Hi

as written previously, I don't think this is related to TT RAM. ST RAM 
detection will fail with high vdi resolution even if you use 14 MB RAM 
and no TT RAM.
In all cases, memtop and phystop ($42e and $436) are limited to ST RAM 
space, if you have TT RAM, it's only refered in $5A4. So the "gap" 
between memtop and phystop should be ST RAM related.
