I think that is the case. I have a large number of
Corvus physical diskettes,
disk images, and a couple of machines now that I need to get sorted out.
I should sort out all of the Concept firmware that I have. I know there was a
Concept, and a Concept-II.
Please keep us informed as things are archived? I know I need the
"MacsBug" debugging firmware images and it's likely there's a newer boot
ROM intended to support the 5.25" drive. Odd that there's not a mention
of additional software and firmware requirements in any of the
documentation. My machine came with two bins full of the little
padded-cover Corvus Concept binders. The only mention of the 5.25" floppy
was a 20-page "how to open the cover of your machine and plug the adapter
in" manual. Zero mention of software considerations.
I ended up with one loose set of CPU and memory boards and an extra "tray"
assembly with a third set of boards. This machine came from a company
who were developing third-party software for the Concept and there's a lot
of source code in the 40-odd 8" diskettes.
If you need images of the 8" system distribution, let me know. The stuff
on Bitsavers is interesting, but it's unclear whether it includes an
unmodified set of the original system software.
