Ah! Ok! heard of it but never seen an installation. Great find! I am a little foggy on it but I somehow remember it being able to control external devices for process use vs. the usual IBM stuff that was just 'data processing' Ed# In a message dated 11/22/2016 12:31:26 A.M.

I always knew them by their code names ? different varieties of peaches?so named because they were developed by IBM?s GSD division which was headquartered in Atlanta, GA (even though all of the development was done in Boca Raton, FL).

ISO: PDP-11/40 LTC and Stack Limit options

I spent a short time looking at the KT11-D and KJ11-A prints, trying to see exactly what the KT11-D wanted, but I wasn't able (yet) to fully grok the interaction. >From the KJ11-A prints, you can probably work around not having a KJ11-A card by strapping the relevant outputs high or low (as the case might be), i.e. simulating a KJ11-A which is not reporting a problem. Like I said, V6 doesn't use the SLR for anything, so it's it's not actually working (i.e. reporting stack transgressions), no biggie. If you're determined, I did scan in a KJ11's PCB, so it would probably be possible to produce 'after-marked' ones - it's not a very complicated card. >> You will also need the KE11-E (M7238), as the Unix C compiler emits >> MUL, DIV etc, and even the bootstrap uses them.

I suppose I could run Ultrix-11 instead (I have that on my > 11/34 at the moment) as it'll run sans floating point hardware, We seem to be having a communication failure. You don't need floating point to run V6 or V7 on an 11/40. In addition, the hardware floating point hardware on the 11/40 (the FIS) is a variety that Unix doesn't support anyway (in the sense of, the C compiler doesn't generate FIS instructions). It's the Exteded Instruction Set (EIS) card (which supports MUL, DIV, ASHC, etc) which is necessary. No way UNIX (of any flavour) will run without those instuctions (and thus, that card). If you don't have an M7238, start looking.... BTW, what is your mass storage device? RL's? If so, vanilla V6 doesn't support RL's, but I do have a V6 RL driver, I can either build you a system that will run on an RL, or (if you bring up V6 under an emulator, so you can build systems, etc) provide it so you can add it. You'll also need an RL bootstrap (again, those are available, but not in vanilla V6). Also, how are you getting the bits onto the mass storage? V6 can only be 'cold installed' onto a blank machine from a TM11 or TM02 tape drive. Failing that, you have to put a V6 filesystem onto a disk on some other machine. Do you have the ability to write packs on another machine/OS, and the ability to get a Unix file system onto that system? Failing that, I'm in the process of getting VTServer working to transfer V6 over a serial line to a blank machine (my situation) - I got distracted before I got 100% finished, but I have it all scoped out, and can get it done in a couple of hours from where I am now.

Interested in UNIVAC 9000 Series (and IBM 360)

by billdegnan＠gmail.com

http://vintagecomputer.net/browse_thread.cfm?id=658 Hot business women posing with classic UNIVAC hardware and a link to a very rare 1968 business proposal by UNIVAC to Philip Morris, an attempt to sell either a 418-III or 9400, pricing, comparison with IBM 360 models. Included with the proposal were a handful of product brochures. I scanned some of my favorite photos. Bill

ISO: PDP-11/40 LTC and Stack Limit options

A KM11 might help, if you have one: there are a couple of sources for new ones (I got mine from Guy), it will allow you to single-step the microcode, etc, etc. > My ultimate goal is to run V6 or V7 UNIX on it -- I have the MMU but > I'm looking for an M787 (line-time clock) and M7237 (stack limit > register) to complete the set. You don't need the SLR to run Unix V6 (in fact, IIRC, it doesn't use it). For the clock, you don't absolutely have to have a KW11-L, you can substitute a KW11-P - but V6 _has_ to have one or the other, or it panic()'s - some things in the kernel have to have a working clock. You will also need the KE11-E (M7238), as the Unix C compiler emits MUL, DIV etc, and even the bootstrap uses them. The KE11-F (M7239) is useless; the V6 Unix C compiler doesn't generate that type of PDP-11 floating point. Noel

ISO: PDP-11/40 LTC and Stack Limit options

by derschjo＠gmail.com

Hi all -- I'm finally turning my attention back to my 11/40 (which I started working on 7 years ago and never quite got around to finishing -- I've learned a lot since then and I'm hoping to be able to debug it properly now). My ultimate goal is to run V6 or V7 UNIX on it -- I have the MMU but I'm looking for an M787 (line-time clock) and M7237 (stack limit register) to complete the set. I have other DEC stuff for trade, drop me a line... Thanks! Josh

Slide Rails for Integrity and/or BA23

by pontus＠Update.UU.SE

Hi I've just brought home a 42U rack and started mounting things currently in shelves and on the floor. But I'm missing some hard to get slide rails. Does anyone have a spare set of rails for an Integrity rx2620 or QBUS BA23 box for sale? The Integrity rails look like this: http://www.trademoon.com/assets/images/default/A6939AZ.JPG BA23 shelves look like this (except some missing parts): http://www.plccenter.co.uk/en-GB/Buy/DEC/702076101 Kind Regards, Pontus.

Some scrapper in NC has an old machine Labled TRIAD he is scrapping

by jnc＠mercury.lcs.mit.edu

> From: Josh Dersch > Someone should try to rescue that; they're very rare... I personally don't want to get into this (I'm already knee-deep in PDP-11 stuff), but I can help with the logistics; I'm down in SE Virginia, very close to the NC line. So if someone wants to do this, but is e.g. on the West Coast, I can wrangle getting it, and getting it shipped out. Noel
