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.

Home / Hardware - CCR-81 (26-1208)
.jpg)
The TRS-80 CCR-81 was a cassette player and recorder from Radio Shack. The "CCR" in the name stood for Computer Cassette Recorder. While a fully functioning audiocassette player and recorder, the CCR-81 was also a computer data input/output device.
Radio Shack produced few software titles on tape, preferring its proprietary Program Pak cartridge-based system, but a wide variety of third-party developers released software on tape as a standard format. Usually the price for a program was the same whether on tape or disk, but the cost of the drive hardware was much higher for a disk drive.
Like many tape recorders of the day, the CCR-81 was a full-sized desktop model, with a large speaker, intended to permit multiple users around a table, such as participants in a business meeting, to hear the sound. It was followed up by the much smaller CCR-82.
