C > COMART > Communicator   


Comart was the computer system group that took over the Byte Shop/Computerland chain when it had financial difficulties in the late 70s. They were a large company distributing North Star systems, and similar equipments. The Communicator was their first effort in distributing a British-made system.

The Communicator is a S-100 bus system based around a main chassis with a 10-slot-mother-board. The system had 64 KB of RAM and came with three variations of dual floppy disk drives.

Several S-100 boards were available. They offered Viewdata/Prestel capabilities, or 18.7 MB hard disk, with 13.4 MB cartridge backup.

The system ran CP/M operating system. A smaller system called the Educator, with networking facilities, was also available.

Chris Coggins adds:
The Communicator was upgraded over several years until the Communicator was given multi-user capability by running MP/M80 but finished off running Intel 386 processors with 512 KB RAM running CCP/M86. Hard disk had grown to 40MB Rodime drive.

David Broad sold Comart to Kode International and 2 years later it lefts it's Cambridgeshire factory and moved to Swindon. The Company went downhill, dropped the S-100 bus to use standard PC architecture but eventually closed.

Please consider donating your old computer / videogame system to or one of our partners from anywhere in the world (Europe, America, Asia, etc.).

I was initially working for the Nottingham Byte Shop just before Comart bought the chain. I then ran ByteSoft as a Comart subsidiary then worked directly for Comart, initially as Tech Support Manager, then later Marketing Manager - a post I also held at Kode, when they bought the Comart Group. I have some Comart kit including a couple of spare boards, and if I get time, I plan to rebuild a CP1520 that I have. I may still have a few boot disks and other bits around. Stacey, I''m sorry to hear about Ian - we didn''t always see eye to eye, but he was OK. I have a number of photos from the Comart/Kode era and there are at least a few of him if you''d like copies. You can reach me as

I used to sell Comart and Cromemco in the 1980s. Still have some Comart parts in the attic somewhere. Much prefer Cromemco though and still have a working system from them.
