I may need UNLESS (to improve performance) applications routinely copy the Rev 3 ROM into the RAM space it would occupy in a Rev 1 machine. That (if I grasp the concept I only read about last week) is the "shadow RAM" technique some PC clone vendors are using to improve performance. In the MS-DOS World RAM is faster memory than ROM; is that true of the IIgs? If the "shadow RAM" technique makes sense in a IIgs, would an application be able to tell the difference between a Rev 1 and Rev 3 machine? I gather our friends at DTS are making that argument (perhaps for different reasons, I get lost in the technospeak). I'm waiting for Mac SPSS-X (apparently, SPSS will give the program the SAME name as the mainframe version to indicate it does all the mainframe code will do -- due October or November) and the 25 MHz Mac IIci (scheduled for announcement along with the LapMac on 21 September <-- who says Apple doesn't "preannounce" products??? ;-) Along with similar *amazing* revelations in the next Vaporware column (coming soon), you may note that last MAY's column described the Rev 3 IIgs right on the button (I don't create the rumors, I only "borrow" them :-) Murph Sewall Vaporware? ---> [Gary Larson returns 1/1/90] Prof. of Marketing Sewall@UConnVM.BITNET Business School sewall%uconnvm.bitnet@cunyvm.cuny.edu [INTERNET] U of Connecticut {psuvax1 or mcvax }!UCONNVM.BITNET!SEWALL [UUCP] (203) 486-5246 [FAX] (203) 486-2489 [PHONE] 41 49N 72 15W [ICBM] The opposite of artificial intelligence is genuine stupidity! -+- I don't speak for my employer, though I frequently wish that I could (subject to change without notice; void where prohibited)
