Daves Old Computers - Simulators and Emulators

"Those to can, do - those who can't, simulate"

Here are a number of simulators that I have found. I have tried to locate simulators for all of my machines which are simple and straightforward to use. I have not yet found simulators for some of the machines, and there are a few some here for which I don't have a corresponding physical computer. In a few cases, I have written my own simulation because I know no other simulator will be suitable.
