Nicolas, Thanks for your reply. The Batronix programmer supports flash EPROMS as well (including the 29C010) in addition to a wide range of EPROMS and EEPROMS (which it can also erase). Your reply made me decide on buying it. I'll certainly order a few adaptors from you since I have no way to make PCBs myself. Did you take a look at the Batronix programmer? Would you say that it would be possible for a beginner to build the kit? The only soldering I've done so far is installing a socket in a 1541 and soldering a few cables. The assembled device is almost twice as expensive (although still affordable). /Niklas On Sat, 30 Nov 2002 10:05:09 +0100 "Nicolas Welte; address is valid for replies (Re:) only!" <firstname.lastname@example.org> wrote: > Niklas Ramsberg wrote: > > Since it can be used to program EEPROMs, I started to think it might > > be a good idea to use EEPROMs instead of EPROMS.

You can put 16 different kernals in one chip :-) Oh, > the address: http://people.freenet.de/x1541 > > There are also simple Flash programmers for the C64, I think there's > one on Funet and another one on www.6502.org. > > Nicolas > > > > Message was sent through the cbm-hackers mailing list Message was sent through the cbm-hackers mailing list
