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???

cheers

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.
