Willem Pcb 5.0e Software
[NeXT] needed an EPROM programmer to work with chips from vintage computers. Starting with a low cost programmer, he built this custom IC programmer to handle all of his programming needs.
The device is based on the Willem 5.0e programmer. [NeXT] was not satisfied with the device, noting that it had to be carefully isolated from metal surfaces during use and required setting many annoying jumpers.
I ordered a PCB 5.0E Willem. Unfortunately a Top 3000 programmer with 48pin Zif socket is over $160, the willem is definitely for techies as it requires a lot of manual setting up, but I could find no others with more than a 40 pin socket, the Willem has 32 as standard. 0e Willem Eprom Programmer Manual.

To solve these problems, he started off by dismantling the programmer. The IC sockets were moved to a daughter board, which could be mounted cleanly into the metal enclosure. Replacing the jumpers was a bit more complicated, a combination of toggle and rotary switches were chosen to make changing settings easier.

Soldering the boards together looks like it was not an easy task, with 200 solder joints needed to connect the sockets and switches. After debugging some shorts and dead connections, [NeXT] managed to finish the 1.5 year project right before his Christmas deadline.
