2025-12-29: I have restored the wiki to a backup from the end of November. Starting in September 2025, accesses went form the 800MB-1.2GB range per month to 26GB in September, 42GB in October, and 70GB in November with most accesses originating from China. As soon as I realized what was causing all the access problems in November, I shut it down (it had reached 36GB by then) behind a password/login screen. The database had gotten corrupted, and I tried a restore from just before the spike in access but that didn't work. Thus, end of November. I still have the other daily backups so if there were any important additions in December, let me know and maybe they can be recovered. - Allen H.

The Radio Shack TRS-80 CGP-220 (Cat. No. 26-1268) is a color inkjet printer. "CGP" stands for "Color Graphics Printer" and the 220 was the second and final printer in Radio Shack's CGP series (the first was the CGP-115, which was actually a plotter rather than a printer). The 220 debuted in 1984's RSC-10, p.31 with a list price of $699. Like many Tandy products sold through Radio Shack, it was a licensed (and customized) version of another company's design, namely the Canon PJ-1080A, which Canon licensed out to many other manufacturers as well, including IBM [1].
Every CGP-220 came bundled with a cassette containing a CoCo color screen dump program in machine language. This despite the CGP-220 also being compatible with, and marketed to, non-CoCo and even non-Tandy/Radio Shack computer owners. This shows how committed to the CoCo Tandy was at the time, and helped to raise the CoCo's profile outside the CoCo community.
The CGP-220 actually had the same Motorola 6809E CPU that the CoCo had, as well as the same 4K RAM the original CoCo came with.
