At the moment the best place to get hal91 is through the web-site, http://home.sol.no/~okolaas/ut hopefully I will get some ftp mirrors quite soon. When downloading please avoid using Netscape 4.0x, as it is known misinterprent downloading files from the web-server.
dd if=hal91.img of=/dev/fd0
rawrite hal91.img a:
There is a datadisk lying around since a former version of hal91 this disk should also work with 0.2.0 just type init.disk2 and you should get a new ramdisk mounted under /usr/ with programs like lynx, irc, mc, cfdisk...
