Well, that would be too bad given the fact that there is already a huge
number of applications and kernels which work with the old FPU/MMU
combination.
Sure, but the idea is to move forward from what I understand.
I'd buy such an accelerator in a heartbeat, but it should be binary
compatible with existing 68020+ code.
Apparently it will be usermode compatible with all existing 68k, but not
supervisor mode compatible, not MMU compatibale, not FPU compatible. And
it is already blazingly fast compared to most 68060 systems, without any
optimization done.
I guess it will be an AmigaOS only CPU core :)
From what I read it will replace only the CPU, so you still need the old,
fragile Amiga/Atari/Mac hardware around it? It would be great, if this could
be included into a minimig or MiST to replace all of the old hardware and
allows you to use a readily available USB mouse and keyboard.
Then it would be a new system m68k and "somebody" could write a new kernel
for this, with drivers for the FPU/MMU, instead of splitting the amiga
architecture into two incompatible ones. MiST is working great with AOS,
TOS, and I would love to have an m68k machine that can boot off an SD card
instead of a floppy disk (until you install some drivers on a IDE or SCSI
harddisk since nothing newer is directly supported).
But the nice thing about the FPGA computers is, everybody can write his own
core, so we only need to implement the original MMU/FPU in an FPGA ;-)
