yay!

[dented42]

lets see...
I type 'monitor' to enter the builtin monitor
type:
a 01300 lda $47
a 01302 jsr $ffd2
a 01305 rts
x

I get a ready prompt and type in:
sys dec("1300")
G
and a g appears on the screen.
YAY! mind you I was expecting an A, but I'm not complaining

Since you started a new thread, I don't know if you were following my example or not...

But you have two mistakes in that one line. It should be
a 01300 lda #$41
The # is important - it means that you want to load the value $41 into the accumulator, rather than the value in location $41. If you got a G displayed, then you probably did a lda #$47, but didn't type the # in when you posted here.
