It comes with a custom Kernel and source code. http://www.cbm.sfks.se/pics/610-iec-adapter1.jpg http://www.cbm.sfks.se/pics/610-iec-adapter2.jpg I and Steve Gray have toyed with the idea to extract the IEC driver code to make a cartridge instead of replacing the kernel. Since I have a small surplus of CBM 610 cartridges fitted with dual 2764 EPROM sockets, it should be possible to manufacture a few for people who like this feature to connect a 1541 compatible floppy drive to their CBM 610/710. Now when you mention this club magazine has an article how to replace the kernel routines, I suppose it may come handy. Before looking at the article in question, would it allow soft override so one could load the new kernel routines from e.g. IEEE floppy or a cartridge and at some point swap back to the original kernel? Would it be possible to just redirect some device handling routines, possibly even have both IEC and IEEE access simultaneously? I realize strange things may happen if you have two drives on different interfaces, both listening to device #8. Besides my knowledge of German is non-existing but I'd rely on automatic translation services to get a rough understanding of the articles. One may get some funny results but most of the time it'll probably be fine. Best regards -- Anders Carlsson Message was sent through the cbm-hackers mailing listReceived on 2009-04-14 23:52:21
