This is another
varient of very simple PIC16C84 programers. It's based
on: D.Tait PP and TOPIC
programers, NOPPP by M.Covington, 8 Part programer by
Stephen Nolan , and the COM84 programmer.
Since the Com84
didn't work with my com port (because it couldn't get
enought power from it) I added an external power
supplie(+12V) and a transistor to solve the problem.
You can use any
software for the Com84 programer, such as PIP02.ZIP or IC-Prog.
simple circuit doesn't has any buffers, so keep all
I made this circuit
only from parts that I had already, maybe there is some
parts that would be more suitable (ie better than the
The power supply is
+12V to +13V.
