JLCPCB: 48-Hour Turnaround for 6 Layer PCBs! :
jlcpcb.com/6-layer-pcb/?from=...
The Relatively Universal ROM Programmer got some gooood upgrades. It now supports the Arduino Uno and clones, it has standalone features using the SSD1306 and the Adafruit GFX library - and it can now be calibrated using the ADC

65uino kit (ICs & sockets BACK IN STOCK!): www.imania.dk/samlesaet-hobby...
Shipping available to 51 destinations worldwide.
If you'd rather pay for a new (and much less DIY) T48 programmer you can use with Minipro, you can buy one here: s.click.aliexpress.com/e/_DcZ...

Love the compatibility between the Arduino and the 6502uino!
I had an idea on how to make the button multifunction WITH visual feedback. Have a small annunciator appear in the corner of the display that tells you what the button will do as you let it go. So it could be Enter, ESC, quit, depending on how long you have held it and after 2 to 5 options it would return to the start. Similar to the way you enter a digit by having it cycle through when setting a cheap digital clock and stopping at the chosen digit.
Great project and I will get one soon enough. Leaving room for a through hole trim pot would be nice as the tiny SMD ones appear very fragile and hard to use for older eyes.
Thanks so much! I was in the middle of writing my own Arduino firmware, but I hadn't had time to get very far. Great job!
Thank you - it's not quite there yet but it's better than nothing :)
Very very Nice! I will get one from you for sure! Thanks for sharing.
Thanks for your support! :)
yeah man. solid
Thank you!
Creative video, thanks :)
Thanks for watching :)
very nice!
Very nice video. The project will work on a Arduino mega?
Thank you. Kind of. The code needs to be changed to use another whole port, like PORTK, and it has to be wired onto it using jumper wires.. so kind of.
Interesting project. Do you thing it's possible to implement a GAL programmer in the firmware?
I doubt it - the design relies heavily on the JEDEC standard pinout of parallel EEPROMS - most pins in the same place.
Great stuff. Please would you advise which OLED displays are compatible? I have everything else on order 😊
Thank you 😀
The socket on the programmer expects the ones with the order: GND, VCC, SCL & SDA
@@AndersNielsenAA thanks but how many columns and rows?
@@whetphish SSD1306 based 128x64 ones :)
@@AndersNielsenAA many thanks - I've ordered one from Ali.
Is there an option to be able to save the rom code to the computer. Regards RL
Yes, of course. The demo you see here erases the ROM, burns a new one, and reads it back for comparison - you can skip the first two parts ;-)
Hi. If you talk about something cool like that fancy ZIF socket, you could at least say the model name, and maybe a link in the description.
Also, *brilliant project!*
Thank you - there IS a link in the description :)
@@AndersNielsenAA I missed it. I'll try to find it later thanks
@@AndersNielsenAA Found it. It just says sockets. I was expecting a more explicit link.
you should try the rp2040
Not the easiest to port to as it doesn’t have 5V tolerant IO - wouldn’t be too hard to make a RPDuino with level shifting tho :)
Can this be used on 28C256 eeproms?
Yes - I haven't tried though, so no software support. And of course it doesn't need 12V+ so it can be done on a breadboard easily - but the programmer would also be more practical.
@@AndersNielsenAA Okay thank you, I see you don't ship to the UK anymore however
@@afkafkafk luckily someone ordered a bunch of boards and is selling them on eBay :) More info on Discord if you stop by.
@@AndersNielsenAA Ooh I have just seen that, thats great, I am quite new to the concept of programming eeproms, the 28c256 has a different pinout to the 27c*, Is this something I can remap using software is it a hardware limitation? For example the A14 pin
@@afkafkafk Yes - they can be swapped in software.
