I am working on a project called engine simulator with a c64 and ext self made hardware (http://www.lemon64.com/forum/viewtopic. ... ght=engine
As you can read from the link above, I am going to test external hardware modules (with their dedicated sw) that communicated via hardwired signals (4-20mA I/O, digital I/O,.....) and also using TCP/IP. At the moment I have interfaced the C64 only to the hardwired signals, but I would like to add the capability to read the TCP/IP information send by these external modules.
While I have pretty good experience with hardware and 6502 assembler, I have almost none with TCP/IP, and I don't know where to start. I am thinking about using an MMC-replay+RR-NET.
Can anybody please point me to a good sorce of information about the TCP/IP (for beginners)?
If interested I could post the schemes of my self made hardware that interfaces with the C64.
