I dunno if yours is on the Atari as well) will about once out of every fifteen times go into slow mode. I have an 810, and the backup could not be made using standard DOS disk copying (they use redundant sectoring on this one... good thing I have hardware-assist widgets to make my backups!). I think that what they did is made the s/w on the disk with redundant sectoring, and then put a hook into the program to go ahead and boot up on a "copied" disk, but run the clock at a super slow rate. Different from the other protection schemes, which simply go bonkers on the copies. If you wanna make a backup of your Solo Flight disk, go find someone who has a Happy Drive, an ATR8000, or the Chip (all are hardware assists to do image bit-for-bit copies of disks). Flames about the pirating possibilities with a bit-image copier can be sent to /dev/null. People have an honest need to make backups. (Curse "Electronic Arts" for using sector skewing on their latest releases... even the Chip has a heckuva time with those!!) Randal L. ("joy stick") Schwartz, esq.
