Quote from: bmwcyclist on Today at 02:47:56 PMCan I add a modern battery solution to my 2/10 to hold time and "date"?
In the late '80s Dafax was selling a made-to-order COPS battery backup for the 2/10, but I never saw one. It used NiCd like the ones that leak in the 2/5.
IIRC, the 10 pin header on the 2/10 I/O Board has the +5 Standby voltage, but no ground, so there isn't a really trivial way to connect it.
As long as the Lisa is connected to AC power, the time should be retained, so if using a power bar to eg. turn off peripherals, perhaps you can power the Lisa separately.
