I know this is really, really old stuff. Was only wondering if there is anyone that can help me.
I did a number of designs using the PIC16C75 and still have a lot of the OTP's.
Thought I would at least ask my question, before contemplating getting new development hardware.
They were both working when I retired them, a long time ago.
They use the printer port on my pc. PC sends out a 150ms pulse, but nothing happens from the other end. Any ideas will be great!
Thanks in advance!
