My to-do list has me doing the rounds of all my machines to check them all for the batteries. I'd like to replace rather than remove though, but that could get expensive at about ?10-12 pounds per machine for the cordless phone battery packs sold by Maplin. Maybe there is a better alternative, I should go and take a look. Regards Rob

I was just looking at a system with an M7626 KA660 a couple of days ago and the network connectivity through the H3602 AUI Ethernet port was very flaky. The H3602 had some signs of leaking battery corrosion that I had previously tried to clean. I swapped that H3602 panel with another one that also had some signs of leaking battery corrosion and that one seemed to work OK, at least for now. Trying to correct whatever is damaged on the bad H3602 panel will be a pain. It's not worth the risk of leaving those NiCad battery packs in any old DEC gear. It's not that much of a pain to set the date and time every time I actually get around to powering on the systems. The early VAX 3100 desktops have those same evil NiCad battery packs.

I know that they had new batteries. Not new in the DEC packaging but newly mad they may be able to do some thing for you. Contact Wayne Beeson and let him know I sent you. url is nemonix.com <http://nemonix.com/> phone is 508-393-7700 Coming from a DEC background it was amazing to see this hardware still in active work. On of my favorites was discussions was around fans. When the hardware was originally made they did not include sealed fans for general sale so as the fan got old and slowed down it would gradually heat up the mother board so folks thought it was a mother board issue, get it replaced and then a few moths later the fan would break and people would have t replace. Nemonix did both so it was not an issue just uncomfortable for the customer. If there is anything I can do to help please just let me know. Warm Regards, Sue wrote: for the batteries.
