EEPROM programmer on a breadboard capable of programming even the 21V "high voltage programmable" EPROMs.
In this video we get a little bit of help from ChatGPT to write the bit masks but of course it can't be left unattended, so we give it some help to get over the finish line.

If you'd rather pay for a new (and much less DIY) T48 programmer you can use with Minipro, you can buy one here: https://s.click.aliexpress.com/e/_DC0...

If you prefer the cheaper option I'm working on, I suggest you get a 65uino from my shop on the link below to get ready for the next video where I should have a super cheap ROM programmer shield ready for you to make/print/etch/order.

Buy a 65uino kit (ICs BACK IN STOCK!): https://www.imania.dk/samlesaethobby...
Shipping available to 51 destinations worldwide.
