In fact, cursor & mouse moved in fixed steps, which was essential for the quick movements. I even wrote a program that took the optimized sum-of-products equations from PALASM2, created timing models from them and made an Orcad subcircuit that allowed me to simulate the PALs with the rest of my circuit in SILOS. It simply piped the drawing commands from a file into the character input of Orcad. That looked like a ghost drawing circuits at warp speed. I also had a nice ECL100K library connected with the same mechanism via Orcad to SILOS.> > PADS was a revelation. You couldn't hang a wire segment in space. > Connections weren't just line segments.

Since I have it, I should really give it a try. Stand-alone NG-spice looks interesting. cheers, Gerhard

For a schematic front end to PSpice a lot of people (especially long term pSpice users) still use Microsim Schematics (that's what Jim Thompson did). I still use it and it works fine in 64bit windows. OrCad SDT (the DOS schematic entry program) was probably the most productive schematic entry program I've ever used. It's the Vi/Emacs of the schematic world. Although I started using Protel/Altium in the 90's I still used SDT as a front end until about 10 years ago. It still has community support - for example VESA drivers supporting resolutions of up to 1600x1200 (last time I checked) were written by the user community.
