We have little information about this computer which was manufactured and exported by Asia Commercial Co. Ltd, a company based in Hong-Kong.

The ACC-8000 was one of the rare machine of the time to be equipped we three microprocessors: a MOS 6502, a Zilog Z80 and a Motorola 6809.

Thanks to its 6502, it was fully compatible with the Apple IIe but had built-in several features that were optional in the genuine Apple machine: a 80-column card, a floppy disk controller, a backed-up real time clock, Parallel and Serial interfaces, and 128 KB of RAM.

The ACC-8000 was also delivered with the CP/M 3.0 operating system and could run the wide range of CP/M professional software. Moreover ACC also provided the Flex OS which allowed the computer to run all the 6809/Flex based programs.

The computer was solidly built. It had a very good mechanical keyboard and several interesting features, like three different video outputs - RGB, NTSC/PAL and monochrome composite.
Oddly enough, in spite of its advanced features, this computer didn't meet any success. Nowadays, it seems to be a rare item.
