So I've been looking at putting a new clock crystal in my IIsi to get the full 25MHz out of it. I notice on Marc Schrier's page that you can get it up to 27.5MHz with the appropriate crystal, but any higher causes problems with the floppy controller. My question is, is there any reason not to take it up to 27MHz?
