[vcf-midatlantic] MS-DOS for Hyperion?

Some school-teacher, asked me about an MS-DOS "boot disk" and BASIC for a brand "Hyperion" computer they obtained, from around 1983. They believe the OS was called "H-DOS". Anyone have a source for more Hyperion information, and for the software for this computer? Is this computer particularly noteworthy among early MS-DOS machines? - Herb -- Herbert R.
