Bizarre coding tricks
Just a curiouso, but I remember coding a LED trick that, using timers, made the LED fade out, rather than switch off. (This don't work in WinUAE
![]() I also made some code to do the same thing with the drive light, although people might not like it on real hardware, as this was a bit hectic on the drive motor. Thing is, I also remember some coding trick where someone did a routine to play 1 channel music on the drive stepper motor.. anyone else remember this? Today, I found out about the c64 demo where you have to "lick" the joystick port ![]() Anyone know of any similar outlandish hardware coding tricks from the old days? Would be interesting! |

Years ago during a hardware, academic project, I inquired if there was a way to turn the Caps Lock LED on/off via software.
However, Andy Finkel had an interesting insight to the A1000 design... Quote:

Spook of Digital used the CAPS Lock led trick on The Punisher demo, alas because of this, it crashed on A12oo's.
I do remember some buffoon magazine reviewer commenting on piracy, and how all cracked games had viruses, and that sometimes the 'stupid' crackers would 'screw around' with the Power LED whilst a game was decrunching, and they were clearly 'banging the hardware'! Dullard... it was also the Audio filter! |
