Printing from a SPHERE with a SWTPC PR-40. Vintage Peripherals with Peddle's PIA!

Technical and historical dive into Southwest Technical's amazing little 1976 PR-40 Printer, and how it can be connected to a Sphere computer (or any vintage computer!) using Motorola's magical 6820 PIA chip. We look at how this special peripheral and its parallel interface works. We connect the hardware and trigger the printer using only a live debugger, before using real diagnostics and demonstrating a small word processor text editor for Sphere that has been updated to allow printing. Come along for the adventure!
