I'm only a novice at architecture (programmed gameboys in my day.... last year).  More cycles per second is great, but would that even solve the problem?  I can understand the simplicity of getting more done in the same ammount of time...  Is there anything in the circuit that relies on that particular/steady clockspeed (interrupts were mentioned) (I'm thinking of old games and the audio processor on (again...) the gameboy, a "four voice" analog synth basically - when the clockspeed was increased, IE playing a game on a Super Gameboy or some newer-than-the-old-grey-brick-models, the game would technically run slightly faster and the audio would be that "percent" higher in pitch... amongst some other minor glitches... this was just a ~2% increase or so, not 33% or higher as our possible suggestion/max).  Could this be done through the HAWK mods, or would it have to be a separate addition?
Then I ask, (again, noobness showing), what controls the clock in our 800s?  Something as simple as the FSB on a normal PC?
 
Also, could you just swap out the chip itself for a better one - a simple "upgrade"?  I wouldn't think it'd be that easy, yet I'm unfamiliar with these 'vintage' architectures in comparison to stuff from the last decade.
 
I do like the thought of having a little heatsink in my synth if needed.  I think I'll fashion one anyway, a nice bright copper one.

Or put a faster processor. There are faster 8085s around, the 800'one is
running at 6MHz, it can be run at 8 MHz and there are faster (but harder to
find) versions. What about a Z80 in its place?
