Help with value of IBM RT-6150

A recent storm blew a tree over and into my garage. It so happens that I had an computer near the spot where the tree went through the garage. Although not physically damaged by the tree, there was a lot of water damage to the computer and especially the monitor. Being an older machine, I am not sure how to place a value on it for insurance purposes. If anyone out there has seen anything recent on the machine as to what they are selling for, I would appreciate sharing of that info. The computer is an IBM RT Model 135, Type 6150. It has a 5 1/4 floppy, and two hard drives (100MB & 300MB), plus the usual video and network card. The monitor is an IBM Model/Type 5081-19, 19" color with RGB inputs. I am not trying to come up with some inflated value for this thing to take advantage of the insurance company, just a reasonable fair value to settle the claim. The machine worked fine before I parked it in the garage. I know that there is probably cases where the machines have just been thrown or given away, but would like to get some compensation for it, if nothing else for what was a working 19" color monitor. Thanks in advance for any helpful info. Mike Thompson mzthompson(a)aol.com
