SWTPC Retro DIY sound card.

Making a vintage computer from 1975 speak using resistors and things. I repaired my SWTPC 6800 so now is the time to have some fun with it. In this video I discover how to build a retro sound card using a digital to analog convertor (DAC) built using a simple 2R-R resister ladder. Building the card was pretty easy compared to writing the M6800 assembler to make it speak!!
