I used to write Pascal 6000 programs on a CDC Cyber 72.

60-bit words, 6-bit character set, and a whopping 120K of iron core memory. It was the fastest computer of its era.

Good times.

But did you write Compass? One of my last goberment contractor jobs in about 1981 was writing a Z-80 simulator in Compass on a CDC Cyber 7000. I was finally able to convince them that they could buy 10 Z-80 machines for the cost of writing a simulator.

Then I was fired. I was young but I learned fast and never made that mistake again. :o)

That’s pretty advanced stuff - I did a rudimentary inventory/sales tag program for a women’s clothing shop my wife was part owner of in BASIC on a Radio Shack 32K computer with a floppy disc drive and a dot-matrix printer - I accept no blame for the fact that the shop went belly-up years ago......

What was the deal with the dual round CRT displays? Something on the left was displayed different than on the right? Code / data?

Yep, I recognize that console. I was at the University of Colorado when they became the U.S. distributor for Pascal; so I became one of the language's early users (and advocates) in this country. It was a refreshing change from abusing Fortran for non-numerical applications. We had a CDC 6400 and NCAR up on Table Mesa had a 6600. They were the biggest machines in town. The Bureau of Standards had a CDC 3800, which they let us (students at Boulder High School) use for the course in Fortran.
