Arduino 27c256 eprom programmer10/28/2023 So: I need a small, not particularly powerful computer, but with a good amount of digital I/O pins. If I had the space to setup my RiscPC I might have been tempted to program it via its parallel printer port … but I don’t really have the space, and I’d ideally like the programmer to be small, that I can leave in a box when I don’t need it. Programming a parallel EEPROM is nice and logical and straightforward, and can be done with very few components. There’s no blanking-under-UV process, no special programming voltage required … I always feel like EEPROMs behave how you’d expect a programmable, read-only memory component to behave. I like EEPROMs, certainly compared to EPROMs. I’ve been experimenting with BBC micros, and building my own DIY-6502 single-board computer. There’s been a number of occasions recently where I’ve needed to program a parallel EEPROM. I should be documenting before I start on the next one.Īnyway, here’s one that’s been half-written-up for a while, that’s nice and self-contained. Which is a poor habit to get into, I admit. I’ve had so many projects on, but I’ve not been able to spend a serious amount of time documenting them. Not posted in a while, have I? It’s not because I haven’t been tinkering – actually, it’s the reverse.
