When PCjs hit the front page a couple weeks back I noticed VAX was conspicuously missing and couldn't resist seeing VMS run in a web browser. Claude Code running Opus 5 meticulously ported the KA655 from SIMH to PCjs.

It boots up to OpenVMS 7.3. I demo with 5.5 because its 1/10 the size and hits the nostalgia even harder.
