I wouldn't like >to release non-working code, but on the other hand I don't have the resources >(3-channel storage oscilloscope or logic analyzer) to analyze the problem. I have a home-made logic analyzer that I've used to analyze the IEC protocol. IIRC the C2N232 uses an at90s2313 at 8mhz? I believe I have a 2313 I can spare to build a cn232. I don't really need the connections to the c64's tape port for this right? (except maybe vcc/gnd?). I have some serial(iec) connectors I can hack up for the job but nothing to plug into the tape connector. If I do this, what should I try to sample? read the command channel? load a file? My analyzer only has 128k of ram which are good for some 128mS at about a sample per cycle. I could sample a little slower if necessary though. Comments? p.s. Yes, I'm working on a IEC<->rs232 project as well :) -Adrian Message was sent through the cbm-hackers mailing list
