"Computer Memory is a standard SD-Ram module of up to 1GB size, multimedia memory of up to 128MB is a standard SIMM module. Minimum is 4MB of multimedia memory and 16M main memory."
"The main processor of the C1 is a 65c816 processor running at approximately 20 MHz. The 65c816 is a 6502 compatible processor with a 24 bit address range and 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, Z80, 6809 or even the Z8S180."

Sounds slightly expensive for a C-64 but.. I guess when they start selling millions as mp3 players, picture viewers, game consoles, web browsers (use updated version of linux), they might be able to reduce the price a bit.
