[Simh] PDP11 on Simh for public access

[Bryan Davies]

It works!  Many thanks to all who have assisted.

I installed the changed .ini file and sure enough I now get past the
startup prompts.

Paul - I have kept the modded Init.sys on standby but haven't installed it.

My only comment is that Simh seems to be very heavy on CPU.  The Raspberry
Pi seems to be maxed out when running it - even when the simulated OS isn't
'doing' anything.  But it is nevertheless good enough for display
purposes.  I will be installing it at http://www.computinghistory.org.uk/
tomorrow and the PC / Smartphone generation will be able to see how
computing was in the 'olden days'.


Regards to all,

Bryan.
