The fifth and final video in my #SEPTandy series, BIG-ly Tandy. Using my TRS-80 Model 16B, I connect the (recently-restored) 8-inch floppy drive and make real disk copies of today's application: Teleterm. Then, we boot from my real disk and explore a little of Teleterm's functionality including the terminal, text editor, and terminal emulation editor. Using Terminal, I connect to FozzTexx's Level29 BBS and print a portion of my session.
Update - Around 9 minutes in, I mention the orientation of the label when inserting a disk, incorrectly stating the diskettes are why the label must face the operator. I meant to say big Tandy machines other than the Model II require the label to face the operator.

![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!

![TRS-80 Model 4 Hi-Res Graphics Upgrade
My TRS-80 Model 4 gets even better with high-resolution graphics! I install Ian Mavrics Improved Grafyx 4.2(.1) HRG board, which is his reproduction of the MicroLabs Grafyx board from the 1980s. After installation, I test some high-resolution software including Post Master, a Slot machine program, and some Graphics BASIC programs. I swear a little more than usual in this video...
