Well done! Perhaps glass case it to keep it around? How many hours into the project? I am impressed! Ed# In a message dated 12/27/2016 6:41:32 P.M. US Mountain Standard Time, hilpert at cs.ubc.ca writes: https://imgur.com/a/JNp7m

PDP-6s at MIT

No, their KA10 had a paging box, made by System Concepts - probably programmatically similar to the ones on the other two KA's (looking at the ITS source would probably verify that). Note that in addition to the paging box, there were moderately extensive mods to the KA10 itself (on all three machines) to add a variety of instructions (to do things like, IIRC, flush the paging entry cache). Did the original KA10 have XCT too? And then there were things like the MAR. Now, how soon after their KA10 arrived it had the paging box, etc, added I have no idea - it sounds like they ran it without paging for a while. Noel

Absolutely. But this is likely as close as I'll ever come to having a first generation machine, something unfathomable to me as a kid. Apologies for the radio-silence, we've put 1200+ miles under our belts since Monday morning. Today we cross into Alberta. Will keep you all posted on how it goes. Thanks, Cory=

DEC banner panel

> From: Tony Duell > Does anyonre know what the thickess is? 0.7 mm. (That includes the paint layer.) > I also don't know how they are fixed to the plastic header panel .. > Maybe some kind of double-sided tape? One of mine (ca. 1970) has a sheet of double-sided tape which covers the entire thing. (The glue on it appears to have hardened/failed, and the whole works feel out of the plastic panel.) Noel

DEC banner panel

by ard.p850ug1＠gmail.com

I am starting to fill a spare H960 with my PDP8/e system. Starting as in cleaning up the rack, sorting out the power controller, etc.... This is a somewhat odd question for me as I don't normally care about such things, but I might as well try to get it right... Anyway, I have one of those plastic banner panels for the top front of the rack. It's missing the insert (just the black plastic part), but I would guess (based on what I know of the history of the rack) it would have been the magenta one for PDP11s. Was there a yellow/brown one for PDP8 systems? If so, is a scan available anywhere? Is there any way I can get it printed (and onto what) in the UK? I don't have a large enough printer to do this. Has anyone made said panels before? How did you do it? -tony

PDP-6s at MIT

> From: Lars Brinkhoff <l > (What is it with Swedes and ITS?!?) They're definitely seriously crazy. I myself attribute it to the weather. :-) You probably already know this, but I doubt everyone does, but shortly after MIT-MC (the KL ITS) was shut down, a bunch of (crazy - redundant, I know :-) Swedes showed up at MIT with a shipping container (perhaps under the mistaken impression that Cambridge was Lindisfarne ;-), and loaded the KL into it, along with, IIRC, one of the KA ITS machines - possibly AI? They then shipped the whole thing back to Sweden. ISTR that they actually got the KL to work, but I don't know what the current status of the whole works is. (Me, if I'd taken a KA, I would have taken a second one for spares! The parts in that thing are _seriously_ obscure. :-) Noel

Rack Headers, banners or whatever you call them.

by rodsmallwood52＠btinternet.com

Hi Guys Based on the 8/m rack header scan that came in overnight I have done a quick Inkscape artwork. Its not production quality, sized or color matched but ok for a prototype. Printed on aluminium or decal and roll out the air should be possible. Rod

PDP-6s at MIT

> From: Adrian Graham > I was born 10 years too late to see it all as it grew. ... these early > years are fascinating to me. Well, you _can_ still experience ITS! It runs under a number of PDP-10 simulators (and there used to be an 'open-access' ITS system on the 'net at its.svensson.org, but alas it doesn't seem to be up any more - although in a fit of fore-sightedness, I downloaded the source to the HTTP server he wrote while it was still up). But you can still download one of the emulators that supports the special ITS instructions on the PDP-10, KLH's KLH10, and SIMH; instructions, files, etc here for KLH10: http://klh10.trailing-edge.com/ and SIMH: https://www.cosmic.com/u/mirian/its/ which give step-by-stop on how to get ITS running.
