The next Mac 512K Blog article will talk about RAM disks and disk cache utilities. If anyone reading this blog has MacXINU or Aztec C, please get in touch with me by email (find my address at the end of this article) or by posting a comment!

I will finish this blog article with an excerpt from MacXINU's documentation. So this adventure in alternative operating systems has come to a premature close.

It will boot on my 64K Mac 512K, but does not have enough memory to load completely. MacMINIX on the other hand will run on a Macintosh Plus with 1 MB of RAM (but we can't talk about that because this is the Mac 512K blog, not the Mac Plus blog). Furthermore, I have no copy of Aztec C for Macintosh, nor can I locate any copy. Unfortunately, the Macintosh XINU archive on Mac GUI Vault seems to be incomplete, and has no application to launch. All these alternative operating systems ran as a regular Macintosh application they did not take over the entire Macintosh hardware. Both Macintosh XINU and MacMINIX used the Aztec C compiler. There was a CP/M environment by IQ Software, as well as a few Unix-like systems, such as Douglas Comer's XINU, ported to Mac by Steven Munson, and a port of Andy Tannenbaum's MINIX. It only took a few years for alternative operating systems to become available for Macintosh.
