This is a lot of lot of vintage appearing electronic circuit board type components that I know nothing about. Great for a hobbyist. Some items are new as pictured others are used and I have no idea whether they’re useful at this point or not. There’s a lot here but what I I think I see is: Wish Board, 4 DC/DC converters, resistor networks, multiple experiment bread boards, plug in circuit board, press n seal pbc compressor film, random green board (really no idea looks like it was messed with), printed circuit resistor etch patterns, test ink pen for printed circuits etc. And computer screws as well.
