This INIT expands the unit table to 64 entries and relocates to high memory, out of the system heap. The original unit table is released, freeing a few precious bytes of system heap space.
Expanding the unit table from its original size of 32 (old ROMs) or 48 (new ROMs) means that more slots are available for drivers, including desk accessories. Installing desk accessories into these additional slots is your problem. ResEdit is one way; perhaps some non-Apple DA mover provides another.
The expansion is limited to 64 slots because of the format of resource numbers for "owned" resources: there are only six bits to designate the resource's owner. Still, sixteen additional DA's should be enough for anyone.
To use this INIT, assemble it, link it into a file of type 'INIT', and place the file in your system folder. It will be executed next time you start up your Mac.
