The same boot ROMs recommended for Lisa software are fine for systems running
MacWorks. In addition, square pixel ROMs are available for systems running
only MacWorks XL. They are:
SYSTEM CPU I/O Sq PIXELS (CPU-I/O is the same)
Lisa 2/10-Mac XL F, H D (88) A3
Lisa 2 D, H B (A8) A3
Although MacWorks has been thoroughly tested with the earlier ROMs, consider
upgrading them if a system with earlier ROMs shows illogical errors, such as
locked disk errors when initializing a disk, which may occur after loading new
system files.
