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.

This month on Open Apple, as is tradition, we present the megapodcast recorded live at KansasFest. Most of your favorite retrocomputing podcasters attend KansasFest each year, and we all get together in a basement room to record a giant group podcast. This year’s recording includes, in no particular order:

Quinn Dunki of Open Apple
Paul Hagstrom of Retrocomputing Roundtable and Drop /// Inches
Michael Mulhern and Carrington Vanston of Retrocomputing Roundtable
Kevin Savetz of Antic
Rob McMullen of Player/Missile
Ken Gagne of Polygamer and Indiesider
John Leake of RetroMacCast
Todd George of Chicken Lips Radio
Charles Mangin of How II
Jeff Salzman of The History Of Personal Computing

In this megapodcast, we talk about our experiences at this year’s KFest, and play a form of Liar’s Dice with each other’s personal computing histories.

A note on audio quality- it’s difficult to get 11 people recorded simultaneously in a room without a lot of fancy equipment that we can’t carry on airplanes, so we hope you’ll bear with us. We have a ton of fun recording these as a group, and we hope you enjoy listening to it. Many many thanks to Paul Hagstrom for doing the editing on this one!
