	I've some experience with a CP/M-module for the C64 and I only can
	what Marko writes. If I wanted to change the memory configuration, I
had to 
	activate the 6510 again.
so how does this work?

The email trailer is attached by my work's server and I can't switch it
off.... they are into engine /fuel system development, though do have a few
good electronic people.... (they are mostly into hacking GameBoys)

re: developing a C64 accelerator, I was just brainstorming again (read as:
"dreaming").... thought was a scalable processor /cart using an all in one
PC running a core only emulator (and maybe an REU emu) and writing_all
/reading_IO via 1MHz DMAs to the real hardware (probably via a set of 8255
chips on a PCslot or LPT port).... upgrade the PC and upgrade the stays the same... unlike the SCPU which is 20MHz until
someone makes a faster 65816....
