Basic eprom programmer using Arduino Nano.
This is the Arduino scetch needed for an Eprom programmer for 27C256 and 27C512 Eprom chips
This project was put together using bits from other designs. The main aim was just to get a working programmer for these two chips.
This was used to program Eproms for use with various "Retro" design z80 computers, mostly based on RC2014 designs.
The circuit has been uploaded. https://github.com/coopzone-dc/Eprom-27c512-27c256/blob/main/Schematic_Eprom_2023-08-19.pdf I'm going to publish this using EasyEDA as soon as I get time.
I am going to create a instructables ... soonish
More to follow....
