I would be interested in the XT motherboards. Mike Rosen Sent from: My extremely complicated, hand held electronic device.

Just wanted to share the pictures. I also have a 386 or 486 motherboard with cards and drives, last ran Linux. I need the case (baby XT tower, need that for the other PT68K). I still have more just to look through. I wonder what a IBM PC motherboard is worth? Not sure I want to sell that. I also found an XT SCSI card. Not for sale but if needed to be borrowed. I have one. -- Linux Home Automation Neil Cherry ncherry@linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies

Search on the model to see if it has know problems specific to it. If you are wanting to preserve the contents have a plan to back it up if it does work since it may not for long. Especially for loose drives check for physical damage. I haven't had cap problems but have seen other have. If nothing obvious wrong I normally power it up and see whats up.
