RSTS emulation in a browser

[John Foust]

Back in 2000, Jay Jaeger generously helped me read some old backup tapes 
from a RSTS V7.0-07 system.

I'm not sure why I hadn't tried before, but I recently thought I could 
try to run those circa-1982 BASIC-PLUS and FORTRAN programs under emulation.  
And maybe even in a browser.  There's a JavaScript emulator at:

https://skn.noip.me/pdp11/pdp11.html 

I can 'boot rl2' on that web site and it runs, but when I try to
run it locally in a browser, it hangs.

Am I missing something simple?
