Here is an example of some of the first code I wrote.

Can you tell what each does and what kind of computer it might rub on.

Mystery Code 1: 

start    LDY #$FF    
loop1    LDX #$FF  
loop2    DEX       
    BNE loop2  
    DEY        
    BNE loop1  
    RTS

Mystery code 2: 
mlt16   LDA #$00     
        STA $26
        STA $27
        LDX #$16     
nxtbt   LSR $21      
        ROR $20
        BCC align    
        LDA $26      
        CLC
        ADC $22      
        STA $26      
        LDA $27      
        ADC $23      
align   ROR A        
        STA $27      
        ROR $26
        ROR $25
        ROR $24
        DEX          
        BNE nxtbt    
        RTS
