I found this.  Run from BASIC using whichever DOS you have...

X=PEEK(978) Determines where DOS is - if less than 157 then DOS is below
   normal location - computer has less than 48K memory; if 157
   then DOS is at its normal 48K location; if 190 then DOS is
   ProDOS, not DOS 3.3; if greater than 190 then DOS is in the
   language card.

Another source says this PEEK can show memory
   size if used as: PRINT (PEEK(978)+35)/4;"K"
