Quite interesting stuff as usual
Kind of makes me wonder why many early processors had no ABS instruction, though. |

Now is right and nice
I don't think it's a problem for buzzybe the limited +/-16384 range, nor the inverted x/y input. |

neg, use it!". I could understand for a 'simple' processor (RISC or with PLA or with only state machine/combinational logic), but not for a micro/nano-coded one like the 68k.. So yes, ABS is a missed instruction. |

Guys, you are amazing. Following this conversation feels almost like a rap battle to me - with all results having their own flavor.
@ross: You are the god of efficient code. Your skills are so inspiring. @robinsonb5, I can absolutely tolerate the limited range and the inverted result. Just tested your code, works perfectly as a controller of Kraken attack wave animation frames. Will make them look amazing. |

LOL - that will probably be the one and only occasion in my entire life when I'm likened to a rapper! Quote:
Glad to hear it worked out - thanks for a fun puzzle! |
