So what is the Chameleon really then ?   Message List

Re: So what is the Chameleon really then ?

Hi there,

Well I'd buy it just for a FPGA on a cart .. so there you have one
customer! :-)

So if the 6502 and VIC cores are accessing their own private RAM on
the cart, can they get access to the memory space of the real C64 ?
Or do they have to page it in via something like a REC ?

What about peripherals ? (joysticks, user port devices, devices on
the serial bus etc) Would you have to page the carts RAM down into
the the C64 RAM, then have the real 6510 pick up where the 6502 core
left off and access the device, copy the data into the C64 RAM and
then have the 6502 core take over again and page the data from real
RAM back into the cart and process it .... my head hurts now :-)

Does sound to be a fun project though :-)

Regards

Mark
