C64 EPROM PROGRAMMER (DELA EPROMMER II - REDRAWN)

DELA EPROMMER II is a eprom programmer for Commodore 64

This is a tested and working circuit board.

This is an Easy DIY circuit board, all components are through hole, marked on the PCB, Easy to solder, Easy to make ;)

This Dela Eprommer II circuit board is redrawn as original product.

Dela Eprommer II was a very popular eprom programmer for commodore 64

Dela Eprommer II eprom programmer works on Commodore 64 User Port.

You can program 2716, 2732, 2764, 27128, 27256 eproms with 12V, 21V, 25V VPP voltages with this programmer.

You can chose two different programming algorithms; fast and normal (50ms/byte). For some old eproms you can chose normal (50ms/byte) programming mode. There are also "One Byte Programming" and "eeprom erasing" functions.

Always, turn your Commodre-64 power off before pluging or unpluging this eprom programmer.

You can download DELA EPROMMER II software and some manuals from this link. (German Language)

Many thanks to Dela Elektronik GmbH for this great C64 eprom programmer.

Do not put an EPROM in the EPROMMER before Eprommer II Software started.

Commodore 64 file system records 2 bytes start adress header at the beginning of the files, but PC recorded .BIN files do not have these 2 Bytes, this difference can cause problems.

In order to protect your electronical devices, always turn off your Commodore 64 before connecting or unconnecting any device.

Gerber files can be changed at any time. Before paying for the PCBs, be sure to update your orders!

Have fun

Thank you.
