[Simh] simh & pdp-8 os-8 forums / help
I have spent about 2 hours trying to figure out why my new simh/PDP8 does not have an LPT device by trying to locate the right forum to ask for help. If this is the wrong place please forgive. Googling does not show any DEC PDP centric forums (So I created my own Yahoo group https://groups.yahoo.com/neo/groups/VintageDEC/info). If you know of any existing forums please pass it on. When I key: LIST TEXT.PA I get the message: LPT DOES NOT EXIST When I start the emulator I have been keying: attach LPT text.txt and no error is reported. Any guidance would be appreciated.

Starting something new on Yahoo is a REALLY bad idea. search for alt.sys.pdp8 (or alt.sys.pdp10, alt.sys.pdp11) for existing USENET discussion groups also available at https://groups.google.com/forum/#!forum/alt.sys.pdp8 ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh

Have you read the OS/8 handbook? It tells you pretty much everything there is to know about OS/8. You can find a copy on bitsavers, http://bitsavers.trailing-edge.com/pdf/dec/pdp8/os8/ I've never used the OS/8 image that comes with simh so I’m only guessing, but it sounds like it doesn't have a device driver for the printer (it's called a device "handler" in OS/8 lingo) installed. You'll need to install one. It tells you how to do that in the handbook. Bob ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh

xkcd aside, besides the info that Alan mentioned, a more help web site for you might be Oscar Vermeulen's PiDP-8 site: http://obsolescence.wixsite.com/obsolescence/pidp-8 He has a very cool PDP-8 running an RPi using Sim-* under the covers. The key is that he has a number of pre-configured OS's set up you can download and examine. Check out: http://obsolescence.wixsite.com/obsolescence/pidp-software--documentation Good luck, Clem Cole On Sat, Jun 24, 2017 at 1:38 PM, Clem Cole wrote: > https://xkcd.com/927/ > > On Sat, Jun 24, 2017 at 12:53 PM, Al Kossow wrote: > >> >> >> On 6/24/17 9:40 AM, Buddy Bell wrote: >> > Googling does not >> > show any DEC PDP centric forums (So I created my own Yahoo group >> > https://groups.yahoo.com/neo/groups/VintageDEC/info) >> >> Great, fragment things even more. >> Starting something new on Yahoo is a REALLY bad idea. >> >> >> search for alt.sys.pdp8 (or alt.sys.pdp10, alt.sys.pdp11) for existing >> USENET discussion groups >> >> also available at https://groups.google.com/forum/#!forum/alt.sys.pdp8 >> >> >> ___ >> Simh mailing list >> Simh@trailing-edge.com >> http://mailman.trailing-edge.com/mailman/listinfo/simh >> > > ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh

That does not mean the OS automatically knows about it. You also need to configure the OS side of things. Seriously - for the OP - you need to start by actually learning the OS, and not just fool around and expect things to just work, or other people tell you the obvious things. The OS/8 handbook is really required reading before you ask any questions where OS/8 is involved.

Johnny Yes Johnny I have looked at a few OSes from DEC days and the pdps 8 and 11 are interesting I think. So I will spend some time with OS/8 and I think tts8 and maybe rx or rsx is pdp8. Anyway RSTS is a descendant of the PDP8 OSes. OS8 anyway. Bill ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh

Anyway RSTS is a descendant of the PDP8 OSes. OS8 anyway. A little confusing text, but from what I *think* you say: RSTS could possibly be said to be a descendant from TSS-8. RT-11 have a very clear resemblance to OS/8. RSX don't really have anything close on the PDP-8 side. The closest would be RTS-8, but it's not very close. RSX comes from the PDP-15 originally. But no matter what OS one wants to play with, understanding the OS is important. Just fiddling with the simh side is not going to cut it.
