We’ve already told you that everyone who owns a TS2068 should buy this book [SYNTAX May’84]. Even if you never need this book, it will increase the resale value of your 2068 because it describes the entire system in intimate technical detail.
If you don’t program in machine code or understand digital electronics, this book probably won’t be to useful to you. It assumes a great deal of prior knowledge about computers and electronics.
But if you need to know about how the CPU, ROM, RAM, sound chip, joysticks, keyboard, display hardware, cassette ports, or any other facet of the hardware works, or you need pinouts for any of the connectors inside or outside, or you need to understand how the ROM cartridge software gets loaded, or how the operating system calls work, or how the machine interfaces to available Timex hardware, you will want a copy of this book. It also contains sections on known bugs in the TS2068 ROM (some of them rather obscure) and listings of machine code packages for doing 80, 64, and 40 column displays, and movable graphic blocks (sprites). It even includes a PCB layout (including solder mask) for an EPROM board for the dock connector.
If you’re serious about your 2068, or just to increase resale value, this book is well worth the price. It tells it all.
