TJBChris | TRS-80 Model 16B Real-Time Clock and XENIX 3.4 @TJBChris | Uploaded March 2023 | Updated October 2024, 4 hours ago.
The fine folks at Tandy Emeritus were nice enough to send me a board for their real-time clock add-on to the SRAM expansion card. I Install it into my TRS-80 Model 16B and install XENIX 3.4, which contains native support for the SRAM card and the RTC.

Check out a detailed overview of the SRAM card, MMU, and XENIX 3.4 here: youtube.com/live/7jBKwWGcpl8?feature=share
