21V EPROMs on a breadboard - Programming and failing to erase them..

Universal ROM programmer on a breadboard capable of programming even the 21V "high voltage programmable" EPROMs. In this video we successfully program a 21 Volt EPROM and also try to erase it.

(Affiliate link) 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/samlesaet-hobby... Shipping available to 51 destinations worldwide.
