MiSTer RTC Real Time Clock Board v1.4

Some cores such as the ao486 (PC), Archie (Acorn Archimedes), BBC Micro Master 128K, Color Computer 3 (CoCo3), Commodore 64 (C64), Game Boy, Game Boy Color, Game Boy Advance, Minimig (Amiga), NeoGeo, MSX, SNES (Super Nintendo), TSConf (ZX Spectrum), QL (Sinclair QL), Zet98 (PC-98), ZXNext (ZX Spectrum Next), PC8801, X68000 use a clock, so MiSTer is able to provide the real time for such cores with the addition of this addon board.

This addon board provides real time offline, another benefit is any data written to the MiSTer’s Micro SD card will have the correct timestamp. The RTC board for the MiSTer FPGA is plugged into the Terasic DE10-Nano’s LTC connector.

The MiSTer Real Time Clock’s I produce use a genuine Amphenol ICC header connector which enables proper installation of the RTC onto your DE10-Nano. In contrast, many other Real Time Clocks utilise incompatible connectors that require you to cut and damage the plastic pin header surround on the DE10-Nano board. Doing so would void the DE10-Nano warranty with Terasic.

You can be reassured knowing each Real Time Clock (RTC) v1.4 board has been tested before despatch on a live MiSTer setup.
