There's a bug, but it's in your code. In the 'write' callback you should save and restore D2 and D3. Also copying the byte in D0 directly to the top of stack isn't a good idea because it splats over the current contents. In your code this is the (long) saved contents of D0, which luckily doesn't matter because D0 doesn't need to be preserved.

I changed your code to this:-

Code:
write:
        movem.l d2-d3/a6,-(sp)
        movem.l (a3),d1/a6
        move.b  d0,-(sp)
        move.l  sp,d2
        moveq   #1,d3
        jsr     -48(a6)                 ; Write next character to stdout
        move.b  (sp)+,d0
        movem.l (sp)+,d2-d3/a6
        rts
and it printed properly in WB1.3 on my A500 (previously it would print a 'random' character several thousand times before doing the second number).

Still got the wrong hex result though... must investigate further!
