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 ftp.cs.umb.edu, currently at IP address 192.12.26.23. 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. --Betty O'Neil eoneil@cs.umb.edu, also eoneil@bbn.com
