EPROM burning 21/25V 2.

 As it wasn't a big deal project, I made the drawings fast, and ordered the boards. Also as I didn't want to use some fancy SMPS for the boost voltage conversion, so I picked the good old MC34063 used a switchable feedback divider and that's it.

The board is arriving from the JLCPCB, with the cheapest manufacturing and shipment method. I left this project laying around for a long while now. I'm not willing to pay any extra for my laziness.
