Thank you to those who emailed me on this. I have zipped the stuff up and put it on my web page. You will find the link at: http://www.pcug.org.au/~glennpur/electron.htm The zipped file includes the assembler file for the PIC and the Borland C files including various project, header and resource files. Let me know of any wonderful enhancements that might be made to this. Note that the software will run as is (provided you have the right parallel port pins connected to the right PIC pins as explained in the software).
