Hallo Nils, I had two reasons to ask if I could use a 6502: - I'm not familiar with the Atmels - I want to use the SD cards in combination with existing drives Then I suddenly remembered that PCs use a Intel 8042 micro-controller to communicate with the keyboard and that it can be addressed as an I/O port. My (obvious) question: can this be done with an Atmel uC as well? The idea behind it: treat the Atmel/SD-card combination as just another IC and you can place it in any wellknown Commodore drive. OK, the ROM has to be changed, but I'm familiar with that because of my harddisk projects. The advantages for you: - you don't have to worry about supporting all kind of commands and file formats (relative files !!!) - only one program is needed for all drives. - I don't see any reason why it can't be used in other computers as well. And about communicating with the Atmel, what about using the register set as used by IDE harddisks? One change: 256 bytes sectors instead of 512 ones for the C= drives. About using it in other computers: with 512 bytes/sector I can use it to replace the old MFM drives in my IBM-XT (clones) :) I'm looking forward to your comment! -- ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| URL: Ruud.C64.org De informatie in dit e-mailbericht is vertrouwelijk en uitsluitend bestemd voor de geadresseerde.
