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.

Any interest in a Floating Point Systems AP-120 array processor?

2021-02-27 Thread Josh Dersch via cctalk
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.

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.

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.
