SYSTEM FORMULET INC.
BUBCOM 80

Almost nothing is known about this rare japanese system... Apparently its was first marketed as the System Formulet Bubcom 80, then bought back by Fujitsu and sold as the Fujitsu Bubcom 80.

Originaly it was a CP/M machine which used Fujitsu magnetic bubble memory. It had filesystem support for the bubble memory cartridge right in the CP/M BIOS. It seems also to have been one of the first japanese system to offer 8 colors display and is considered at the origin of the popular Fujitsu FM-8 computer (anyone can confirm that ?).

There were different versions, at least two : BC-80RN and BC-80RS with memory differences. The RN model had 64 KB RAM, and the RS ... more ?!

It was apparently possible to upgrade it with modules inserted in one of the two slots on top of the case.

Jake Christie sent us this information:
The Bubcom 80 used "bubble memory", which was supposed to be the solution to the storage limitations of 1980s microcomputers.
I believe the machine cost over 10,000 yen in Japan when it was introduced sometime between 1982 or 1984, and there was an attempt to export the Bubcom 80 to the US because it was a business computer.


We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.

 

il riferimento si trova a pag.34 del libro:
Considerations for Use of Microcomputers in Developing Country Statistical Offices: Final Report :

"In one of these system, the Bubcom 80, a 32Kb memory cartridge was priced at $ 175 in mid-1982."

Da Google Libri.

Cercando in rete ho trovato una citazione tecnica sul Bubcom 80 in cui afferma che la memoria ram ammonta a 32kb.
Quindi possiamo presupporre che fosse espandibile a 64 Kb ma la configurazione base è di 32Kb.
