I've finally managed to partially satisfy my nostalgic obsession to resurrect a PDP-10. I just recently located a KS10, and, after a 480 mile mile trip in the back of my poor little pickup truck, it is now safely sitting in front of my garage (still in the truck... It will be _in_ the garage as soon as I can con a couple of my friends into giving me a hand. This is not a light load :-) The next thing I'm going to need is a Massbus drive (preferably, an RM80) If anyone has one of these that they would be willing to part with, please drop me an email note. I'm located in Virginia, but I'm willing to drive a reasonable distance to pick one of these critters up (the closer the better, of course :-) Shipping would be impractical. The other possibility is to build an adapter that I could stick in a PC which would emulate a Massbus device, but to do this, I'd need pretty complete specs on the Massbus (i.e. pinouts, timing, etc.) Does anyone happen to have this info? I've done a dejanews search, but nothing really useful turned up. If I can locate a partially complete RM80 (i.e. one with the Massbus to modified-SMD adapter still present and intact in the drive pedistal, then I might try to build an adapter to emulate the modified-SMD interface supported by the massbus adapter cardset. I suspect this might be a simpler emulation, but it would still require info on the modified-SMD interface supported by the RM80. If anyone has details on this interface, please let me know! BTW, I'm also on the lookout for TOPS-10 and/or TOPS-20 load tapes (or images thereof, or bits and pieces... whatever I can find that will get me closer to bringing this critter back to life! -Thanks in advance... -al -acorda(a)geocities.com
