By "bolt head tapers", do you mean the special bolts with countersunk heads, or the countersunk holes in the extension feet? Whichever it was, I can provide photos and/or measurements, as needed.

I love to buy some if anyone ever makes reproductions.

I made two pairs of repo ones that turned out beautifully. They have a welded steel bar load-bearing skeleton and adjustable pad like the original, and a 3D-printed shell sprayed in satin black that completes the aesthetics and follows the "six foot rule" in that they probably wouldn't be picked out from the originals from a few feet away. I have yet to machine the bolt head tapers to the originals but lost the photo of one that was posted here some time ago. I got a lot of help from cctalk on the dimensions of the foot a while back, but some of these are still a tiny bit inaccurate, but I can't expect the average person to have a surface table, height gauge, angle gauge etc. I was planning to make a few pairs for sale some day. If there was sufficient interest I can get to fabricating the cutting, bending and welding jigs to produce then more quickly than the completely hand-made ones I have done. The biggest problem is I'm not sure how much they would cost. Also I have not yet laser-cut the accompanying kick panel. I have the dimensions for that but I would rather measure one myself before committing to those. http://www.surfacezero.com/g503/data/500/Stabiliser_feet_02.png http://www.surfacezero.com/g503/data/500/Stabiliser_feet_01.png Steve.

Any interest in a Floating Point Systems AP-120 array processor?
I picked this up a number of years ago for reasons that entirely escape me. It's certainly neat, but I don't see myself ever actually using it and it's large and heavy. Documented here: http://bitsavers.trailing-edge.com/pdf/fps/7259-02_AP-120B_procHbk.pdf Mine appears to have a DEC-style interface but I'm unsure what it talks to on the DEC side of things. I can take pictures if there's interest, but it's fairly nondescript, just a large white box with rack-mount ears and a small panel with some switches on it. It's in the Seattle area if anyone wants it, and it's free! Shipping is... not something I really want to think about right now. - Josh

I think they've come up before as something that would be worthwhile to cast a couple dozen of. I don't have any that aren't firmly attached to a full rack, and I have racks with none. -ethan

I realize these are uncommon; curious if anyone has a spare pair somewhere (hey, that rhymes.) I'd like to be able to pull out the CPU on my 11/70 without worrying about the whole thing tipping over and crushing people I care about. It's the little things, really... Thanks! - Josh
DOS/Batch 10 source disks
Did someone on the list buy the pair of source RK05's on eBay? https://www.ebay.com/itm/PDP-11-Program-Monitor-V10-02-CUSP-and-Device-Driver-2xRK05-DEC-Digital-PDP/353391043210 I bought the fortran source disk that was listed at the same time, but didn't go after these because of the cost and I may already have it in the archived DECtapes on bitsavers.
