The HP41C -- it lives!!

[ColinJDenman]

After 7 years in storage (no batteries), and despite a little reseating of modules and rubbing of battery contacts, my HP41 powered up today. Oddly, I didn't need to dig out the manual to remember functions, setting up the date/time or entering a quick program. It was a joy of ergonomic thoughtfulness after suffering several months trying to get used to a Prime.

Now. Any advice on improving contacts on the modules and battery terminals -- the latter show some corrosion on 1 and 3 (looking in as 1234 left to right), although I remember having an occasional MEMLOST before it went for a rest.
