  1. It would've been cool if Atari added extra memory to the CD unit for the Jaguar... Also I was looking at the "Motorola 68881 FPU" and thought it a nice addition to the CD unit. If you look at the "Sega CD" it had added features like a faster 68000 with hardware to support scaling and rotating. Being that the Jags 68K and DSP are the only processors to have full access memory, every little resource would've helped. Is it possible to use the 68881 to control a CD unit...? Just a geek having fun with ideas, that's all. 😉
  2. Seems like a good idea... Even with the Jag as it currently stands I often thought about the back ports on the current Jag adding some memory through those ports... To my understanding I think the DSP would be the only processor to have such access to something like that. The GPU OP probably wouldn't allow any access to any extra memory from the back unless my understanding of the Jaguar is flawed. The GPU back port is meant to display images only via the video chip receiving images from the OP; haven't find any documents to dispute those facts, which is shame for the GPU not to have access to extra memory without a workaround that's taxing to the system.
