  Easiest thing would be to find an old Magic Sac cartridge (the early
MAC emulator) minus the ROMS - I believe if you pop a battery in there, it has
a clock that will work fine for you.  I personally use the clock built
into my Deskcart cartridge...

  There are various differences between the ST and STe series, most notably
enhanced color (4096 colors, instead of 512 palette) and stereo sound.
Also a newer TOS (like DOS on the IBM), etc.  An STe owner could better
compare...  Oh, a biggie: ALOT easier to upgrade the ram of an STe -
just pop in some SIMMS (whereas with the ST you need a memory board
setup to upgrade)...  As for Mega, I believe the main difference is
a couple extra expansion port(s)....

  Nah, I like my 1.4s...

  There are two 16mhz 68000 upgrades - by ICD (AdSpeed) and the Turbo16
by Jim Allen.  A 20mhz version by Jim Allen is supposed to be coming
soon.  Then there is the Gadgets by Small 68030 upgrade, which I believe
is at 32mhz (Dave?)...

  No problem...
