True. The Atari drives had internal rom mods to speed
them up from
19.2kbps to 38.4, 54.4, and 108kbps. Made by ICD, CSS, and Happy among
others. They used interleaving for the most part except for the Happy
which buffered an entire track at a time. You could read an entire 92k
floppy in something like 10 seconds.
Yes, as mentioned before I really like my Happy-upgraded 810.
A huge difference between it and a normal 810. I don't think a lot
of people bought the Happy upgrade for the speed increase though, but
for it's copying capabilities.
