I've been working on another 9100FT, and like a lot of them, the RTC battery was depleted. I searched around a bit and found a guide to hacking in a button battery holder. Figured I had nothing to lose since it was dead already, so I gave it a try. It's not going to win any awards, but it does work. Seems like a decent alternative if you can't find NOS, don't want to spend what they cost, or want a permanent long-term solution. https://www.classic-computers.org.nz/blog/2009-10-10-renovating-a-dallas-bat... _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
