These two things will probably be necessary.  At least the use of the 6K
area will be needed at some point.  Perhaps some sort of compression of
room descriptions would be in order.  For example, every room has a list
of pointers in it.... this pointer is possibly multiplied by 2 or 4 so we
have 512 or 1024 bytes of text data instead of 256, and added to the 
location of the REAL lines of text:

This example will not use multiplication, but....

ROOM1	.byte YouHave,ReachedA,DeadEnd
ROOM2   .byte YouHave,FallenInto,AHugeHole

TextData .byte lY,lO,lU,sp,lH,lA,lV,lE,eol
X1       .byte lF,lA,lL,lL,lE,lN,sp,lI,lN,lT,lO,eol
X2       .byte lA,sp,lH,lU,lG,lE,sp,lH,lO,lL,lE,eol
X3       .byte lR,lE,lA,lC,lH,lE,lD,sp,lA,eol
X4       .byte lD,lE,lA,lD,sp,lE,lN,lD,eol

YouHave = 0
FallenInto = X1-TextData
AHugeHole = X2-TextData
ReachedA = X3-TextData
DeadEnd = X4-TextData

I made some assumptions about how the values of the letters are represented.

And background music doesn't?
