My first linux system, roto-router, was an IBM PS/2; a 486 that I upgraded to have a math coprocessor, 32MB of RAM, and a 1G hard disk. The system has been kicking around and still boots, but its only a matter of time before the 13 year old hardware gives up the ghost…
So, thanks to virtualization and some common unix tools…
Roto-Router is running in Parallels on my intel mac.
I did recompile the kernel to get the ethernet interface detected (old card was an isa ne2000, parallels uses a realtek 8029), removed an append line from lilo.conf, and I set eth0 to dhcp. Otherwise, its untouched.
