Display: Olivetti M24 Video Card

The Olivetti M24, Docutel M24, AT&T PC 6300, and the Xerox 6060 were all the same computer with different branding. In 1982, this design defied market wisdom by using a 8MHz 16-bit 8086 instead of the low cost variant of that chip, the 4.77MHz 8-bit 8088, in their IBM compatible. It also allowed for adding an 8087 math co-processor. The 8/16-bit expansion slots were backwards compatible with 8-bit expansion cards (PC Bus) and Olivetti's 16-bit cards but incompatible with any other 16-bit cards (AT Bus or 16-bit ISA bus). They were contained on a separate board from the Motherboard. This BUS Board and the Motherboard had identical proprietary male edge connectors. The video card had two female edge connectors to match and was used to plug the two boards together. So, this card is not, can not, be used in any other machine and is required not only for video but for any other expansion cards. This was an enhanced CGA card adding 320x400, 512x256, and 640x400 resolutions. Monochrome with 4, 8, or 16 shades in all modes except 512x256. 4, 8, or 16 colors in all modes except 512x256 (512x256 was intended for backwards compatibility with Olivetti's older non-IBM compatible Z8000 based systems and used 4 or 8 colors or monochrome shades).

Olivetti did not stop with the original M24. There were updated variants created until 1989 and later models used 386 CPUs. Just popular enough that game creators occasionally targeted the system and its "SuperCGA" and "SuperEGA" graphics.
