11/45 pictures & questions

I couldn't wait, had to get the 11/45 off the trailer and dig around in it. Upon first close inspection, the thing is FILTHY. It will take some very major cleaning before attempting to do anything with it. However, from a first looksee - it definitely doesn't look "beyond all recall", it looks like it will clean up nicely. While very dirty, I can't see any rust anywhere. Good sign. Some pictures are at http://www.ezwind.net/jwest/1145 Questions... There is a separate power supply at the back top of the rack, which powers a DEC brand backplane mounted "pins forward" in the front. There's also some lights & switches here. There's some flipchips in it, and lots of what look to be D/A cards. Does anyone have any clue what this was used for? I took extra pictures of this part - tried different focus settings & all so hopefully some will be clear. Looks like the machine has no FP option, and 8K of core memory. I haven't decided what OS I want to run on this thing yet, maybe RT11, or RSTS, but I was really hoping to run 2.9BSD or Unix 7 or some flavor of unix. That's not gonna happen with 8K of core. I have some RL02's I could put on it. Anyone want to trade the bits to make it use semiconductor memory in exchange for the core backplane and core boards? Is FP required for anything I've mentioned? I'll get it up and running on 8K to test & refurb, but definitely want to go the semiconductor memory route so I can run one of the above O/S's. Hey, can this thing use any of the memory boards I have in my 11/44? Thanks for any advice! Jay West
