All of Data General's CAD systems ran on DG Mainframes and used DG graphics terminals. These terminals were slow and expensive. Since the terminal firmware had been written by our group, and the PC firmware had been written by our group, so it made sense for us to write a terminal emulator for our CAD work. The emulator was about 70K lines of 8086 assembler and produced a 64K COM/ROM image. On 386/16 PCs it was ten times faster than the original terminal, and even emulated smooth scroll, 648x240 graphics, custom characters and colors, and horizontal split-screen panning. Our ROM BIOS was modified to detect the plug-in ROM and offer it during boot up, for diskless terminal emulation mode.

The project was cancelled for political reasons.
