Hi Jordi, I've not messed around with TOPS-10/20 and only VMS on simh, but there you need specify which O/S is running inside the VM and specify it with something like: set cpu idle=VMS If I get it wrong or omit it, then it will sit there wasting a huge amount of cycles on my alpha. Off the top of my head, I suspect simh is actually looking for instruction patterns for the idle loop and detecting based upon that, which would differ from O/S to O/S. Perhaps TOPS-10/20 requires something similar?

PDT-11

by wilson＠dbit.com

I know PDT-11s are off-topic but they came up before: V6.1 of the Ersatz-11 PDP-11 emulator is now done, and the demo/hobby version is available here: http://www.dbit.com/demo.html This release adds emulation of the PDT-11/130 and PDT-11/150 microcomputers, as well as a rough cut of the Terak 8510/a microcomputer (but the Terak graphics require DOS, Windows, or OS/2 -- no Linux unless/until a better linker turns up). There's an appendix showing how to configure each. John Wilson D Bit

KLH10 on Raspberri Pi / Nodelist update

by jg＠jordi.guillaumes.name

I have put the basic setup in BITXOV:: (default FAL directory), in the file TOPS20PI.ZIP The ZIP contains the compiled binaries and the setup files I use. If you drop the PANDA distribution RH.RP07.0 in the same directory you should be fine. Just follow the instructions in the PANDA docs to set up TOPS-20 networking and you will have IP connectivity. If you want DECNET you will have to uncomment a line in SYSTEM:7-1-CONFIG.CMD (near the end), add the DECNET address to the "NODE" line (it should read NODE NODNAM XX.XX). Add (or uncomment) these lines to SYSTEM:SYSTEM.CMD: NCP SET CIRCUIT NI-0-0 SERVICE ENABLED NCP SET CIRCUIT NI-0-0 STATE ON With all of this you should have both IP and DECNET running...

3B1s and "old school" UNIX, was Re: [HECnet] US Seller with some interesting stuff

by phiber＠phiber.com

I used to use 3B1 and 7300 systems quite a bit. There was a CUI/GUI system called MGR, and they served quite well as UUCP mail-enabled workstations. Motorola 68k based. However, everything from the 3B2 on up was based on the Western Electric 32000-series processors. The Regional Bell's original Operations and Support Systems were largely PDP-11/45 and PDP-11/70 minis. These were transitioned for the most part to AT&T 3B20S ("Simplex" processor) servers towards the late 80's, the internal OSS applications these machines ran being designed by Bellcore. The RT version you're referring to is the AT&T 3B20D ("Duplex processor), which served as the processing core of the AT&T 5ESS (Electronic Switching System), at one time one of the two most powerful digital switching systems in the telephony world. The original real-time Unix developed for this platform (by AT&T) was called DMERT, for Duplex Multi Environment Real Time. This ultimately evolved into the 5E-2000 switch, with the OS evolving into AT&T UNIX RTR (Real Time Reliable). Not DECnet capable. The standard hard-wired networking method was AT&T Datakit VCS (Virtual Circuit System). Telenet X.25 hardware was also a common networking interface. By the way, I'm also from Queens. -Mark On Wed, Nov 28, 2012 at 7:19 AM, Gregg Levine <gregg.drwho8 at gmail.com> wrote: On Wed, Nov 28, 2012 at 9:20 AM, Dave McGuire <mcguire at neurotica.com> wrote: On 11/27/2012 10:25 PM, Boyanich, Alastair wrote: Wasn't there some bitsliced cpu variants ?

I know there was the AT&T UNIX PC which was a 68010 + custom external MMU, but there was also a proprietry cpu version I ran into the trap of in a past life. The "UNIX PC" is the 7300, which is nearly identical to the 3B1. The 3B1 has a slightly larger top cover to accommodate a full-height hard drive, while the 7300 will only hold a half-height drive. They are otherwise identical, using 68010s. I'd sure like to know more about the "proprietary cpu" version you're talking about. -Dave -- Dave McGuire, AK4HZ New Kensington, PA Hello! He's thinking of the WE designed processors that were used in the later units. They were not bit slice but were fabricated using the normal methods. Not surprisingly enough the devices could not even be sold separately. They were ran an appropriately written release of UNIX as native. One of the first applications for them and the later models was in running the first and second generation Electronic Switching Services otherwise known as exchanges. There's a whole article online someplace on the RT extensions that needed to be written out and added to UNIX for that application. ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."

Raspberry PI SIMH-VAX distro?

Anyone running KLH10 in the Raspberry Pi?

by tim＠sneddon.id.au

Hi Jordi, Have you tried running the DEC-10 diagnostics? I'm not a -10 guy's as such, so I might be wrong here, but I think they are called the KLAD pack. Search for KLAD on http://pdp-10.trailing-edge.com/. It should be much easier to pin point which part of the microcode is causing the problems. Regards, Tim.

Does KLH10 assume little endian? Pi is little endian. And, to add some weirdness to this, I have just completed a TOPS-20 boot using the very same binaries... What I have found so far: - The ARM compile of KLH10 does not handle correctly the load of images in DEC-PEXE format. If the simulator is compiled without optimizations (i.e., -O0 in Makefile) then it does not spit any error message when it tries to load KLBOOT.EXE but it doesn't work either. For some reason it does not set up the initial address (but probably the problem is beyond that). I have been able to dump from a KLH10 running in a amd64 linux to a *.sav file and it seems to work... but then it does not recognize the TOPS-10 structures. I will work on both the LOAD problem and the disk problem a little bit. - TOPS-20 (PANDA) does boot, but the networking code does some weird things. Basically, lots of "***BUGCHK IPIBLP*** IPNI input buffer list problem" messages whenever I try to do something with IP networking. I have googled for that bugcheck, and it is related to the system being able to get IP buffers when it needs them. It could be a race condition, or some weird thing related to default word sizes. I'll keep trying... :) Jordi Guillaumes i Pons jg at jordi.guillaumes.name HECnet: BITXOV::JGUILLAUMES
