FPGA virtual Tandy TRS-80 Color Computer 3 (CoCo 3) The FPGA supports DriveWire. Bits 0 and 1 of location $ff96 alters the data “window” present at the $ffax MMU registers: 00 (default). The time has come to consider ditching the desk full of ancient heavy drives that were once required to let a CoCo load software. This is Coco Quest, a site for my TRS-80 Color Computer 2 and 3 (COCO2 and COCO3) programs. The TANDY Color Computer 3 married the elegance of the Motorola 6809 microprocessor with a simple but powerful memory management system breaking the 64kB barrier. For storage, the Color Computer used a 1500-baud cassette interface like the Model III, although the two formats were incompatible. They are still in the CoCo business, and have the gear you want. Existing memory in the Coco3 can be left in place (feel free to remove if desired), and no capacitors must be clipped or otherwise removed. I'm just picked up a a CoCo3 so I am pretty new to the scene. For the next ten years as a kid, teen, and college student, I worked every job I could to buy computer hardware, software, and books. I wrote dozens of games between 1987 and 1991 which were sold to and distributed by T&D Subscription Software of Holland, Michigan. Search refinements. Compare. Save color computer 3 to get e-mail alerts and updates on your eBay Feed. It wasn't until the CoCo 3 that both composite and RGB output were added - RGB being essential for the new 80-column text and higher resolution graphics. The Color Computer 3 (catalog # 26-3334) debuted on July 30, 1986, 6 years and 1 day after the debut of the original TRS-80 Color Computer. The TRS-80 Color Computer, often referred to as CoCo by its users, started out as a joint venture between Fort Worth based Tandy Corporation and (then) Austin based MotorolaSemiconductor, Inc. to develop a low cost home computer in 1977. Features: 512K SRAM - low power consumption, no external power source needed. Retrocomputing is a hobby of maintaining and using vintage computer hardware and software today. CoCoVGA should be electrically compatible with any system with a 6847 or 6847T1 (usually marked XC80652P).

In addition, the on-board expansion capabilities did not support expansion options greater than 512kB. Your monitor There are several factors that may cause color distortions: Old monitors can be burning out. Tandy executive Ed Juge stated that year that "No home computer on the market today has the potential horsepower of the Color Computer ... we believe [it] also has a good future".
