Hallo David > http://www.classicgaming.com/vic20/texts/promenad.htm Thanks for this info. The remaining question: at what pin should one apply the 25 V to program this EPROM? For Daniele: You can find this out by programming "one" (= nothing inserted) and measuring pin 24 and 20, IMHO the best candidates. If that doesn't work out, I'll send you two real ones. ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| http://Ruud.C64.org Message was sent through the cbm-hackers mailing list
