Hi,
A friend and I are reproducing some old Pal chips for some arcade remake boards. The chips are palce16v8h family. When programming does anyone know how we write protect them?
Can anyone help with this?
Thanks
Guided missiles would have they're own special write protecting system!?
Yup it's a 94 era tech we are working on... we have an appropriate programmer and our repro chips are successfully accepting the logic programs and working fine in our new boards.
It's taken along time and a lot of work so ideally we'd like to write protect them but can't seem to work out how to do it or where the security 'bit is? I was just wondering if anyone can help?

My computer outputs a file that I can see with a text editor. (or is it a HEX editor) If you know the location and bit then just go in by hand and change the bit.
