That wasn’t an HP product. It was written by Insignia Solutions and ran on multiple platforms.

I had it on my Mac LCII in 1992. It barely ran well enough to run older DOS IDEs for college. Later I bought an accelerator (40Mhz 68030) and it ran better.

IIRC, I had that on my Atari ST as well, and it very slowly booted Dos 3.3 and a few basic programs.. enough for me to use turbo-C or Watcom C to compile a basic .c program to display a .pcx file.

Right, Insignia. That was it. But it was a product that HP resold in some fashion.
