I learned something new this past weekend and that is if you have a 128 or 128D and a Super Snapshot cartridge (which unfortunately only works in 64 mode) you can use not only the 128's extra RAM as a buffer when doing disk copies but, if you've 64K of video RAM, you can use that too. My Snapshot has the 32K RAM upgrade and when combined with the 192K in my 128 I can actually copy an entire single sided disk in one read/write cycle with a single floppy drive. As it happens, I have two 1571s so I doubt I'll ever use that feature but it's nice to know it's possible.
