This is true, and this is how (in fact) we originally tested the first
few rounds of ROM 03, at least until preliminary hardware started coming in.
However, this causes problems (see below), _other_ than the fact that Apple
does not sell the ROMs without a CPU attached.

Once the preliminary hardware started arriving (with the new larger
keyboard micro controller, for example), we _stopped testing_ ROM 03
on ROM 01 IIgs hardware.  We can't offer any guarantees that programs or
(more likely) system software that identifies the ROM won't do hardware-
specific things they shouldn't do to your system.  ROM 03 not connected to
a 1 MB motherboard is totally unsupported, and if you use such a system
(of questionable legality anyway, given the inavailability of the ROMs)
you are operating completely at your own risk.

Ditto.

All ROM space is reserved for Apple and may not be used by third-party
developers for any reason.
