The Drop III Inches podcast returned this month with their first episode in 3 months. According to the posting on the Drop III Inches blog,
We’re back, with an episode that was three months in the making. Mike and Paul talk (in November 2016) about the state of things in our Apple /// worlds, and then speak at some length with Don Burtis (in December 2016), who designed (among many other things) the Microsoft SoftCard III.
Don Burtis, who is probably most prominently associated, in the eyes of the Apple II and III enthusiasts, as the designer of the Microsoft SoftCard, a Z80 coprocessor card that enabled the Apple II series computers to run CP/M software. As Paul Allen indicated in his book “Idea Man,” this was strategically important for Microsoft early on, as VisiCalc was beginning to take off on the Apple II for businesses, as it would allow Microsoft’s existing software to run on the platform without the delay and investment of porting the software to the 6502. Microsoft had a run at the project internally but was having trouble with the design, and Don Burtis (of Burtronix) was called in to design the board. And later, the SoftCard III for the Apple III, as well as several other peripheral cards for the Apple III (including the Floppycard III, Protocard III, Printercard III).
If you’re here just for the conversation with Don Burtis, it starts at minute 52.
