Yes. Thank you for reminding me that web emulators already exist. With
some googling I found this one:

Yes, agree. The main emulation is 2,000 lines of JS, the I/O devices are 1,500 lines.
That's quite manageable for making a few changes.
Hopefully I will have some time later this year to add 'direct run' emulations
to the TUHS site based on this code (assuming Warren agrees). The idea would be that next
to Archive and the Tree there would be emulation. A visitor would go to e.g. the V5 page
of the Tree and also find a link to run V5 in emulation. From the SIMH and Nankervis sites
images for:
- V5
- V6
- V7
- 2.9BSD
- 2.11BSD
appear to be already available (but the SIMH images may include devices not supported by
the current Nankervis code). I'm not quite sure if and how networking could be
enabled for 2.9BSD and 2.11BSD - at least the network card would need to be emulated and
somehow translated to web socket connections. Same goes for adding live UUCP emulation to
the V7 demo or live Arpanet emulation to a future NCP Unix demo.
