PetersonAfter getting access to Fat Mac a few days ago, I tried bringing up the "Ram" disk driver supplied with the Lisa Workshop. This simulates a 320K floppy by using the Fat Mac's extra address space as an in-memory disk drive. By copying the System and Finder to it, you can make it the "startup" disk. The results are ASTOUNDING. For example, starting up a MacPaint document normally takes 27 seconds, just takes four with the Ram disk. Exiting back to the Finder takes three seconds instead of the usual 15. Desk accessories, dialogs and the like all pop up instantly - In short, all of the normal "tedious" delays caused by the floppy drive vanish. It really points out both how much horsepower the Mac really has, and where the system bottleneck is. -------
