Running Simulators from teenix.org on virtual machine?

[Thomas Okken]

I tried running the HP-25, 19C, and 97. Basic operation was OK with all three, but the 19C crashed when I tried to run a program on it: the display went dark and it stopped responding to the keyboard. Toggling the ON/PRGM/RUN switch made the display come back on, but showing nonsense. No way for me to say if this is a bug in the emulator or a side effect from running in a VM.

Also, the print-head moves slower than the sound, so you hear it make the high-pitched "carriage return" sound while it's still printing the line.
