A 32-bit microprocessor is also being developed by a third person,
Gideon Zweijtzer. The new processor exists on FPGA and will interface
directly with the C-One motherboard. It will be 6502 code compatible
but expands the bus to 32 bits. The opcode set will be expanded and
enhanced to accomodate 32-bit operations

the C-One Re-Configurable Computer, a new class of computer where the
chips do not have dedicated tasks any more. By programming the FPGAs
with new cores, it should be possible to turn the C-One into clones of
famous 80's computers

The main processor of the C1 is a 65c816 processor running
approximately at 20 MHz. The 65c816 is a 6502 compatible processor
with a 24 bit address range. Extra instructions that access the full
memory range are added to the 6502 core. The C-One has a processor
slot for any other 8-bit CPU such as a real 6502

Main OS storage will be via a Compact Flash media interface with card
which is designed to hold the C-One's operating system(s) as well as
other data. There is no limit to card capacity (current Flash Cards
contain up to 512 MB memory) Flash media is hot swappable

LCD Interface (TTL LCD style)
vga
IDE Interface with DMA support 
Pci
PS/2 Keyboard port 
amiga 1200 clockports (usb cards www.e3b.de!) 
PS/2 Mouse 
DAC chip
and a 133mhz 8 bit bus (at its fastest)
gs/os movies anyone?
i recon spectrum would run fast
any1 for millions of colours and 1200x1024?
Video memory and CPU memory are still in the same memory module, but
for higher resolutions, this would mean a slowdown for the processor.
To get around this, there is a framebuffer that is only updated if the
VIC (or other cloned display chip) updates the screen. This
framebuffer has it's own strip of memory in a SIMM socket. Since the
memory on that module is not restricted to graphics, but music can
also be stored any played back without CPU usage, we call this the
MultiMedia Memory
all that is here

i like cut and paste!

So we have a (almost) A modern IIGS accelerated,onbord ide,onboard
pci,onboard custon chips (ensoniq,mega][),onboard floppy,dac chip
(mp3's any1?)scandoubled output (vga)
and the capacity for MAJOR expantion in the way of capabilities!
Is anyone sensing modern apple ][?
totally compatible
As a sideline the c64 and Supercpu- specific os (multitasking
multithreaded)now does movies http://www.king.igs.net/~billnacu/wings/
click on applications
c64 1mhz bus with a 14mhz clocked at 20mhz 65c816
