I spent way too much money obtaining this on eBay, because I couldn't find my copy. Must have thrown it out decades ago because it didn't match any prototype we built.
The Jaguar System ERS, ca. 1989
Jaguar/Hurricane/Tessaract was the 88110 RISC desktop system Apple never shipped. Tessaract became TNT (The New Tessaract, aka 2nd gen PowerMac). We only ever had a couple of semi-functional 88110s for Tessaract before the PPC Deal of the Century happened in summer 1992.
http://bitsavers.org/pdf/apple/risc_products/jaguarSad that most of the "advanced" stuff in Jaguar, like pre-Quicktime "multimedia" woudn't have made much difference in the marketplace and it was too early for ubiquitous high-speed networking. It also was going to support up to four 88110 processors.
Oh.. it was also tied at the hip to Pink 😞
About the only architectural thing that survived was descriptor-based DMA that was part of the Mazda I/O engine.
I need to write the whole history of this someday. You can find tons of info on PDM (the first PPC Mac to ship) in places like Gary Davidian's CHM oral history. This is the system he talks about that he thought would never ship because it was incompatible with existing Mac software.
We could have ported Unix to it, but that was never even considered either by us, or the team that was working on a 88110 server in Networking and Communications. Theirs was called "Shiner" and was obviously different from what they eventually shipped with a PPC in it.
