Mountain Computer developed it and initially released it under their brand, but it was better than the 32-column model HP initially introduced, so HP acquired the rights to re-brand it and sell it as an HP Product, similar to the way they acquired/sold the AMPI STATS ROM for the 71B.

I never owned one, so not sure if HP printed their own manual, but I would guess not; the AMPI STATS ROM was sold by HP with the original AMPI manual which had only AMPI Copyright. I have seen many Mountain Computer Manuals, but never an HP Manual, for this device.

I also don't know if Mountain continued to sell it under their own brand once HP acquired it, but I'd guess not.
