 		 #147930 - Universal programmer
As each mcu have different programming modes hence different status and control pins,but all universal programmer have single
40 pin zif socket.I am not even able to manage for 89c51 and 89c2051.One way which i thought was to use 74HC245.Which is in high
impedance state when other connection are not required.But I found
that two octal buffers were required.How does these universal
programmer manages this problem ?
