Greetings electronics fans...
I want to make an interface of the nintendo NES with my computers' LPT...
So instead of a rom cartridge, i ll serve the data through lpt...Rom dumps will be available on hard disk...So my question is the following:
Nes is 6502-based and is clocked at 1.7 mhz...guess that this means that rom accesses will be much below <1 mhz right?
Will the lpt be able to serve data at these frequencies?
What is lpt's maximum speed?
I guess one cannot count that easily due to lots of interrupts happening here and there...
And lastly, win XP have a selection for the lpt (through the device manager), "Never use an interrupt", as well as "Use interrupt" etc...
How will these affect perfomance? Especially the "never use" one selection....
Thanks to everyone in advance....
