...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.
