Rescue of Four Phase Systems mini-computer from Tampa (long)

Just some slight corrosion. The problem is that many of ICs on the boards are custom Four Phase chips. Finding replacements for ones that may turn up bad will be difficult, to say the least. The other problem is that the backplane seemed to have some corrosion, so the slots will need clean-up. I'm expecting that after I inspect it more closely I will find that it is a big mess, but we'll see. The most important thing is that the machine was preserved. We did also find a couple tapes laying about that may or may not have the OS on them, and then may or may not even be readable anymore (I'm guessing towards not). We also found a couple hard drive platters, one in the drive and one sitting out. I left the one sitting out, as I figured it was a total loss.
