Hi everybody. I've written a PIC16C84 simulator that runs under X Windows. It's in C++ and has been compiled & run with gcc-2.5.8 on Linux and SunOS4.1.3. It accepts output from Ian King's PicTools assembler. It still needs a lot of work (e.g. it's hard-coded to read the program from "test.pt") but I thought I'd tell you all about it in case somebody wants to play with it / help develop it. I've kept the other PIC processors in mind while writing it, and I think it will be easy to add support for the other chips. If you want a copy, let me know (*DON'T* send the request to the PIC list!). I'll be away on business for the next two weeks, but I'll be checking my email and will be able to respond to requests. (I just may not be able to fix bugs until I get back.) If I get deluged with requests, I'll try to find an FTP site somewhere to post it. (Suggestions for such a site are welcome.) d.
