Does having this option on slow the machine down in general?

I'd certianly love to.  Got a Zip to trade for my Transwarp? Have a spare
2b?  Didn't think so.  I already blew all my cash on the floptical. And it
still dosen't work.

Well, I usually trust what Howard says.  However, the machine won't get
past the "Apple IIgs" screen with the Ramfast.  At least my Apple High
speed dosen't lock up everything.

Does it make a difference that my Transwarp is 6Mhz/8k and ROM version 1.5?
