Jeff Rottman, master of cute quasi-portables, shows off this portable MS-DOS machine:
This computer is a Canadian built machine, called the "Hyperion", built
by Dynalogic corporation. It is an MS-DOS portable machine that includes 2
near full height 360K Floppy drives and a built in 5 inch amber montor
screen. The computer comes with 256k ram and includes a serial, parrallel
and an expansion port on the rear.
The keyboard slides in under the main unit for carrying and it comes with a
nice padded dark blue carrying case. When this machine was being advertised
in the magazines, they were bragging how easy it was to fit under an airline
I have successfully run MS-DOS 6.0 on the machine, although it was usually
bundled with a special Hyperion version of DOS 1.25 when new. The screen
can emulate both a Hercules or a CGA monitor in shades of Amber. It also
included some bundled software for business, and DOS.
I believe it was being sold in the mid to late 80's.
