much on the CPU clock. 

That reminds me of the time my best friend in 7th grade got miffed at me
because I hit the "TURBO" button while he was playing "Budokan" and some
ninja with a pair of chucks got froggy and put him on the mat because of the
extra speed.  So, he made me try it and I didn't even get past the first
fight (while he laughed at me).

... you are right, but it'd still feel "original" to me because of the same
hardware my hands were on & original video graphics running the show.  Hmfp. 
Maybe I'm just rationalizing, though.

That thing is rad. I didn't know about it. I never owned an ST, but lately
I've considered getting one. I like the all-in-one designs, but I'd probably
go for the full size rig in the end. Wait, nevermind, I seem to remember my
SO threatening bodily harm if anymore old gear showed up....
