Microvoice Corp. (Tokyo, Japan)

Microvoice apparently sold the Formula-1 as a development system. It came standard with an EPROM (labeled “EP-ROM”) programmer with an IC socket accessible on the front. Its keyboard folds up for transport. Both the Formula-1 and the Mugen below were marketed in North America.

Its name wasn’t the only odd thing about the Mugen. Packed up for transport, it looks not much different from any other sewing-machine-format portable. open it up, and you see that it is designed to sit vertically rather than horizontally, with the display beneath the floppy drives.

Reader G. Perez adds this:

“February 6, 2013 at 11:51 am: When I was 15, visiting Japan, I worked in this company. In fact I helped set up a series of prototypes of both F1 and the computer Mungen (a symbol spiral). Sometimes to test the computer, using the the first version of Flight Simulator….hahaha!! Then I left Japan and knew no more of this small company …. Shinjuku was in office, but the factory was near the factory CANON in Kawasaki.”
