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.).


So weird. The man in this photo is my dad. He died 3 years ago and I miss him so much. I''d love to know who Sarah is...

I worked in Byeshiop Manchester we sold these along side North Star Commodore Pet, Apple II, Sharp Mz80k vic20 and Cromemco.

I still have a Communicator with 10Mb hard drive, I think it will end up at Bletchley as they said $ it off.

I fell out with them somewhat after I set up sale to Kellogg''s to weight the frosties packets instead of them buying a harris mini, then when the guy came round to discuss the sale I was told to make the tea.

I said to the young lad who worked Saturdays that I thought I should set up on my own, he told the owner who sacked me.

He had previously given me my P45 when I had to visit hospital for something less than trivial.

I am not bitter as it was a really good grounding and I have had my own Computer company ever since.

He went on to manage Clive sinclairs z88 thing and Byteshop went on to be purchased by another company which still trades.
