The TL866 is a ROM programmer and dumper, which was donated by Steve in 2025. It can be found in the ROM programming box along with the Micromaster LV48 Programmer and STAG SE1T UV EPROM Eraser. Unlike the LV48, it uses USB, allowing it to be used with a modern computer.

It'll read and write a huge selection of EEPROMS and EPROMS, as well as other chips such as GALs and PALs. The programmer should in theory work with Windows 7 - we had zero luck with Windows 10. It does however work in Linux using minipro. For example, to dump a 27512 chip in a DIP package, you would run:

minipro -p "27512@DIP28" -r dump.rom

There are other arguments available for writing and verifying.
