Hallo allemaal, A picture of the interface: http://www.baltissen.org/images/1541ide.jpg Hardly to see but it is a 74LS138 on top of a 244 on top of a 245 on top of the 2nd 6522. The IDE connector is glued to the 40 pins custom IC. So far things worked out fine :) I copied a floppy to the harddisk and copied it back to another floppy. So far there is only one little flaw: it takes about 3 minutes to create an image and 4.5 to restore one :( IMHO I may blame the original routines of the 1541. When creating the image I can see the harddisk LED blink about four times a second, three times when restoring one. Saving is slower because the 1541 automatically performs a verify after te writing. I'm convinced that it can be done much much faster using your own loading/saving routines but I'm already very happy that this prooves that the idea on itself works. http://www.baltissen.org/files/dc3.asm = the assembler file http://www.baltissen.org/files/dc3.bas = the basic loader and executioner z=0 : create an image run2010 -> z=3 : restore an image Remark: at this moment I can only save one image. The idea is asking first what image to use and then to alter some of the the numbers in the lines with DATA. -- ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| http://Ruud.C64.org Message was sent through the cbm-hackers mailing list
