555 Am Transmitter Circuit Diagrams?

I have two ICM7555 CMOS 555 timers, and I was wondering if anyone has any good am radio transmitter circuits that incorporate two (or one!) 555 timers.?

You do have to be careful what version of the 555 you use but any of the newer types should be ok. Early ones are too slow to work in the am band.
Here's a quick schematic I threw together to show how to really amplitude modulate a 555. Lots of calculators online to figure out values so I didn't bother.

Intersil's 7555 timer is way too slow to generate an AM frequency
sorry there are no circuit diagrams for AM using this part.
