What's a Convergence Technologies Series 186

Hi. This was my birthday present, and a nice one indeed. It's so cool I can't find it at all on Google. It's a little modular desktop, the CPU unit & drive unit (5.25 floppy and 10M hard drive) are separate units, latched together. Each has its own external PSU. The display looks like a proprietary serial terminal, powered off the main unit on the DB25 connector. The keyboard plugs into the display base. On front it says "Series 186" on the system module and "Hard Drive" on the drive unit. The stickers on bottom have Model numbers "CP-001/9 AA" and "HD-002 AD" respectively. Both tags say "For use with N-GEN systems" It powers up, runs through a batch job that I don't recognise - $JOB blah blah $RUN blah blah $RUN blah blah and ends up at a login prompt that I can't go around. It claims to be a "BaronData Transcription System" running (OS t1stndmp 9.7X) or OZ 4.1. If I can find a v3 or v4 DOS disk, should this guy boot from it? I want to preserve the OS on it, but I also want to log in. Doc
