Nice project! Those disks look great. 18:50 OPEN is a generic command that opens a "file" (a.k.a. channel) to any device (drives, printers, etc). You are assigning file/channel number 15 to device 8. The secondary address of 15 is device-specific, and tells the 1541 that you want to open a COMMAND CHANNEL. If you had used another secondary address, it would instead tell the drive that you want to open a file for regular I/O such as read or write. Between the quotes, the first letter (N) is your command ("new"), and the zero is the drive number. This is a leftover from dual-drive units that had a single device number but contained drives "0" and "1". It is not strictly required (since on a single-drive unit the sole drive number is always zero), but considered good practice to include it. Finally, the two characters after the disk name are the disk ID, which appears to the right of the name when you list a directory. Those can be used to assign a unique ID to disks in your collection, or just for vanity (e.g.- your initials, etc). If I may, the one thing I would recommend is to run programs from the SD2IEC, and instead use the Kung Fu Flash to emulate either an Epyx Fastload or (my personal favourite) The Final Cartridge III. Those are the two major fastloader cartridges fully supported by the SD2IEC firmware and will *massively* speed up loading on both the SD2IEC and the physical 1541 (as well as saving, in the case of the FC3). Also, both of those cartridges have shortcuts for issuing disk commands. On the Epyx Fastload it's the @ symbol, and on the FC3 it's DOS"[your command here]". You'll never be stuck typing 15,8,15 again! :) -- JC
I love comments like these! Thank you! I was hoping someone would explain the command specifics to me. I definitely need to get more familiar with fastloaders now that I have a working disk drive. I actually have an original FC3 as well. I had so little time to get this project ready so I had to learn fast and use the first setup I got working. I love the Kung Fu Flash for the ease of use it provides and using fastloaders with the SD2IEC is a bit "boring", but with a real drive it provides a lot more authentic experience. I need to look into JiffyDOS and stuff too now.
