Hallo allemaal, Many thank for those who answered. Hallo Bill, > I have printouts of a lot of this code, I have a scan of the complete code and took your advice. And in the weekend I found that some names and addresses of the 4040 code didn't match with the ones I was using in my 1541 code. That's how I found out that I made a mistake somewhere with my disassembler by giving an address the wrong name. After making a correction in my ASM file the number 13 did make sense again. The reason why I'm going to all that code is that I want to change it so it is capable of handling a harddisk a) using LBA and b) using a 4 byte pointer instead of the now used track/sector pointer. But before being able to change it, one must understand it. And the inheritance of the dual drive past doesn't make things easier. I had the idea of supporting two drives but I'm thinking of dropping this one. But I will keep the Backup command; copying the complete content of the first disk to a second one. You'll understand that I need another way to handle the BAM as well but here I will look at the sources of the 8x50. Anyway, any ideas are welcome! Regarding the hardware: a 74LS139, an IDE connector, three resistors, a LED and some wire can do the trick. OK, only 8 bits and thus waisting half of the capacity of the drive but it has it advances as well. If you are curious for more info, just ask. -- ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| URL: Ruud.C64.org De informatie in dit e-mailbericht is vertrouwelijk en uitsluitend bestemd voor de geadresseerde.
