It must be a documentation error. The whole time I've been on this list,
since some time half way between 1.0 and 1.1, you've needed a PMMU. It was
in the FAQ (I thought)...

Yes. And A/UX requred it too. The protective actions UNIX takes to keep
prograoms from crashing the computer (just themselves) require an MMU.

No, but I'd wonder if it's worth it. If you get rid of MacOS, you can fit
a good chunk of the OS into that drive. But you'd be cramped.

I'd suggest getting another disk drive. In the US, drives are going for ~
1GB/$100US. Even if you can't afford a new one, I bet you can find someone
who wants to upgrade his or her disk, and buy the old one. I have fit most
of the instalation (minus timezones, and the webster dictionary) and X
into a 100 MB drive. I needed more space to _do_ much else, but 100 MB was
a good start.

Also, since SCSI can handle multiple drives, if you can find multiple
retired machines, you can build up a nicely-sized machine. 3 or 4 80 MB
drives will certainly have you on the way to a nicely-featured (though
slow)  machine. :-)=20

Take care,
