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.

Please note that the content of this book primarily consistsofarticles available from Wikipedia or other free sourcesonline.High Quality Content by WIKIPEDIA articles! The Radio ShackTRS-80Color Computer was a home computer launched in 1980. Despitethename, the "Color Computer" was a radical departure fromearlierTRS-80 Models - in particular it had a Motorola 6809Eprocessor,rather than the TRS-80's Zilog Z80.The Motorola 6809E wasa veryadvanced processor, but was correspondingly more expensivethanother more popular microprocessors. Competing machines such astheCommodore VIC-20, the Commodore 64, the Atari 400, and theAtari800 were designed around a combination of the much cheaper6502,paired with dedicated sound and graphics chips and were muchmorecommercially successful in the 1980s home computer market.SteveWozniak once commented that the 6502 was 1/4 the price oftheMotorola 6800 when the original Apple was being developed inthelate 70s. By 1986 prices for 8 bit processors haddroppeddramatically from the late 70s, but the MC6809 was stilljust overtwice the price of a MOS6502.
