Current version from repository has already this feature. Try it. If you have a problem with compilation add spaces around "format" -> " format " in ./src/error.h ( macros _ERROR, ERROR and MESSAGE )

It's hard to find schematic for this version (found very poor scan), but I see it is something changed in shift registers for address. Do you have jumpers set to old version (version 3 not 5.0e - jumpers near DB25 connector ) ? Currently I cannot check it because I have no willem board.

What types of chip do you tried ?

"Python is actually a wrapper to make C easier. It is interpreted, true, but a lot of system calls available in C are available in Python. Not that Geepro should use Python, I was curious what your thoughts are." So, maybe only plugins for ICs should be in Python and the rest in C/C++. This approach would eliminate necessity of recompilation code to add new IC. But as I mentioned above, I have no experience with Python.

Thanks, done. Time will show it work or not. Python - no I have no experience with it, and the syntax is not convenient for me (waf was implemented by yannick ). There is also some of low level code, and using for it interpreter is mediocre idea in my opinion, but .... I also thought to rebuild it to the model: engine in command line and GUI in C++, but using then for it Python or Java would be good choice.

Hi to all, At first sorry for retarded reply, I have no notification when a new post appear on this forum. The high voltage programmers are still expensive, the cheap ones are mostly for EEPROM only. LPT Willem is very simplified programmer and do not let many features like read signatures (need A9 to be rised to Vpp), programm some 28xx chip (need Vcc rise to 6V). It is also pure design (address and data line is serialized in communication with PC, makes it slowly, no controll on CE, dipsw as configuration)....

I am planning to clean the code, repair broken 27512, and add support for 29xx and...

No, not for now. I think sooner will be adapter to connect willem to real USB. I...
