    im after a simple schematic for a programmer for 27cxxx (27c512)
    eprom, does anyone know of any?? i havent found any on google

    ideal there would be software for linux,

    one ofher thing i was woundering about was is it possible to download
    the curent program on an eprom if theres no code protection of course,
    is there a way to do it if there is code protection???

    I've heard of a couple and some with a sourcecode you could ossibly
    compile in the linux enviroment.
    A plain eprom has no code protection, inso far as nothing protecting
    the code from being read or copied, at least that I know of (in
    theory, one may be able to program EPROMs with weak bit techniques)

    An EPROM is a simple memory device. If you can't read it then you can't use
    it either.
    An EPROM that can't be read should go into the trash.
