    8085 Address Decoding

    Hi, I think that this looks correct, please confirm. I am ONLY showing my connection to the 62256 32k x 8 ram CE pin that I added to the web page picture, slide 15: When A13,A14,A15 are all low, the 2764 should be selected. When A15 is high, the 62256 should be selected. Keiichicom

    Is it possible to extract the program from an NEC D27128D?

    I was wondering what would be required, or if its possible, to extract an existing program from an EPROM NEC D27128D? I use Microchip PICs and a PicStart Plus, but I doubt its compatible. I also realise the output might be in hex, but any helpful clues would be useful.
