A simple binary clock. that works on Windows XP console and DosBox emulator.
191 bytes, my code sucks, i know that.
But i'm learning..or at least i'm trying..Razz
Code:
    org 100h
    mov ax,0003h         ;clear screen 
 int 10h
     mov ax,0103h

 pop bx
      and bl,0fh

Nice job, thimis! I tweaked it for 8086 compatibility and added it to my FreeDOS disk #2. Smile

ok, it's pretty good, then, i decided to make it in fool 16bits.
Image
and it works. Very Happy

it compiles in 345 bytes, waste ~ 200 bytes, but is very modular and evolutive.

includes only the needed functions, and halts to save cpu time.


Description: fool for 16 bits, no call field, just needed datas.
