It's replacable, but there's no clearance between the bottom off the battery tray and top of the clock module to add a socket. On my SLT/286, since I _have_ no battery, I cut a hole in the aluminum to let the top of the module stick up. One "problem" is that the model of Dallas module that the SLT/286 uses is no longer available because of a Y2K bug. There is a substitute, but I don't know if the SLT/286 BIOS likes it or not. For now, for mine, I found a newer Dallas clock module of the exact same part number, but with a newer battery. I've also hacked the old one to expose the battery leads and soldered on an external battery connector. Mine also sees regular use (when I'm home), as a platform for my ISA-based device programmer (UP600A). -ethan -- Ethan Dicks, A-130-S Current South Pole Weather at 07-Jan-2004 18:19 Z South Pole Station PSC 468 Box 400 Temp -19.6 F (-28.7 C) Windchill -62.1 F (-52.3 C) APO AP 96598 Wind 14.7 kts Grid 344 Barometer 687.6 mb (10341. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html
