I found some work done with. The software was huge for the hardware of the time :
Thoshiba PAP intel 8088 OS CP/M 86 with 192 k ram. A monster !
I liked the idea of 3d, drawing and formulas on the same plan of work from the same interface. no need to change software. Everything was available. (impossible to execute several programs at the same time). It was another planet.
I think it was 30 years ago or more.
