Elf 2000 Main Board
- DS1210 VBAT2 grounding issue
- On the Elk2K main board, chip U5, the DS1210, MUST have pin 7, VBAT2, tied to ground (Pin 4).

STG1861 Board
Disk/UART/RTC/NVR Board
- There is a minor errata on the Disk/UART/RTC/NVR Board. On U7, the 16C450 UART, pin 36 /CTS is an input which is not connected to anything. As far as I can tell from the datasheet this IC does not have pullups fitted so this pin should be connected to something. On my board I have run a wire from /RTS pin 32 to /CTS pin 36.
