Many users have received notices telling them that they must upgrade to Rev. H
CPU ROMs to run Pascal 3.0. THAT NOTICE WAS IN ERROR! Acceptable ROM versions
include:

Lisa 2: D/A8 or H/A8
Lisa 2/10: F/88 or H/88

–The first (alphabet) character indicates the revision of the CPU ROM; the
following two characters identify the I/O ROM.

Other CPU ROM versions, such as A, B, C, E and G, should definitely be
upgraded. If a user insists on Rev. H CPU ROMs, or if you need to upgrade old
CPU or I/O ROMs, order them from your Apple Regional Service Center. The part
numbers are:
CPU ROMs I/O ROM
Lisa 2: 341-0175, 341-0176 341-0290
Lisa 2/10: 341-0175, 341-0176 341-0281

NOTE: The ROM versions are both stamped on the chip itself and displayed in
the upper right corner of the Lisa’s screen when you boot the system.
