Does anyone out in netland know how to modify DOS 2.5 to allow it to see
the additional 128k RAM when you add any of the four 256k RAM expansion
boards to an 800XL or 1200XL?  (I realize that  only one of the boards
will work with the 1200XL, and I do not remember all of the brand names --
CDY, Byte, Newman (?) and ??.)  The point is that I do not like SpartaDOS
or MYDOS and would like to be able to upgrade my 800XL, 1200XL and 130XE
all to 256k with DOS 2.5 compatibility.  By converting them with the latest
board (brand name ???) I can use DOS 2.5, but it will only see 128k RAM,
the other 128k beilng invisible.  Neil Harris or others at Atari, are you
listening?  We would like to be able to upgrade all Ataris to 256k (includ-
ing the 130XE) and have the DOS 2.5 (or DOS 2.6??) see all of the memory.
Also have Atari Writer + see all of the 256k RAM.  Any suggestions from
Atari Corp or from hackerland?

Thanks in advance,
--Bill--
