Huh?
Maybe a copy and paste from Wikipedia will make more sense.
https://en.wikipedia.org/wiki/Amiga_Hombre_chipsetHombre is a RISC chipset for the Amiga designed by Commodore, intended as the basis of its next generation game machine called CD64.
Commodore also planned to build a 3D accelerator PCI card based on Hombre. Hombre was canceled along with the bankruptcy of Commodore International.
"In 1993, Commodore International ceased the development of the AAA chipset and began to design a new 64-bit 3D graphics chipset based on Hewlett-Packard's PA-RISC architecture to serve as the new basis of the Amiga personal computer series. It was codenamed Hombre (pronounced "ómbre" which means man in Spanish) and was developed in conjunction with over an estimated eighteen-month period.
Hombre is based around two chips: a System Controller chip and a Display Controller chip."
"The System Controller chip was designed by Dr. Ed Hepler, well known as the designer of the AAA Andrea chip. The chip is similar in principle to the chip bus controller found in Agnus, Alice, and Andrea of the Amiga chipsets. The chip features the following:
A 100+ MHz PA-7150 SIMD microprocessor
An advanced DMA engine and blitter with 3D texture mapping and gouraud shading
16-bit resolution sound processor with eight voices"
"The Display Controller Chip was designed by Tim McDonald, also known as the designer of the AAA Monica chip. It is similar in principle to the Denise, Lisa, and Monica chips found on original Amigas. In addition, the chipset also supported future official or third party upgrades through extension for an external PA-RISC processor.
These chips and some other circuitry would be part of a PCI card, through the ReTargetable Graphics system."
The PA-7150 would therefore be the main cpu in the "CD64", or mostly used for driving the graphics hardware when used on a PCI card.
My guess is that even the proposed 3d workstation would have been sold with only the PA-7150 for a cpu, although it seems likely that you could add another cpu as well.
IMO If commodore had survived then it's more likely a system with 68060, AGA and tseng labs graphics card (IIRC) and using PCI as well as/instead of zorro would have been what they actually released as Dave Haynie was tinkering with that and commodore historically only ship things based off skunk work projects (and if other things do ship then they stink).
It's a pity the February 1991 proposal to switch AA to 1 micron CMOS and implement 16/32 bit chunky modes with 4x memory bandwidth and 2x floppy bandwidth, was passed on. Probably because it would have made AAA irrelevant. The proposal appears to have been recycled as AA+ in 1992.
