I also realize that the 4917 cannot do arithmetic involving any numbers larger than 15, be it the inputs or the outputs, but instead resolves to clock arithmetic e.g. 15=15, 16=0, 17=1 and so on. Could someone verify this please?
Thanks
However, I do find it sort of strange that the emulator being used doesn’t do the same with negative numbers to negative infinity.

I’m completely new to this. Probably an A person by definition of Buckland. But I feel that both addition and if programs can be optimized.
Addition
9,14,10,15,1,11,8,8,0,7,0,0,0,0,0,0
and the Beep program
9,15,11,5,8,0,14,9,0,7,0,0,0,0,0,0,0
Both of them definitely leave out more free memory locations, which in turn could store more beeps that never happen
Would somebody mind checking this?
Thankee

This is not education in machine code , this is basic electronics.

This wasted an hour of my life.

I prefer a road runner effect, beep – math – beep – print – beep
7.9.14.10
13.1.11.15
7.8.15.7
0.3.10.13

This is really great. I’m been wanting to learn this stuff for awhile now and these lectures are really helping. I really like how Richard speaks with such passion, confidence and humour.

9 2 10 15 1 11 14 7 8 14 7 0 0 0 0 3

that does the maths and also beeps twice

or you can make it beep five times with

9 2 10 15 1 11 14 7 8 14 7 7 7 7 0 3

or on an infinite loop with

9 2 10 15 1 11 14 7 8 14 7 13 10 0 0 3

which is even better

9-13-10-14-1-11-15-7-11-11-8-0-0-3-10-0. Change this to:
9-13-10-14-1-11-15-7-11-11-8-0-13-3-10-0.
Now it produces (much more than) two beeps.
