I am still building the timer boards like I sent to you chuck.
The pic chip I am currently using on that board is a 16f628A. The 16f628 will also work.
Since the program is setup for a 4mhz internal frequency, either chip works fine in it.
Gompy's site has all you need to build one of those I think.
If you need something I didn't post on here, just ask.
