First experience with 6510

My first test of the 6510 was successful.
I connected the 8500 (HMOS 6510) to an eprom, a 555-clock-circuit (right) and a transistor with an LED at the I/O-port.
The first small assembler-loop (written on my C64 with HES-Mon) flashed the LED very fast (without delay) ;-)

You see Phi from the 555 and the I/O-port on the Hameg HM-512:
