DMC11 in next simh version... looks nice, and question about TOPS-10

That is what happens here too... My guess is it is necessary to build a modified TOPS10.REL. But without the docs it can be quite difficult. No, TOPS10.REL is just a library (MAKLIB made) of relocatable binary objects (.REL) ready to be assembled. It contains every possible Monitor module for standard configurations. During Monitor linking only the relevant modules are extracted and used to build the final Monitor executable file. When I'll have some spare time, I can try to build a DMR11-enabled Monitor, just to verify that everything works: I've been able to build a lot of Ethernet Monitors with no problems, so this would be to exclude bugs in other modules not used for Ethernet. I've discovered that it wouldn't be so strange to find some glitch that prevents some configurations from building... BTW, I once had to replace a module into TOPS20.REL, i.e. CLOCK1.REL, to take advantage of the KLH10 emulator idle function. I just COMPILed CLOCK1.MAC (and a couple of other required files, notably F.MAC and S.MAC) and then I replaced in TOPS10.REL the old CLOCK1.REL with my new one using MAKLIB. :) The alternative was to patch every new monitor to change a single instruction instead of changing it into the relevant source module. I think it would have been feasible even to directly patch TOPS10.REL, but I found easier to replace the module than to understand and learn how to locate something inside it. Bye, :) G.

DMC11 in next simh version... looks nice, and question about TOPS-10

by gerry77＠mail.com

On Wed, 02 Jan 2013 22:33:33 +0100, you wrote: Now the question. It seems the DMC11 device is supported in the KS10 emulation. Could it be posible to use it to DECNETize (and HECNETize) TOPS-10 over simh? I have not been able to find the docs to install DECNET-10 in a 7.04 monitor... Any TOPS-10 hacker around? :) Well, I've done my TOPS-10 7.04 install (plus TSU patch tapes that upgraded it to 7.05), but I've done it on KLH10 (KL10 emulation) with Ethernet support, so things may be somewhat different. At the time I chose KLH10 right because my goal was to have a DECnet-10 node and that appeared (or was?) the only way. Starting with 7.04 (or maybe even 7.03), DECnet sources are bundled with Monitor sources and to have DECnet you just have to build a DECnet-enabled custom Monitor (which you should build anyway). At boot time everything starts automatically: the Monitor calls KNILDR.EXE to load microcode into the Ethernet and then starts DECnet network service (with help by Galaxy, except for FAL streams that are started by OPR). There is a DECnet-10 tape, but it mostly contains software for front-end based DECnet solutions (KL10 only), e.g. PDP-11s in disguise called DN20s and the like. The only useful file from the DECnet tape is NML.EXE which can be found elsewhere too. Anyway, the DECnet tape is BB-X116C-BB and is available on Trailing Edge; there is also a newer BB-X116D-BB, which is somewhat hidden, but can be located using the search by filename function... :P The DECnet-10 manual I'm reading (AA-L413B-TB) says that DECnet starts at boot time without intervention, whatever the interface used (but front-ends have to be loaded). So, in your KS10 + DMC11 configuration all is needed seems to be a DECnet-enabled Monitor with the right pieces to speak to that hardware. The Software Installation Guide lists a bunch of MONGEN questions related to DECnet on KS10s, asking for KMC/DUP or DMR hardware characteristics. A quick Google search seems to confirm that both KMC and DMR are very similar to DMC and software compatible with it. DMR should be a DMC enhancement/replacement. Look for the following in Bitsavers (/dec/pdp10/TOPS10_softwareNotebooks/): /vol20/AA-P379B-TB_TOPS-10_DECnet_and_PSI_Installation_Guide_Apr86.pdf /vol20/AA-L413B-TB_DECnet_and_PSI_System_Managers_and_Operators_Guide_Apr86.pdf The most updated software installation guide can be found here: http://pdp-10.trailing-edge.com/tops10v704_docc/01/10,7/docupd/sig.mem.html HTH, :) G.

2.11BSD and E11

by wilson＠dbit.com

From: Cory Smelosky <b4 at gewt.net> I'm currently having a bit of trouble getting 2.11BSD working in E11 when using the prebuilt disk by neozeed from source forge: Looks like you're booting from tape? And installing onto what disk image? I couldn't find the tape image you're using. I did find what purports to be an RP06 image but it's actually slightly too small for that, so E11 auto-detects it as an RP05 and half of it vanishes. It boots up fine when the type is forced with "MOUNT DB: 211BSD /RP06". Buuuut, Massbus disks are disabled in the current E11 Demo versions. At this point that's an oversight (all but the RP07 are within the Demo version's size limit) so I'll uncripple that for the next release. I can't remember the last time anyone wanted to use the Massbus emulations! Otherwise I would have noticed and fixed this ages ago. Meanwhile if you can install onto an MSCP disk then life will be easy. Thanks for pointing this out! John Wilson D Bit

Unattended boot of RSX is trivial. Ouch... I had the impression that SIMH lacked the TOY needed to boot without that date/time prompt.

Raspberry PI and PDP-11 emulation via SIMH

For RSTS/E at least, date prompting and such. That stuff sits in LB:[1,2]SYSTARTUP.CMD. Get your self (or emulate) an 11/9x, and the date will be correct, and then you edit the startup to not ask the question, or ask it with a timeout... Or else don't worry about an incorrect date at startup. Unattended boot of RSX is trivial. Doh! The file is LB:[1,2]STARTUP.CMD and nothing else.
