Nice. What will be your next project?

[Jacob Roman]

My first NES program done in 6502 assembly

  .inesprg 1   ; 1x 16KB PRG code
  .ineschr 1   ; 1x  8KB CHR data
  .inesmap 0   ; mapper 0 = NROM, no bank swapping
  .inesmir 1   ; background mirroring
  

;;;;;;;;;;;;;;;

    
  .bank 0
  .org $C000 
RESET:
  SEI          ; disable IRQs
  CLD          ; disable decimal mode
  LDX #$40
  STX $4017    ; disable APU frame IRQ
  LDX #$FF
  TXS          ; Set up stack
  INX          ; now X = 0
  STX $2000    ; disable NMI
  STX $2001    ; disable rendering
  STX $4010    ; disable DMC IRQs

vblankwait1:       ; First wait for vblank to make sure PPU is ready
  BIT $2002
  BPL vblankwait1

clrmem:
  LDA #$00
  STA $0000, x
  STA $0100, x
  STA $0200, x
  STA $0400, x
  STA $0500, x
  STA $0600, x
  STA $0700, x
  LDA #$FE
  STA $0300, x
  INX
  BNE clrmem
   
vblankwait2:      ; Second wait for vblank, PPU is ready after this
  BIT $2002
  BPL vblankwait2


  LDA #%10000000   ;intensify blues
  STA $2001

Forever:
  JMP Forever     ;jump back to Forever, infinite loop
  
 

NMI:
  RTI
 
;;;;;;;;;;;;;;  
  
  
  
  .bank 1
  .org $FFFA     ;first of the three vectors starts here
  .dw NMI        ;when an NMI happens (once per frame if enabled) the 
                   ;processor will jump to the label NMI:
  .dw RESET      ;when the processor first turns on or is reset, it will jump
                   ;to the label RESET:
  .dw 0          ;external interrupt IRQ is not used in this tutorial
  
  
;;;;;;;;;;;;;;  
  
  
  .bank 2
  .org $0000
  .incbin "mario.chr"   ;includes 8KB graphics file from SMB1

It just makes a blue background but it freaking works

My first program that made it big:

print "Hello World";

I was about 6 years old 1989 and the program was called pip i believe.

Repeat 100 million times. How long did that take to run in 1989. Seem's like it should still be going.

[Shaggy Hiker]

Back in those days, or even earlier, there weren't all that many computers on the market, and not all that much computer skill out there. However, all IBM PC and PC clones that came with DOS also came with some flavor of BASIC. So, I'd take the display model and write something like:

10 Print "Help, I'm trapped in a computer!"
20 Goto 10

and run it. As soon as the lines scrolled off the screen you'd think it would just look frozen, but since those screens tended to be pretty much crap in those days, it would flicker a bit as it sat there.

I figured that it would be a little test for the sales staff to see whether or not they knew enough about what they were selling to even stop a perpetual loop.

[FunkyDexter]

Easy. Unplug it.

Ha did not notice that.

Can't find this on Github!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Not open source!!!!!!!!!!!

Arduino!! Arduino!! Arduino!! Arduino!! Arduino!! Arduino!! Arduino!! Arduino!! Arduino!!

I saw where you spelled your name SaM. You need to go back to your 6 year old self and remind him about how important casing is, especially in C based languages! Just kidding, I love seeing old stuff like this.

[dilettante]

Github always sounds like a coffee shop for losers.

My first program was making a tree fractal using LOGO. AH that was many years ago and counting.

To think how the world has changed!

[wossname]

Every time I get stopped on the high street by a driver asking for directions, I find myself replying in LOGO commands.

"Ok, do a one-eighty right here, drive about 400 yards, take a left and then second right and uhh, ask someone else."
