memory question

[Lee Sailer]

I am running a 6300+ with Unix V.2 (v. 2.0) and Simultask.  I have a simple
question about the memory messages at startup.  Mine say:

real mem  1572864
total mem  1220608
actual mem  654848

I know I have 1.5MB.  Where does it all go so that I only have 654848
"available".  I don't have any spiffy devices installed or anything, and
am mostly a single user system.  Is there someway I can free some kernel
memory or something to get a few more K of user memory?

Thanks.  Email appreciated.
