Comic - A Worthwhile Trade

Soda or bytes

From the December 1982 issue of Creative Computing magazine

Let’s take a quick at the three systems mentioned in this comic. I included a couple images, so you can see what these things looked like in real life.

DEC PDP-11/34

From Hackaday

Digital Equipment Corporation (DEC) introduced the PDP-11 line of computers in 1970. These computers were an important step in the history of computing and one of DEC’s most successful products. The first version of UNIX was created on a PDP-11.

The PDP-11/34 was intended to be a cheaper replacement for either the PDP-11/40 or the PDP-11/35 (based on which source you read). The 11/34 was designed to handle time-sharing, but had less memory than the previous model.

IBM System/370

From Wikipedia

IBM (which I’m sure you’ve heard of) released their System/370 line of mainframes in June of 1970. It was a follow-up on the System/360 line (obviously). IBM sold the System/370 until they were replaced by the System/390 in 1990.

VAX

From Wikipedia

VAX (or Virtual Address eXtension) was another line of computers from DEC. Introduced in 1977, the VAX was intended to be a replacement for the PDP-11. In fact, it was designed to be backwards compatible with the PDP-11.
