Cleaning house! I have a DEC Alpha XL300 system I'm not using. This is one of the Alpha systems that was crippled so that it could only run Windows NT (no SRM firmware, AlphaBIOS only). There used to be a kludge to run Linux on it, but I think support for that has long since gone away.
It's cosmetically clean, and I even have the key for the case so you don't have to break the lock. I have Windows NT 4.0 installation media, and can probably dig up a period correct keyboard and mouse. A VRT17-HA CRT monitor in good condition is also available to go with this. It worked the last time I tried it. Free for local pickup. I'm willing to drive a reasonable distance in the Seattle/Eastside area to meet up.
