I know your site Mark. I've been reading and re-reading it.
I'll be ordering some atmega48, 88 and 168 tonight.
I was hoping I could bug you for some clarifications?!
For some reason I can't scroll up and down your HUGE list of supported devices in the Arduino IDE. So I cleaned some out.
What I want to end up with is a simple list of devices I need.
My board = Uno
Devices I want to use (and load bootloaders on) = Atmega 48v running at 10mhz, 88, 168 and 328.
Method = breadboard with crystal connected to Uno board.
From what I can read this should not be hard to do (with all the work you and others have already done)
All I need is a guiding hand to help me put it all together.
Thanks for your time guys!
