The following item just appeared in comp.archives.  Since I don't recall
having seen any prior mention of it here in comp.sys.3b1, I've reposted it.

Anyone know what this means?  Mt. Xinu sources for the 3B1???  (And, yes,
I know that ``Mt. Xinu'' is ``UNIX (tm)'' reversed end-for-end :-)

| A few weeks ago I wrote about about my port of Xinu Vol. I
| to ATT7300s, aka 3B1s or UNIX PCs.  Doug Comer answered the
| important question right away, saying it is fine to distribute
| it via anonymous ftp, so natually I had to then find time while
| giving finals, etc., to actually clean it up into presentable
| form.  I have now done that, and a README and a tar of the
| usual distribution tree is available in ~ftp/pub/xinu7300
| on host, currently at IP address
| There is both the Xinu port and the software needed to run
| from the 7300's floppy disk to download and provide a debugging
| monitor for running/modifying Xinu.  The distributed Xinu sources
| themselves are as close to the original as possible.
| These ATT7300 systems make great Xinu engines.  They come with
| at least 512K of memory, usually 1M, a MC68010, a simple paging
| system, and serial and parallel ports.  The hard disk burns
| out easily, but as long as the floppy still works to boot the
| standalone debugger/downloader you can run Xinu; the rest of
| the system seems quite sturdy.
