The Save-It Card: Exploring 513 Part V

Part five of my series exploring the Memorex VIS. In this video, I take a closer look at the Save-It cartridge. We'll walk through what it is, how it works, and how to utilize it using Microsoft-provided libraries. I then use one of the rare Tandy VIS developer expansion cards in my Tandy 4833 LX/T to create my own custom bootable Save-It cartridge and run an on the VIS from the card for the first time since 1992.
