My Lisa has an I/O board that has a four pack of NiCAD AA batteries, what should I do?
You should immediately remove the batteries! If they haven’t already leaked, you are very, very lucky. Most of these are very old and the batteries have leaked, usually damaging the board with corrosion! There is little value to replacing these batteries with new ones, as good ones will only maintain the time for a few hours while the Lisa is unplugged. This is probably why the I/O board used in the Lisa 2/10 does not have backup batteries. It is perfectly fine to run a Lisa without these batteries, all they do is maintain power to the floppy RAM (which contains the equivalent of the Mac’s PRAM) and the real time clock in the COP421. This will be maintained just fine as long as the Lisa is plugged in to power, even though the Lisa is turned off. That said, the real time clock may be useless as it’s range is from 1980 to 1995 (unless you are using an updated version of MacWorks Plus II), and unless you are using your Lisa regularly, you are better off not leaving your Lisa plugged into
