This video is an overview of the network configuration of my Tandy 1000 SX. We'll take a look at the card itself (a Racal Interlan NI5210) as well the configuration of the packet driver and mTCP. Then we'll put it to use getting files from my Raspberry Pi and starting an HTTP server on the Tandy 1000.
Finally, I have a couple of updates on the Tandy 1000 RLX, so I share them here. Windows 3.1 now has audio support with the Tandy DAC driver, true-type fonts were disabled in Windows, and I used Cloudschatze's 0-wait-state driver to speed things up.

![Top-Tier Tandy CoCo 1987-Style: Just Add A Hard Drive
What would a hard disk-enabled Color Computer 3 dream system look like in 1987? What hardware is required? How is it set up? I answer all of these questions and more with a deep dive into one of Tandys rare peripherals for the CoCo: The Tandy Color Computer Hard Disk Controller. Ill build a high-end (and expensive) CoCo system, complete with a virtual trip to Radio Shack. Then we put it all together and configure the OS-9 operating system to use the hard disk. I demonstrate OS-9 configuration and bootfile customization and software installation. I then add a DT-100 terminal for more flexibility before we finish out by removing all of the disks and starting OS-9 from a CCR-81 cassette recorder. Its a CoCo storage extravaganza!
