I bought a Ontario government surplus Wang calculator system which had a keyboard with nixie display of results, the logic unit with core plane memory in a small suitcase which went underneath the desk and a large printer which used aluminized paper and "printed" using spark erosion on the aluminized paper to give blackened numbers. It was programmable and when running a long program you could turn the power off then later when you turned it on again, it continued the program-- a red light on the keyboard showed that it was in the middle of a program all thanks to the core plane memory which is non volatile without electrical pulses to modify the magnetic field orientation of the cores.

A place where I worked years and years ago had Wang 360SE calculators for the engineers. A full system (as we had them) was a "logic unit" which was connected by cables to 4 "display units" and one card reader. Yes, this was a time-shared calculator! Printers, expanded memory, a CRT display (and probably others) were available as add-ons. The systems as we had them configured were around $10,000 (in 1969 dollars or around $70,000 today (according to usinflationcalculator.com). They were old when I was using them in the 70's, but even so...--
