I'm disinclined to count S-100 systems as they could be mix-n-match. In particular, both Cromemco and Godbout/Compupro made boards for lots of processors.
Do you have the NS32016 board, perchance?
I know about the Hyperions, but the Halikan, etc. are new to me. Got some specs and photos?
Yeah, the Cromemcos aren't really the kind of oddball systems you're looking for, but aside from the old 64K Z80 Z-2s and System 3s that everyone seems to associate with Cromemco, they were actually fairly proprietary despite using an extended S-100 bus.
Once you get into the systems with Z-80 and 680x0 CPUs on the same board, using ECC 32-bit memory, MMUs, SCSI and ESDI hard disks and tape drives running UNIX they weren't really compatible with any other hardware or operating systems. They gave DEC's comparable systems a pretty good run for the money, but alas, they didn't quite have the marketing. Like Vector and others they also had a PC-compatible in the final days, but that didn't go anywhere...
The Halikan is just a 286 large laptop, similar to a Toshiba 3100 but with an LCD screen.
The Ogivar is a clamshell 286 laptop, only noteworthy because it was one of the first and, like the Hyperion, it was Canadian.
The Seritech is just another clamshell; not sure but I think a 386sx.
Actually, the only really unusual system I have is a Sharp PC-5000 with its bubble memory cartridges and built-in thermal printer.
Depressing when I think of what I spent for some of the Cromemcos, the Halikan and the Sharp brand-new back then, not to mention the PETs, AIM-65s, M100, T3100, countless PC clones and the associated accessories... Waiting for them to get that value back as antique collectibles ;-)
