Assuming that Suitcase (or work-alike) is reasonably stable in your configuration of hardware and software, and that you can keep Fonts, DAs, and FKeys in separate files/folders - I'd prefer to keep my System as small as possible.... or am I overlooking something? I've always kept a set of 400k disks handy, filled with the latest, to help out the "underpriviledged" ..(-: and, YES, I have a 400k-Boot-disk with OS Version 6.0 .... I haven't tried it, I admit, but using a RAMdisk-creating StartUp-application gets me up and running (I expect) with the 2Meg RAM I'd rather have than an 800k drive... Here is how I'd go about it. On your 400k Boot disk put the following: System (minimum Fonts and DAs) - remove unnecessary resources. RamStart+ (or similar) - make that the StartUp to create RAMdisk and eject floppy after copying OS to RAM and continuing execution from there. SuitCase - to enable dynamic loading of DAs, Fonts, Fkeys. other-INITs - INITs must be loaded at Boot-time!! MiniFinder or SkipFinder or similar alternative - most other stuff (including CDEVs) can be loaded to the RAMdisk from floppy later; INITs *HAVE TO BE* available when booting the Mac!!! I probably forgot to mention a few things and made some assumptions which may not be correct - but then I admit not having had the time to try out what works with 6.0 from a 400k floppy and what doesn't; but with 2Meg or more of RAM, I'm confident that it is possible to get many of the HUGE applications even (Hypercard et al) to an executable state - not that I'd want to have to do it, you understand, but .... most applications are not that large, anyway. Besides, I seem to remember that I once used a Mac512 souped up to 4Meg RAM and dual 680x0, 400k floppy and, sometimes, a hard disk connected to the serial port ...... or was that a BAD DREAM? it seemed quite wonderful then, especially, with a recoverable RAMdisk ....and not having to COLD-boot very often ....

Yes...and the correct 128k roms on the motherboard. You'll need a new back as
well, to accomodate the changes in prt configurations.
