Hi!
Actually I want to know that how mutiple ICs can be detector in single socket. What I mean For example that
1, if in my own programmer i use 40-pin ZIF and want to use 89C51 and 89C2051 in same.
2, if for example i want to program 2716,2732,.. in single ZIF socket.
What scheme of mechanisum I should use.
I think using Relays will make my programmer costly and using CMOS switches will make it to complex to be built.
