Hallo Adrian, > Incidentally, doing a multimeter check on the sync pin of the > 6502 reads only 0.11v, which strikes me as being a bit low; > especially compared to the working machine's 1.13v... The only reason for this is that the 6502 is fetching a opcode every cycle ie. the 6502 does nothing or reads the same instruction all the time due to a damaged ROM or whatever has to do with the databus. This is an ideal problem to be solved using a debugger: http://home.hccnet.nl/g.baltissen/debugger.htm Hmmm, the GIF is missing :( If you need it, mail at ABP. Otherwise I (hope to) put on my site this evening. ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| http://Ruud.C64.org Message was sent through the cbm-hackers mailing list
