alt Hacker NewsHi! Nice to see you here.
Yes so, this was tested within a software context; the ASIC that does the bus arbitration on the side of the 32X has some of the required pins as N/C. They do a much more interesting deep-dive on the link you added.
I initially thought the 68000 side /UWR & /LWR pins were wired to the complimentary 315-5818 ones (Since there wasn't any apparent difference between the pinouts of both).
This makes the setup a bit different since you'd not be addressing the cart's PSRAM, but instead, the 32X's SDRAM. With XIP (Like on the Jaguar port) you could probably pull it off (Not sure if you'd be able to cram the entire Busybox environment but maybe a small program could do it).
Good thing is, this is actual Linux (And not uCLinux) so there's still stuff that can be disabled further if for some reason it can't fit still on the available memory.
I was actually thinking, if memory is the bottleneck; I could always go with the Saturn instead (Or find a way to have the 32X catridge writes go through…; but I’m no EE unfortunately).
I do recall having a RAM expansion cartridge in mine that could possibly be used to fit more stuff if the main 2MBs it had were too little to hold Linux.
You got me thinking…
