	I got a peek at a Mac Plus yesterday, and it's pretty much
what the rumors have projected: an old mac with new ROM, a double-sided
drive, 1 Meg RAM, and a SCSI interface.  The modem and printer ports
are little round connectors, making room for the SCSI port.  The only
thing I found surprising was the way they fit 1 Meg onto the motherboard.
The RAM chips are on little strips of pc board (four of them, with 8 chips
each) which are mounted at a 45 degree angle to the main digital board.  I
just hope the ventilation is up to it.
	My one dissapointment was that they stuck with the 8 Mhz 68000,
instead of using the 12 Mhz model (which is used in the Laserwriter).
I can't see any technical or compatibility problem that precludes use of
the 12 Mhz chip, especially since a company is advertising (in Jan MacWorld)
a 12 Mhz daughter board for the Mac.  Would the 12 Mhz chip require faster
memory, or screw up some old software?  I was hoping that we wouldn't have
to wait for the 68020 Mac for significant speed improvements, but I guess
we will.
