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.

Hardware design and integrated circuits
Internally the CoCo 1 and CoCo 2 models are functionally identical. The core of the system is virtually identical to the reference design included in the Motorola MC6883 data sheet and consists of five LSI chips:
- MC6809E Microprocessor Unit (MPU)
- MC6883/SN74LS783/SN74LS785 Synchronous Address Multiplexor (SAM)
- MC6847 Video Display Generator (VDG)
- Two Peripheral Interface Adapters (PIA), either MC6821 or MC6822 chips
