Neal, I must ask you to clarify whether you mean 65c02 or 6502. Its an important distinction because the 65c02 has an extended instruction set and the JMP ($xxxx) bug fixed. It is my understanding that Jeri is emulating a 6502 using a VHDL core and tacking on the logic necessary to emulate the 6510 on-board I/O register and extended DMA. Thus what we end up with is an emulated 6510 NOT 65c02. It will be important to know this the first time you try to BRA ;-) --- email@example.com wrote: > my two-cents worth.... > > The enhanced graphics means that there is a lot more > data to shuffle > around... this necessitates faster disk access (ie > JiffyDOS, parallel, > harddisks, etc) and faster memory calcs and > transfers (ie faster CPU).
