8048 programmer, 2708 programmer, and 1702 programmer

This isn’t something I designed, but I really like building capability in my lab so I got these to help dump microcontrollers and eproms. I’ve used the mcs-48 programmer already to dump code from microcontrollers and the 2708 programmer helps not need a bunch of power supplies to read 2708s as 2716s in a conventional eprom reader. The 1702 programmer was the most difficult and the most un-needed (by me) but you never know when parts are going to go end of life and I’d have to redesign this thing and there’s no way I want to do that. I only had one issue on the whole set and that was a dual transistor I toasted on the 1702 programmer, but I always buy spares. If you want boards or spare parts let me know, hand soldering all of these once was enough for me…
