Aptrex / Entria X Terminal boot images
Aptrex / Entria X Terminal boot images
These were hard to find even back in '98 when I picked up a couple of HP X Terminals at Weird Stuff. I don't have the boxes any more but if you do, you'll need these boot images. I think they're grabbed via tftp.
I used one of these as my primary "desktop" for about a year as it was completely silent.
More information on these at Brian McElroy's HP X-Terminals page and also at openpa.net.
