>Has he though? Yes. ROM-booting was something Apple supported in the Mac Classic and no other model. The ROM adds new functionality that wasn't available to the SE/30 (and others). It also adds the ability to boot of a modifiable RAM disk, which is new. Also it's 32 bit clean, unlike Apple's ROMs. So this fixes Apple's bugs as well as adding new abilities to a few models of Macs that they never had. The ROM-booting is facilitated by compression, but putting together a bootable ROM for hardware that's never done it before to ROM-boot off the compressed system image is the hard part, not the compression. Much of that is based on the hard work of Rob Braun, Doug Brown, and others who are credited. He put a lot of work into this, the thing he made wasn't an existent thing in the world until he did the labor and he documented how to do it for those who want to burn their own. He ships a ROM SIMM with the new image burned on it for $45, given that the ROM SIMM itself isn't free, the whole deal seems fair to me. The creator has also been involved in Floppy Emu. He's done a ton to help revitalize retrocomputing. Begrudging him selling a ROM image he worked to make is an incredibly toxic take on a person doing really excellent things and sharing the technical details for anyone who want to build the stuff themselves.
