ZX-286/PCAT

The ZX-286/AT is an IBM compatible, complete Multibus I microcomputer system. It provides up to 1 MB of on-board zero wait state DRAM and support for floppy disk devices. Each device can be 360KB and/or high capacity 1.2 diskette drives.

Two twenty-eight pin JEDEC sockets are provided on-board for up to 256KB EPROM. The LBX connector provides for off-board memory expansion to 14MB.

The ZX-286/AT supports CGA, EGA, VGA, IBM monochrome and Hercules monochrome.
Application software developed using MS-DOS can be executed on the ZX-286/AT.

This is an ideal product solution for the OEM or system integrator who wants full PC/AT compatibility with Multibus I. This compatibility permits the utilization of a wide variety of MS-DOS based application software. The ZX-286/AT complies with IEEE-796 Multibus specifications.
