IBM 360 emulator counting up

This IBM 360 model 65 console panel is hooked up to a - very incomplete - emulator running the IBM 7201-02 microprogram. See http://ibm360-console.blogspot.com.

The program being executed:

000030: 1A 01 AR R0,R1 Add R1(1) to R0 
000032: 47 F0 00 30 BC F,30 Branch unconditionally to 000030

(This is about all the emulator can do right now, but it proved the principles are correct).
