Today I finished my adapter to make a breadbin 64 accept a 27C128 EPROM. JR sold a variety of eprom related products for the VIC-20 circa 1983, and produced the Promenade C1 EPROM programmer. Der Eprom ist gebrannt mit dem Commodore DOS und JiffyDOS. (Full article text is primarily available beginning with Issue 20. An even better deal than just buying the bare board is to add five bucks and order either board with an EPROM preprogrammed with some apps and a nice menu program. There’s a lot of practical know-how that goes into eprom programmers and Willem was quite the man in this field. The version of the JiffyDOS C64 kernal replacement is easy to determine, since it is printed on the welcome screen of a JiffyDOS-enabled C64 (see the screenshot on the. The procedure is the same as above, but instead of pin 4 of U14 use pin 5, and instead of pin 12 use pin 11.
