…PC.

Well, kinda. The Victor demo was one of the sleaziest things I have ever done. We didn't have the 8086 version even close to running on the Victor, but we wanted to be able to show the “potential of CAD on the Victor”, so I wrote a plot-to-file driver for Interact on the Marinchip 9900. This wrote what we would call slide files today. Then I wrote a BASIC program on the Victor that read these slides and drew them on the screen using a Victor-supplied graphics driver for BASIC. It worked well enough to convince Victor and many Victor dealers that CAD on a PC was real—even if it wasn't real quite yet.
