Hallo allemaal, In have given the whole project a second thought. > ... let's call it 8250IDE, I decided to rename it for three reasons: - I have several three 8050's + several loose boards laying around. - I only have the sources of the 8050. - IDE implies an IDE device. But what about using a SD-card or something else? If anybody has a better name, please let me know! > So I really started to wonder if things could not be archieved > by just by one CPU? Here I changed my mind as well. I have various reasons but I give you the two main ones: - Compatibility. Staying as close to the original 8050 hopefully guarantees no timing problems etc. causing software not to run as expected. - I can add the needed hardware by replacing the original 6530 with a board that contains some RAM, (E)EPROM and the desired interface. In this way no soldering on the original board is needed. Just an idea: this board could also contain the original 6530 or a 6532 which enables one to use at least one of the original drives as well. Could come in handy for persons owning only one 8x50 or as a mean to copy floppy disk from/to the harddisk (or whatever). But maybe some soldering is needed in need for one or two extra address lines for the EPROM. About using a SD-card: AFAIK know this is done by using the SPI protocol which is just a bit of bit-banging IMHO. For those familiar with using SD-cards, certainly Jim with his uIEC project, could the Disk Controler 6502 handle a SD-card using a 6532 or 6522? -- ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| URL: Ruud.C64.org De informatie in dit e-mailbericht is vertrouwelijk en uitsluitend bestemd voor de geadresseerde.
