And is it really > always controller card resident for the 3rd partiers? Not necessarily or even usually on a bus terminator card. On the 11/24, 11/23+ and later Qbus processors (11/73+, 11/83, //53, 11/93), the ROMs are on the processor card. For many Unibus machines, and the Qbus processors that didn't weren't integrated with SLU, LTC, etc, it was often on a separate ROM card or a multifunction (SLU/LTC/RAM/ROM: MXV11-A or MXV11-B) card. The BDV11 used in 11/03 ansd 11/23 systems was unusual in being a combined terminator/clock/bootstrap card (like a TEV11 or REV11 with extras). -- Pete Peter Turnbull Network Manager University of York

This sounds like the Cornell Program Synthesizer developed by long-time Cornell professor Tim Teitelbaum. It was used to teach Pascal to tens of thousands of students at several large universities in the early 80s, on Teraks and perhaps other computers. I think he gets the credit for developing the first practical language-sensitive editor, the progenitor of most IDEs out there today. - John

booting from RQDX3

by engdahl＠cle.ab.com

How does a PDP-11 boot from an RQDX3 controller? I have several 11/23's based on the KDF11-AA CPU, which has no on-board boot ROM. The Andromeda UDC11 disk controller that most of these use contains the boot ROM. These machines are in a 4-slot dual-wide card cage which is full. There is the CPU, a memory card, the disk controller, and a serial card. A couple of these machines are missing the disk controller. RQDX3's seem to be readily available, and there is adequate documentation of the card on the web (jumpers, cable pinouts, etc). Will the KDF11-AA be able to boot from an RQDX3? If not, can anyone suggest an good alternative? -- Jonathan Engdahl Rockwell Automation Principal Research Engineer 24800 Tungsten Road Advanced Technology Euclid, OH 44117 USA Euclid Labs http://users.safeaccess.com/engdahl

dumping dec docs

by oliv555＠arrl.net

Just saved these PDP11 related docs from being dumped. 1st come, 1st served, you pay postage. Priority to individual requests, ie: anyone wanting "all of them" can have all that remain unclaimed after 24 hrs (Sat morning). Not wanting to offend anyone, just going from prior experience and my wish to fill as many individual "want" lists as possible. Please direct your requests off-list to oliv555(a)arrl.net. Thanks. - BM873-YA Restart loader Engineering Drawings (no cover sheet) - DLV11-J (M-8043) SLU Users Guide - FP11-B floating-point processor engineering drawings - KB11-A (11/45) CPU Maint.

Print Set - LP11 line printer manual - LP11/LS11/LA11 line printer manual - (5) MF11-u/up (core) Memory Engineering Drawings one set has the original cover, other 4 are missing cover - MS11-C bipolar memory (1k) engineering drawings - MS11-E Engineering drawings (M-7847) (missing cover) - PC04/PC05 paper-tape reader/punch maint manual - PDP 11/45 MS11 Semiconductor Memory Systems Maint.

SCSI or Voodoo?

by CARL.P.HIRSCH＠sargentlundy.com

That's okay, only 50 meg is going to be Mac OS... everything else will be A/UX partitions for NetBSD! ;) thanks, -carl Douglas Quebbeman <dhquebbeman@theestopinal To: "'classiccmp(a)classiccmp.org'" group.com> <classiccmp(a)classiccmp.org> Sent by: cc: owner-classiccmp@classicc Subject: RE: SCSI or Voodoo? mp.org 06/01/01 12:35 PM Please respond to classiccmp > Assuming that the listing is correct and that it is a > 50pin narrow SCSI drive, it should work fine on the Quadra. However... I *think* you'll need OS 8.1 or later to format a drive that large as a single volume. Formatted as two 2GB partitioned, you should have no trouble using older Mac OS's. Regards, -dq

If he doesn't let go of it, get back to me, I think that's the trash-80 book I pulled off a garbage pile a few years back. It won't be in pristine condition, of course. Just lemme know...
