+---------------

Tandy 16/6000 series can only address 1MB presently due to a brain-damaged
MMU (recent hardware mod, hopefully soon to be released, raises that to 4MB
at the expense of having larger memory segments); however, it's capable of
*physical* addressing 7MB.  So the Wizard of TRS (aka Bob Snapp) sells a
6MB RAM board and ramdisk software for it....
