I've jsut turned up the M452 schematic. Has anyone else looked at it?

It's a <expletive> RC transistorised oscillator driving a /4 divider chain. 
Are you seriously telling me you don't have a junk box full of random R's and
C's and you can't change the timing components to get whatever rate you want
out of it? 

I am very worried that people would rather use a microcontroller than change
a couple of passives. Can't anyone read a schematic and think????
