If you ever wanted to simulate a Burroughs 220 vacuum tube computer on your Apple II, rejoice! Those lucky enough to be at KansasFest this past July had the opportunity to check out Michael J. Mahon’s preliminary work on his B220SIM. Functional but limited at the time, B220SIM aimed to show off the state of the computing art, circa 1955. Now, Mahon has announced that his simulator is nearly complete and you can try out the fruit of his programming labor at his website.
