I have been intrigued by the 4xx cameras for a while, but have never seriously looked at buying one.
I'm in good shape I think to handle some of the quirks of them. Old computers aren't a problem for me. Not too long ago I bought a bunch of 2gb Delkin industrial cards, and from reading other places the industrial cards in PCMCIA adapters seem to make reliable storage.
The cameras themselves seem plentiful on Ebay, but I've yet to see a charger.
First of all, do I have the correct picture of them that the batteries are "permanent" and charged in the camera? I'm guessing that's what the mini-DIN plug is for but again haven't seen the full set up. Can the cells be easily replaced?(and are they a standard/easy to find size?)
Can a charger be improvised? I'm guessing the battery chemistry is Ni-Cd or NiMH and if so I'm wondering if the correct plug and a bench PSU would do...
