Launch Memo Editor (by pressing(8)): 15kB,plus the space needed for the text
document being opened (the first 1.5kB of the document doesn't require extra
RAM;it is "absorbed" in the 15kB of the program).

Launch Lotus 1-2-3 (by pressing (123)): 65kB, plus the space needed for the
spreadsheet being opened.

Launch the Calculator (by pressing E)): 24kB, plus the space needed for the

Launch the System Manager from the DOS prompt: 78kB, on top of the 18kB
used to boot DOS originally.
Now, each of the built-in applications—except for 1-2-3—must be able to load its
program code plus its currently opened data file into 64kB of memory. Thus, the
size limitations of single data files are:
*
.ABK files: 44kB
e Text files (for use by Memo Editor): 50kB
.PBKfiles: 47kB
»
.EB@Mfiles: 38 kB
e
.HK1 files: limited only by available system RAM
Allocating System RAM
Allocate as much memory to the system RAM as you can, without limiting your
internal RAM disk to too small a size. Until you generate enough data files to make
it unworkable, allocate about one third of the RAM to the disk and two thirds to
the system memory and (ifyou have a lot ofdata, consider getting a RAM card). To
change the allocation of memory between the RAM disk and system RAM:
1. Quit all applications except Setup. Remember to save any files that you've
changed since you last Quit.
2. Press (Slystem (Memory.
3. Press (q) or (») to change the allocation of the RAM between disk and system.
Notice that they move in 8kB increments.
4. Press
when you have the allocation you want.
5. Press
again to reboot the system (or
to cancel the changes.
