I really believe a person would make an entire interesting collection of just logic trainers! we have a couple of the MINIVAC trainers too one I keep under glass and the other I take out for show and tell. We have a fabritek and a few other later ones too. In a message dated 9/23/2015 9:58:30 A.M. US Mountain Standard Time, cube1 at charter.net writes: On 9/23/2015 11:28 AM, couryhouse wrote: > Wow!

One with PDP-8/PDP-12 style switches shows up in the back of the 1969 logic handbook. There is one that looks somewhat like mine on the inside front cover of the 1970 logic handbook, and the panels that would be possible to include in one start at page 353. So that dates it to 1970 or after.

LA120 ROM & new member intro

by thebri＠gmail.com

Hi. The original ROM request showed up just before I started receiving messages this morning, and I only got the tail end of the chatter. Instead of tacking a reply on to that, I thought I'd just start a new thread and introduce myself at the same time. Here's what I think is 23-038e4-00 from an LA120 (with a bad print head, and dead pin drivers as well). I couldn't find anything to compare it against, and the adapter is new. So it might be gibberish. I did see, at least, [A-Z] in the dump, so maybe it's good. As for the introduction, I started life on the Apple II in fourth grade or thereabouts, finally got a Commodore 128, then an Amiga, then jumped over to UNIX (BSD mostly) and stuck there for years doing software. After funding stopped being an issue, I decided to get back to more interesting and/or simple hardware, and electronics in general. I seem to have collected a rather complete HP86/87, under the illusion of using it for an GPIB controller. I'm now wrestling with an apparently dead PSU on a MicroPDP (actually, I just now gave up on it), and am slowly fixing up a PDP-8/a. It has two CPU boards, one of which ignores the HALT instruction. From the schematics, I think it's one faulty 74ls chip, but I haven't tried fixing it -- the machine has been down for cleaning/painting for many months. I just got it put back together this weekend. I also swapped out the fans for modern (quiet) 12v fans (driven off an isolated power supply powered by the original 120 vac fan supply)...and now hear the transformer buzzing away. Win some, lose some. Sigh. Congrats on making it to the end! Cheers! b

cctalk Digest, Vol 15, Issue 23

So, I wrote my primitive little 8080 assembler, in Fortran-77. I started using it the next day, and my manager asked where I got it. After I told him, he said that I should have asked him first, because he could have put together one using editor macros pretty easily - in less than a week, he estimated. The fact that I knew nothing about macros notwithstanding, I noticed I thereafter got a lot more autonomy when I told him I wrote mine in a single (longish) day... ~~ Mark Moulding

Structured Fortran

by cruff＠ruffspot.net

At NCAR there was a structured Fortran preprocessor named IFTRAN that was in use for a long time. The earlier versions of the NCAR Local Network (NLNET), later renamed MASnet (Mainframe and Server network), as well as a variety of graphics packages were written in it. I still have the IFTRAN to C translator I wrote to convert everything to C code so we didn?t have to spend money on Fortran compilers on the Unix boxes. MASnet was a Hyperchannel cross bar network used for batch job submissions and data transfers to/from the Mass Storage Server (MSS), the supercomputers and the front end servers. Eventually it was migrated to run on top of TCP/IP and Ethernet when the Hyperchannel hardware got expensive to maintain and comparatively slow.

Yes host was having hickups it seems. Take a look at the neat logic trainer by IBM at link below, Wish I had more info on this IBM tube type digital logic trainer kit. comes in a wonderful fitted case with all kinds of plugable units see url http://www.smecc.org/wpe_files/wpe45.jpg The logic trainer is on the left at the right is SAGE plugable unit This was a really early photo as I think I had just finished building the display case and that was all that was in it! that entire 8 foot case is pretty much SAGE display. SAGE is near and dear to some of us as we had a DC across from Luke AFB about 15 minutes away from our building. We even have some remains of come gear from the first prototype Q7 system that I need to hunt down more info on. Ed# _www.smecc.org_ (http://www.smecc.org) In a message dated 9/22/2015 7:01:09 P.M.

You are indeed lucky they ceased. Mine did not start until my 20s It is definitely one thing that made sure I had my own business. Many people in a supervisory position have no understanding of what it is like. Ed# In a message dated 9/22/2015 10:10:22 P.M.

Had some of those while I was in High School, complete with squiggly lines, often nausea and hours of intense pain. You have my sympathy. Then one day I started to get one while I was driving from home to the local music store. I pulled over, took a deep breath and (I kid you not) told myself no, you are not going to get a migraine, ain't gonna happen. It went away almost immediately, and I haven't had one since. Go figure. Almost certainly pure coincidence. [I wish that would work for everyone. Sigh.] JRJ

Ed reply - Jay - I did all that yeas ago... It did not smoke but it also did not do much else. LOOPBACK to... I need to find manuals and a system tapes probably. Sure looks pretty though ( and better with a blue et head terminal on top!) I wish I had learned more about DG stuff. I had some folks that had helped me when I was starting out in the business and when DG stuff showed up or a local needed something usually I turned them over to one of my friends. eventually I was even handing of DEC deals to friendly people and just settled in on the HP stuff. It worked well that way but I sure did not learn much abut DG stuff! Ed# _www.smecc.org_ (http://www.smecc.org) In a message dated 9/22/2015 3:25:29 P.M.

Taking it apart, cleaning it up, replacing anything obviously bad, checking out the power supply.... all things you can likely do without a manual. You could go a little further than that just by asking a few questions here; folks are glad to help! Think of all the great stuff you'd learn along the way!! You'd find manuals and tapes at some point I'm sure!

Jay looking at - your flicker page I would say you have a mountain of it! <grin!> I see you have one of those small reel tape drives also like we do in our s20... what is the interface on them? what BPI ? who actually made them? https://www.flickr.com/photos/131070638 at N02 In a message dated 9/22/2015 3:25:29 P.M.

Not to mention, there's the "classiccmp law of attraction". Basically if you get just part of a machine, the rest will suddenly start appearing :)
