Nibble. It allows plot to the SHR screen from Applesoft. I only wanted
it to initialize the SHR screen and turn on and off the display.

I then installed &POKE from the Beagle Bros Extra K disk. Disconnecting
the /RAM drive like advised.

I'm able to &POKE values into the AUX mem, and it shadows to the SHR
screen and works great....except. It does not work &Pokeing to screen
lines over 102 or 103, decimals 24512 and above. According to &PEEK the
value is there in memory, it just doesn't show up on the screen. Can't
really figure it out.....

This works as expected, for me, under MAME:

10 & hgr
20 for i=0 to 31999
30 c=rnd(1)*255
40 &poke 8192+i,c
50 next i
60 get x$
70 &text
80 end

Does not work with GSplus v0.14.

I'll have to try some other emulators.
