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.
