Nostalgia
This is the equipment I started my NC Programming career on. It was used to program 3 Axis NC (Numerical Controlled) Drilling and routing equipment at a now-defunct company in Groton, MA.
| Teletype ASR model 33 |
A Teletype ASR model 33 terminal with Paper
tape output. As you typed on the keyboard the teletype
would punch characters one row per character on the 1" paper tape punch on the left side of the
machine, you can see the series of holes that were
punched in the paper tape. If you made a mistake you could back up a character and punch all the holes in a row or if you found out too late you needed to manually read the paper tape splice out the bad code and repair the break in the tape. Want to see one in action?
The paper tape would then be used to run
high-speed NC Drilling and Routing equipment like this used to manufacturing
printed circuit boards. These Teletype ASR model 33s are museum pieces today.
Even older... My dad used to program back in the day on Punch Cards. I remember seeing them in shoe boxes in the back seat when he would sometime bring work home.
