The RICM Learning Lab was nice and cool today so we spent the afternoon chasing the "LGP GP=GPC PRESET" in the TC12 LINCtape controller. With a logic analyzer connected to lots of the TC12 signals were were able to chase down the signal that is causing the fault. We are now not sure if the signal behavior we observed is the correct behavior, and there is a fault elsewhere. More debugging time and more studying of the documentation is required. -- Michael Thompson

Wang Model 370

by earl＠baugh.org

Howdy, Went on a rescue last night and while there were three machines I knew of (a PDP-11 that I'll give more details on later, haven't looked at boards, etc, since it was part of a Particle Measuring System, an HP 85-ish machine and a slightly later HP machine) there was one thing that I hadn't known about... (aside from the very cool old GE 'scope that the guy is keeping... ) A Wang Model 370 Calculating System with a Model 372 Data Storage System. Gotta say this is the oldest thing I've picked up (1967 it came out). No idea if it powers up or not... Definitely needs a cleaning (basement, fairly dusty unit) but before I did anything, was wondering if there are any experts out there that have worked on one of these before who'd be willing to share any helpful hints on verifying this is working... Thanks... EarltheSquirrel

Time to dig out some of my DEC XX2247 keys

> From: tony duell > The problem comes if the blank is 'restricted'. ... > I would be surprised if the blank for the 11/05/GT40 key was restricted. It's not; IYWR I recently had a bunch of 11/05 keys made for people here, and it just used a standard blank. (In fact, there were several different ones that worked; it's a very short key, and there are different length blanks.) Noel

Time to dig out some of my DEC XX2247 keys

think I have a drawer of them somewhere... HP keys as well. Wonder how many 'buyers ' are out there!? ed# In a message dated 7/15/2015 10:50:33 P.M.

The ACE way or the highway. Oh, I'll bet that there's someone in the far East who'd be more than happy to make you a bucketful. Or you can visit the World-Wide-Black-Market: http://www.bumpmylock.com/chicago-ace-tubular-lock-key-blank-137.html And even better, I suspect a locksmith may, for a fee, get you one of these: http://www.hpcworld.com/Print/pocket_cut-up/manual.pdf Or maybe there's a Chinese clone maker who'll sell you one. In these days of electronic key-cards and whatnot, an ordinary key can hardly be considered high tech security. --Chuck

Reproducing old machines with newer technology (Re: PDP-12 at the RICM)

This confused me a bit, until I realized that you were using "latch" for what I think of as 'SR flip-flop', and "flip-flop" for 'D and JK flip-flops'. Guess that shows how long ago I did hardware... :-) To be a bit more detailed, on the 360's, were those latches 'simple' SR flops (i.e. un-gated), or were they gated? Noel

Off topic- shipping companies

ok and added item there is min size for the min price too... so if you can fit it in the footprint same charge probably as they were sending the palletized stuff as padded. I have had ties I needed some padded and there was still a min. amount of poundage open so I put palletized stuff on with the wrapped but that was because it would have cost the same for the padded without the palletized. rule if you send anything padded van all will be billed as padded van even if was a palate load of paint cans full of dog crap etc etc....
