The makefile for KLH10 will build either a KL or a KS emulator, and Ken
supplied an ITS disk image (PI) for the KS emulator.

I use both SimH and KLH10 for Tops-10 and TOPS-20 debugging from time to time,
when I'm trying something that can crash the real hardware.  SimH is handy
because it runs natively on Windows (the office environment here), whereas I
have to run VMware Server on my desktop to run a Linux to run KLH10 and there
are times when the startup overhead is simply not worth the trouble.
