8086/8088 machines... back when it was hard to get hold of even an EGA or V=

colour monitor (CGA was too low resolution to use, can't recall what the mo=

were called). OrCAD was around then too, but some reason we used it only fo=

schematics (when we really needed to) and imported the netlist into Protel.=

send off the file (on floppy disk probably) and get it photoplotted direct =
