[Simh] Revised FP11 debug
I'm looking for suggestions on how to test the revised FP11 efficiently. I wrote it so long ago that all my hand tests have vanished. Bitsavers has a set of paper-tapes for the 11/60's FP unit, but no listings. XXDP FP diagnostics are white box tests, intended to check out the logic paths of the actual implementation. I need black box tests that work from the specification, without knowledge of the implementation.

[Simh] rsx11m-v3.2
I am going to try once again with simh's pdp 11/70 setting generating the rsx11m-v3.2. From this page I mentioned before. http://home.earthlink.net/~n1be/pdp11/PDP11.html I was about 10 yo in 1979 so I don't remember these machines. But the pics I see they looked like beauties to behold. So does anyone with any experience in this want to give me any tips? I am going to follow directions from this page as far as I can understand.

Depends on what kind of tips you want. The instructions are pretty detailed, and pretty accurate. If anything, I would suggest generating a system with more memory, larger disks, RSX-11M-PLUS instead of RSX-11M, and a more current version.

Hi Bill, Your previous efforts were tangled up with the question of the platform you were using and the configuration of that platform. Simh will run on essentially all modern OS platforms, but the example you've pointed at was a Linux Desktop system (I.e. one with a GUI display environment configured running the X-Window system). Start from that and follow the directions in your recipe. - Mark ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
[Simh] rsx-11M-v3.2
I find the part of the page that involves simh setup confusing. it mentions a config file. I know where no config file is. It looks like the gzip'd files are above a directory called X. then run.sh shell script is run. The simh varialbe will need changed to the parth to the pdp11 simh emulator. I'll see what I can get done. Bill ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
Re: [Simh] Revised FP11 debug
Thanks, Don. Good to know who wrote the tests! Bitsavers has listings for 3 of the 5 11/60 FP tests, so I'm not sure whether it's usable. I'll try the 11/34 version, as you suggested, although I don't have paper tapes for that, just an XXDP pack (somewhere). /Bob On 3/25/2015 4:49 PM, Don North wrote: On 3/25/2015 8:52 AM, Bob Supnik wrote: I'm looking for suggestions on how to test the revised FP11 efficiently.

Thanks, /Bob Supnik ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh Hi Bob long time, The 11/60 FPU diagnostic listing are slightly mis-filed on bitsavers, they are under the CPU directory: http://bitsavers.trailing-edge.com/pdf/dec/pdp11/1160/ Rather than in the diagnostics directory as they are for the 11/34: http://bitsavers.trailing-edge.com/pdf/dec/pdp11/xxdp/diag_listings/1134/ That being said, the diagnostics (I authored the 11/60 FPP diagnostics a long time ago...) are by their nature implementation and hardware specific, especially the 11/60 FP11-E specific diagnostics. Some of the system exerciser diagnostics take a bit more abstract architectural view, but still are tuned to the specific hardware implementations, as that is what manufacturing/field service wanted (and they paid for the diagnostics). It would have been nice to have architectural test suites for CPU, FPU, MMU subsystems that would validate that engineering did indeed build a new PDP-11 that behaved like all other PDP-11s, but those were not tests that existed back then (late 70s/early 80s when I was at DEC) but may have come along later in the 80s/90s with the advent of the F11/J11 silicon. I don't know about that, after my time. The CIS diagnostic test CZKEExx was a bit different; it really was a white box test that only looked at the spec and not the specific implementations. It had an instruction emulator and compared expected results from software simulation vs real hardware. It also built in a large number of tabled test cases of known results. Based on the diagnostics info available I would suggest that there is more detailed documentation available on the 11/34 FP11 implementation and diagnostic listing than those that exist for the 11/60, so using the 11/34 as a baseline may be more productive.
