I hope I know the answer, but having said that, I’m really curious as to why they’re working on the emulation.

The only old Lasers I have are an HP 5mp I bought new, and finally retired this spring (though I just realized it’s probably still on), and a 5p I was given a few years ago.  I was quite happy to get my VMS Cluster working with a modern HP LaserJet that is *WAY* faster, and supports duplexing.
