stick QNX on it and watch that old thing fly
agreed, If I remember corredtly, I was able to put Neutrino (qnx4) onto one (bootable) 1.44MB floppy disk and it ran a web browser and a web server in that small footprint.
As a plus its RTOS , therefore swift and agile.
{caveat}=Momentics (qnx6) doesnt like my netcard. ;{
