Lisa and Macintosh XL: Memory and Hard Disk Requirements

Lisa Office System:
Hard Disk: Office Systems 1.0, 1.2, 1.4, 2.0, 3.0, and 3.1 all require you
to use at least a 5-megabyte hard disk.

Memory: Only Lisa 7/7 Version 3.1 will run with 1/2 megabyte of memory.
All previous versions of the Office System require 1 megabyte of
memory. If you're using Version 3.1, we highly recommend that
you use a full megabyte of memory in order to improve system
performance.

Workshop:

Hard Disk: Within certain limitations, you can operate Lisa Pascal
Workshop 1.2 without a hard disk; we recommend that you use
one, though, unless you aren't concerned about system
performance. All subsequent versions of the Workshop require at
least a 1/2-megabyte hard disk.

Memory: All versions of the Workshop require 1 megabyte of memory.
Versions 1.2 and 2.0 appear to offer you, in the Preferences
window, an option to run them with only 1/2 megabyte. If you
choose this option, though, the system will hang if you then try
to access either the Editor or Preferences.

MacWorks:

Hard Disk: MacWorks Versions B and later do not require a hard disk,
though those versions will support one. If you opt not to use a
hard disk, the system will simply behave like a Macintosh
without an external drive.

Memory: All versions of MacWorks can run with either 1/2 or 1 megabyte of
memory.
