Identifying a Motolora chip - MC14544?

by jplist＠kiwigeek.com

Howdy folks; I'm trying to identify a Motorola chip for my father - his guess is a 300 baud modem... The chip comes from circuitry which allows folks to remotely control the lights on a runway. All of the breakers/generators are in a little shed at the end of the runway, but there is a controller board in the tower to allow you to turn on lights without having to trek down to the shed... Unfortunately said controller is broken, and my old man has tracked it down to this chip. Any help would be greatly appreciated; Particularly since the people that own the property have sold off the end of the strip to a local farmer who keeps cows there... And the other pilots are a bit too soft to leap the fence and wander through a herd of cattle in the middle of the night just to turn on the lamps... Thanks! JP

BA123 and disks (RE: QBUS SCSI card...)

by Fred.van.Kempen＠microwalt.nl

True, the various ESDI disks are proving to be a fine and reliable replacement for the RD drives, using the same form factor. My MV4 (in a BA123) has three Hitachi drives, 680MB each, and are emulated as RA82's. Nice, reliable and _fast_ ! These drives, and the controllers (Sigma, ADC, Emulex, Dilog) are real cheap now. --f > -----Original Message----- > From: Mail List [mailto:mail.list@analog-and-digital-solutions.com] > Sent: Monday, February 24, 2003 4:38 PM > To: cctalk(a)classiccmp.org > Subject: Re: QBUS SCSI card... > > > Hello Gene, > > Even though RD-5x fit in there fine, what is probably an inexpensive > but more reliable solution than the RD-5x is to go with 5.25" FH > ESDI drives as some other "personal users" have done.

Info wanted: IBM vacuum tube digital computer demonstrator

by rigdonj＠cfl.rr.com

Yes, that's the item but I'm pretty certain that he's wrong about it being a field engineer's test set. A couple of list members have tracked down several of these but no docs yet.

M9312 Bootstrap Questions

by GOOI＠oce.nl

Well, my 11/34C has the M9312 in it. See www.pdp-11.nl and click on the folder PDP-11/34A. Inside that folder is a folder called CPU information, in there is the folder options, and the last item is the document "bootstrap" (M9312). Maybe that's a little help. I have a scan of the M9312 manual and also of the M9301 manual wich will be at Jay's in a few weeks ... - Henk. > -----Original Message----- > From: Andreas Freiherr [mailto:Andreas.Freiherr@Vishay.com] > Sent: maandag 24 februari 2003 13:49 > To: cctech(a)classiccmp.org > Subject: Re: M9312 Bootstrap Questions > > > Jeffrey, > > are you sure the 11/34 manual is talking about the M9312? - I seem to > remember that my copy describes the M9301, of which, IIRC, there are > -YA, -YB, and -YF versions. > > Since all M9301s are completely different from the M9312, it > would be no > surprise if you cannot match the switches between docs and hardware... > > Andreas > > Jeffrey Sharp wrote: > > Ok, I got my PDP-11/34 mounted in its rack and have started to audit > > jumpers, switches, etc. I am being cornfused by the M9312 bootstrap > > terminator module. > > > > First, I'm confused about what version of the module I > have.

QBUS SCSI card...

by mail.list＠analog-and-digital-solutions.com

Gene, I took a look at the CTP dealer listing index, and the current listed prices for UC08's run from a low of $300 to a high of $750 Out of the 12 listed that have prices showing, the average is $511.25 There was a UC07 recently on eBay in the UK that sold for GBP 252.00 (currently approx. US $397.91 ) EMULEX UCO7 Q-BUS SCSI CONTROLLER FOR DEC http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1247&item=2307510324 With variations in exchange rate, that US equivalent was about $420 on the day it closed.

Transitional Technology Qbus SCSI controller

by mail.list＠analog-and-digital-solutions.com

Hello, I just received this inquiry from a "personal use" user about a card that I am not familiar with. If any of you want to help him out, his address is included. Wasn't someone asking about a differential scsi controller lately? If he'd have better use for a single-ended, and someone else needed a differential, perhaps you'd have a trade. Best Regards From: Robertdkeys(a)aol.com Message-ID: <54.b0c1e41.2b8b0e5b(a)aol.com> Date: Mon, 24 Feb 2003 00:57:47 EST Subject: QTD-1 qbus diff scsi board - you folks know anything about??? Since you folks deal in legacy qbus things, I was wondering if you might know anything about a Transitional Technology, Inc., model QTD-1 differential mscp/tmscp scsi controller? I have one that a friend sent me, to use in an MVII machine, but I can't seem to find out any information anywhere about the board. It is dated 1989, but must have been made by one of the lesser qbus card manufacturers. If you know anything about this particular board, I would be most interested in finding out the particulars, so I can get this thing running. Thanks R.D. Keys robertdkeys(a)aol.com

PDP11 - RQDX1 standalone format utility?

by chpap＠ics.forth.gr

I would like to do a bad sector scan on a RD52 connected to a RQDX1 controller (The machine is a pdp11/73 without OS) prior to installing BSD2.11.Is there a standalone program like zrqch0(standalone version of zrqc from the xxdp package - only for RQDX3) that can be downloaded directly to the pdp via vtserver and recognizes the RQDX1 , i.e. a version of zrqb or something similar?
