Robert Bowdidge, one of three interns at Berkeley Softworks who ported GEOS to the Apple II is interviewed by Mike and Quinn, talking about what a great place Berkeley Softworks was, along with the power of good tools and proper software engineering. Robert has great memories of the culture there, the GUI technology they had built, and the brilliant people who built it. Apparently GEOS existed for some other 8-bit computer as well.
The podcast hosts even offer this month a special GEOS image to be downloaded.
