The Classes


TTT101

Title: Advanced Z-80 Programming

Instructor: George Phillips

Abstract: Give a general overview of where the Z-80 instruction set is fast and/or compact. Present a number of common micro-optimizations (e.g., XOR A for LD A,0) and some useful techniques for faster loops, memory copies and other common operations.


TTT102

Title: Model 100 Design and Repair

Instructor: Josh Malone

Abstract: The Tandy Model 100 family are common and accessible vintage computers and make great additions to Tandy collections. However, due to their unique RAM- and LCD-based design, newly-acquired units often exhibit common problems and require component-level repairs before they will function. Based on years of repairs and repeated questions from new owners, this session will cover the design details of the Model 100 family of portable computers (100, 102, 200, and some non-Tandy variants) and demonstrate the commonly needed repairs. It will also cover strategies for "field-testing" units before purchase, as well as basic accessories you will want to investigate once your unit is working.


TTT103

Title: 8" Tandy Repair, Upgrades and FreHD48

Instructors: Ian Mavric and Eric Dittman

Abstract:This course will focus on everything you need to know to get a Model II/12/16/16B/6000 up and running. It will also discuss modern upgrades including a special focus on the new FreHD48 hard drive emulator.


TTT104

Title: Tinkering with the TRS-80's I/O Bus

Instructor: Arno Puder

Abstract: The I/O Bus allows external devices to be connected to a TRS-80 computer. Examples are the popular FreHD that simulates an external hard disk or TRS-IO that adds general I/O capabilities such as networking to a TRS-80 machine. This workshop will explain the functionality of the I/O Bus and how to use off-the-shelf integrated circuits to create a simple I/O device that can be connected to a TRS-80. We will provide a crash course in TTL logic and how to use a logic analyzer to debug your design. To round things up, we will explain how TRS-IO performs its magic.


TTT105

Title: TBD

Instructor: TBD

Abstract: We are leaving one slot open for a Color Computer focused class. We are working on some options and will update this entry when those plans are finalized.
