.The RAMFast card has 256K of cache on it and a fast MPU which makes I/O to
.and from the hard drive much faster (though it makes the hard drive's own
.cache redundant). If I remember correctly, it can boost transfer rate up to
.300K/sec as opposed to something like 100K/sec with the Apple card. It also

	Apple's DMA card has a maximum throughput of 1 meg/second. That's
what the documentation says, to tell you where I get my stats.

	What I am interested is in someone telling us users the bootup
speed of a hard drive with a virgin copy of System 5.04 with a DMA card vs.
the RamFAST card.  And using the same interleave, just so the stats aren't
"messed up" by attempting to maximize each card's stats. (That is, an
interleave of 1 or 2, would be the best)

	Anyone interested in doing this and telling us how long it takes 
to boot? (When I time things, I time from the system beep upon turning
on/resetting the machine to when you are in total control)

.allows you to have 12 partitions under ProDOS 8 plus a few non-essential
.goodies like a password protection option and a built-in tape backup software.
.With all that the RAMFast is supposed to be perfectly matched against the
.Apple card as far as compatibility goes.

	I thought that the RamFAST was supposed to be faster under ProDOS 8
too.
