| 2026-03-12: Cocopedia.com is now using a new caching system that should make things faster. Please let me know if you encounter any new issues.
2026-03-15: MediaWiki has been reinstalled and the old database and files restored. It was pretty clogged up from being upgraded so many times since 2004. I am also testing out Cloudflare to see if it can prevent the 'bot assaults that took the site down last year. 2026-03-16: Special thanks to Don Barber for hosting a backup mirror of CoCopedia: https://cocopedia.dgb3.net |

The heart of the Deluxe RS-232 Pak is the Synertek 6551 ACIA. It has an on-chip baud rate generator, programmable interrupts and status register for ease of operation, false start bit detection, and echo mode
This ACIA board is memory mapped to addresses $FF68 (65384) to $FF6B (65387).
The 6551 uses 4 memory addresses for the following functions:
| Address | Write | Read |
|---|---|---|
| FF68 | Transmit data Register | Received data Register |
| FF69 | Soft Reset | Status Register |
| FF6A | Command Register | |
| FF6B | Control Register |
