Over the years I've snagged a few domains related to classic computing with the best intentions of doing something with them. I have not, so I will be letting the following expire:
decvax.org dgeclipse.org dgnova.org hp1000.org hp2000.org pdp11.org rt-11.org You can of course wait to get them until they expire via your registrar of choice. If you want them sooner, let me know and after a week or so I'll subjectively decide who to approve a transfer to their registrar. Best, J
