C64 "Screensaver"

A Commodore BASIC demo, a genuine reset and a useless human typing the commands as explained here:

[traceyrmj2]

POKE YOU SYS 864;656

[phodd]

@traceyrmj2 ?SYNTAX  ERROR

[jjovereats]

@phodd I am the new traceyrmj2, same boy, different name: POKE 899,222:sys899

[phodd]

@jjovereats .. this makes no sense. you're setting 899, which is in the middle of the cassette buffer, to the DEC,X opcode .. but the rest of the buffer is zero, as is the X register location at 781 decimal.. meaning you execute DEC $0000,0 (reduce the value of location 0+0 by one)... the next instruction is also a zero, which is a BRK, which resets the 64 to some degree, including location 0. What was your objective?

im using an emulator and did exactly what you said, i typed it in correctly and it worked but it showed to question marks. Any help?

[phodd]

@hamstermadness549 - sounds like your emulator either doesn't have a true C64 ROM, the RUN/STOP+Restore isn't working or clearing the screen properly, or you've mistyped the POKE and SYS. Try POKE2,0:SYS2 (press enter) instead of the R/S+Restore (it does effectively the same thing) then try the POKE781,96:SYS58251 shown in the video.

yes, ladies and gentlemen, this is bound to "save your screens", be they TFTs or CRTs. run this 5 minutes a day at morning, and again at evening, and your screen's longevity will increase manyfold.

[jjovereats]

@phodd If you do PRINT CHR$(147) and put the cursor at the ready prompt, then type it (POKE781,96:sys58251), goes as normal. :-)

[hamstermadness549]

@phodd alright thanks. ill try it now and if it dosent work ill just PM you.
