Boot the DOS system master and look at the page 3 vectors ($3D0-$3FF). They'll
be in the $9000 range for 48K, and in the $5000 range on 32K. Probably in the
$2000 range on 16K.

Any ProDOS from 1.1 up won't boot on 48K so use that to check for 64K.

I think popping the top and counting chips would be easier myself
