>>11880184>never happened.Not the cheapest, but far from pricy. This is from 1991, $30 for an R3000 based microcontroller off the shelf. By 1993 the price would have fallen a bit. Add an extra matrix math coprocessor into the die.
>68000 was dirt cheap and commonThe 68K had no place in the Jaguar. It was bottlenecking the system. Too weak to run games, and keep up with the two powerful RISC chips, too powerful if it was to be a sound chip controller.
>jag used two risc chipsJag uses two risc chips and one 68000. Tom runs game logic and rendering. Jerry controls the sound DSP.
Atari should've went with a more friendly and risk-free architecture while staying cost effective. Something like R3000 core with 3D coprocessor + Tom based GPU, with fewer CPU instructions + dedicated VRAM, 256KB or so, like 32X + sound DSP powered by 65C02 with small dedicated SRAM for the sound bank, all on a single chip like the later SNES revisions. That would make it work a lot more like the PS1 and give the devs an easier time.
Unlicensed internally designed RISC chip might have been dirt cheap to make, but way harder to use and full of undocumented quirks. Spending like $15-$20 more on a much more popular MIPS based solution would have been wise. They could save up everywhere else to keep the manufacturing cost low. Jaguar didn't need that CD quality sound chip when it's running mostly cartridge games. Nor it needed to have much higher color depth than SNES SuperFX games when it wasn't even capable of UV mapping.
Their objective should've been to run games with the same complexity as PS1 games but without textures, transparency, and complex shaders. Same CPU, slower RAM, much simpler GPU. And perhaps with SNES quality sounds. Making the Jaguar a poor man's PS1 would've made it more marketable to players without deep pockets and devs who wanted to make effortless ports.
