- anigbrowl 14y agoGood catch and well worth reading. I thought there was something familiar about the link but oddly HN didn't refer me back to the earlier thread.
- jacquesm 14y agoHN will never refer you to an earlier thread unless the URL matches exactly. See the '/index.html' suffix on the original and the lack thereof on this one, that's the difference that allowed you to submit the URL for a second time.
- spullara 14y agoIt is awesome though, I enjoyed it the first time, and apparently no one saw it because it is now at the top of HN.
- jacquesm 14y agoYes, it is awesome. When I learned how to program 6502 asm the best you could do was to buy Lance Leventhal's book and cobble together your own assembler, now you can learn the same thing interactively in a browser. 30 years difference.
- sageikosa 14y agoMachine code monitor on the Apple ][+...had to calculate jump offsets in my head.
- spullara 14y agoOn the C64 I had the monitor cartridge. Always great when you had to block move memory to add an instruction in the middle. Converting things to data statements was also fun.
- sageikosa 14y agoDid some of that, had to throw in delay loops so the sprites wouldn't tear when moving in response to the joystick.
