Born Again Disclaimer:
Born Again, from Brochner Software, is software that permits installing OS 8 or 8.1 on 68030 Macs with 32 bit clean ROMS.
We in no way used Born Again to install OS 8 or OS 8.1 on our 68030 Macs.
We never looked at any code from Born Again.
We got the trial version from the author and tried it once to unsuccessfully install OS 8.1 on an SE/30 with IIsi ROM simm.
