Dumb Terminals

Dumb Terminals are glass Teletypes.

 

Teletypes were in use over phone lines

in the 1920's. That's how newspapers

sent stories to their operations in different cities. They had a telegraph fax for halftone images.

 

Terminals have no computer inside.

The Teletype was a terminal to other Teletypes...on phone lines.

50 years ago...

Back in 1974, the Altair became the first

personal Computer. Hobbyists connected them to Teletypes with paper-tape readers,

and Personal Computing became reality.

 

Click on the Altair 8800 Teletype to see

what the process was like, using a computer with no monitor screen, and

no storage media

(No Disks or Thumb Drives, not even a cassette !)

 

Your phone is a terminal to the internet.

 

Steve Wozniak suggested to HP that

they could put a

6502 computer motherboard inside

a Dumb Terminal, to make a small computer.

 

 

I first played Adventure on a Dumb Terminal, a Teletype connected to a

NanoData Minicomputer of the late 1970's.

It was impressive seeing and hearing

the computer type back to me in the game.

Bob Supnik wrote the CARD to DEC-TAPE

routine for DEC.

Notice the PDP-8, and the

VT-100 dumb terminal

Digital Equipment Corporation (DEC) produced over 50,000 PDP-8 minicomputers. The PDP-8 was the first minicomputer to be commercially successful. 

Edson de Castro and Gordon Bell, both engineers at Digital Equipment Corporation (DEC), designed the initial version of the PDP-8 minicomputer.

Afterward, de Castro was frustrated by DEC’s refusal to approve a family of 16-bit computers he wanted to design. So he and other DEC engineers launched Data General in 1968 and created their own 16-bit design..

I found an old Selectric, and was thinking of

interfacing it to my Timex Sinclair...

along with a TI99/4a keyboard...

 

But then I got a Commodore 64

with a printer and floppy drive...

And wrote a music program that

could transpose, and save to the floppy...
