a good idea to check with somebody first.

There are plenty of collectors who would gladly pay for shipping, even for a non-working unit, or drive long distances to pick it up. Craigslist postings are free.

Also, the CRT is considered household hazardous waste in many states.

@fang64 I had mine hooked up to a laptop a couple years ago, I found a basic enough chat program and was able to use jabber on it.

WHAT? needs a modem to operate? needs a mainframe to operate? hell no. it's a dumb terminal, it'll work with pretty much anything with a serial port.

There's no batteries in there, so it's probably coffee or something, unless there's clearly an exploded capacitor (which wasn't obvious from what I saw in the video)

Anyway, a dumb terminal can easily be hooked up to any computer with a serial port. I put linux on an old computer a couple years ago and hooked up the adm3a to it and it worked.

@ninjakind you fails

Wow and i woulda paid for one nicely for an altair...

and it got pitched because of an idiot

lol

[steven111696]

called a dumb terminal because nothing is in it meaning hardware

[zowki]

You shouldn't have thrown that thing away. There are people desperate enough to fish out thousands of dollars for that. **hint hint**

If you are much of a Linux/Unix user or are in the process of learning those operating systems you could interface it with a modern Linux install on a regular pc or a Unix machine and use it as a console/terminal for your Linux/Unix installation. This would be if you still own the thing and want to put it to "use."

Cool *thumbsUP*

You could take this apart and put an old iMac in it ;)

Would be cool huh?
