RT11 runs fine on LSI/11's both in a standalone, but also in some third party networked applications. A company in the Netherlands, Techlan, made redundant token passing network cards for Unibus and Qbus, booting them of a central RT11 server. They went very well indeed in a diskless environment, used for process control by companies such as Outokumpu the Finish mining comglomerate and in conjuction with Gamma 11 systems from DEC/Philips.... so should have run fine on an console LSI-11 Ken Kirkby K.

A little exchange or mcr flx and I'd have the floppy copied. My other method to do the sysgen involved getting sent to DEC training and bringing up an RK pack to do the sysgen with in the lab DEC used for Field Service Training. I did it there for four years. DEC security got too bitchy about it the last time and confiscated the pack so they could check I wasn't stealing VAX/VMS cluster sources on it (someone was caught doing this a couple of weeks earlier) and it became policy that no media went in/out without inspection. Took them about 6 weeks to get me my pack back and the #@$%^& crashed it when they shipped it. I took out the DEC Finance RK05 when I booted it on a PM. The thing had a 1/4 inch bend in the platter where it contacted one of the screws that held the disk pack together in shipping. Damn, I miss the fun of RT11 on the PDT. Nothing like the sound of the Reset and seeks on the RX's. RT11 ran great on the 11/70's -- just that RT11 didn't support it officially. I think they didn't deal with the Unibus map so it wasn't officially supported on the 11/70's. I used to lock down the best 11/70 in the lab by booting my RT11 pack on Sunday evenings. I'd drive up from NJ a bit early playing adventure for a while and run the RT11 light pattern on the best 11/70 in the lab (I'd use RT and the diags to find the machine least likely to be really broken before the Field Service class would whack at 'em). I'd spin down the drive leaving the light pattern from RT running and hang a sign on the box Sunday about 10pm saying Operating System Test in Progress Do Not Disturb. When class started the next morning my machine was tested, staked out and ready for me. I'd boot XXDP and off through the field service classes but reload the RT pack and rehang the sign every night. 8-) Bill Bill -- +---------------------------------------------------------------------------+ | Bill and/or Carolyn Pechter | pechter@shell.monmouth.com | | Bill Gates is a Persian cat and a monocle away from being a villain in | | a James Bond movie -- Dennis Miller | +---------------------------------------------------------------------------+ Article: 21083 of alt.sys.pdp10 Path: iad-read.news.verio.net!dfw-artgen!sjc-peer.news.verio.net!news.verio.net!newsfeed.cwix.com!news1.optus.net.au!optus!news.uwa.edu.au!nntp.waia.asn.au!nnrp.waia.asn.au!127.0.0.1!nobody From: Paul Repacholi Newsgroups: alt.sys.pdp10,alt.sys.pdp11,vmsnet.pdp-11,comp.os.rsts,comp.os.vms Subject: Re: PDP-11 OS Release Dates Date: Mon, 21 Jul 2003 18:11:09 +0800 Organization: none Lines: 33 Message-ID: <87brvojiki.fsf@prep.synonet.com> References: <3F15858A.5799FC92@adldata.com> <4b2dndNoSs4WUYWiXTWJjQ@comcast.com> <3YBAmkv22lwi@eisner.encompasserve.org> NNTP-Posting-Host: zion-a01.conceptual.net.au Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Trace: nnrp.waia.asn.au 1058792847 11159 203.190.192.4 (21 Jul 2003 13:07:27 GMT) X-Complaints-To: usenet@nnrp.waia.asn.au NNTP-Posting-Date: Mon, 21 Jul 2003 13:07:27 +0000 (UTC) User-Agent: Gnus/5.1001 (Gnus v5.10.1) Emacs/21.2 (gnu/linux) Cancel-Lock: sha1:pGaIQ5KHSjN9hfLfrY2eudo5TkM= Cache-Post-Path: grimiore.conceptual.net.au!unknown@dialup-194-67.conceptual.net.au X-Cache: nntpcache 2.3.3 (see http://www.nntpcache.org/) Xref: dfw-artgen alt.sys.pdp10:21083 alt.sys.pdp11:8180 vmsnet.pdp-11:22923 comp.os.rsts:795 comp.os.vms:189701 kaplow_r@encompasserve.org.TRABoD (Bob Kaplow) writes: > In article <4b2dndNoSs4WUYWiXTWJjQ@comcast.com>, "Douglas A.

We used to run the PDP-6 from DECtapes when the disks where scrod... That was real DECtapes though, and quite reasonable. I have also run a 11/44 from TU-58 as the system disk. I can promise you, it is something you never want to do. To init it I set it going, then went to the tavern across the road for lunch. I think that is the only way you can, other wise you will kill off the `failed' init... Light and blunt please, we want it to be *SLOOOOWWW* and painfull!
