BBD-MN3010 and MN3011- is a MN3101 clock necessary?

[René Schmitz]

Interesting idea! 
Maybe use something bigger than the 8-pin varieties. Then you have enough
pins to use external clocks for the uC. I'd run the clock out of a high
speed VCO or PLL, so that I wouldn't have to use devices with ADCs. The
fact that the gap changes with clocking rate doesn't matter if one uses the
1/4 clock delayed S/H. The program would be a stupid small endless loop.

Oh, and a silly question: Can the ATtiny chips be programmed with a STK-200 ?
(Replacing discrete logic with smaller uCs is more and more appealing to me!)

Bye,
 René
