AVR Freaks

For some reason I can't find the NXP RT1062 chip for sale. But I found the RT1064 which should be similar, it costs <10€. Impressive for something as powerful as a mid 90s era CPU by my guesstimates.

I have Teeeny3.2 which has excellent performance.
Teensy3.5 and Teensy3.6 are even better. (but I do not own either)
.
This Teensy4.0 is dramatic. I might even buy one for myself.

Gee, now if it only came with a Basic compiler...
