Hi, I just repaired the powersupply of my pdp 11/44 and cleaned the box. When powering up, the console terminal only shows: (Console V3.40C) (Program) (Console) ?CP didn't start >>> I guess this is bad news.... Does it mean Central Processor didn't start? (just guessing, but the RUN- light stays dark, DC-LED is on and the key works) Since i don't have a manual for the 11/44 i really don't know where to start. I searched the web for a scanned KD-11-Z manual, but found nothing. The actual configuraton is minimal, I insterted the processor, cache, ram, CIM and bus terminator like this: A - B - C - D - E - F M7090 X X X X CIM / CIS (option) X X X X X X CIS (option) --------M7093-------- FP11-F FPU --------M7094-------- KD11-Z data path --------M7095-------- KD11-Z control module --------M7096-------- KD11-Z multifuncion module --------M7097-------- KK11-B cache --------M7098-------- KD11-Z UNIBUS interface --------M8743-------- MS11-PB 1 Meg Ram X X X X X X MEM (option) X X X X X X MEM (option) X X X X X X MEM (option) X X X G X X UNIBUS M9302 X G X X UNIBUS G=Grant card. I do have the "processor handbook pdp11/04/24/34a/44/70" (printed in 1981, EB-19402-20) and tried some of the console commands. HELP works fine and gives a lot of HELP-text, but doesn't help much: all other commands tell me ?CP didn't start. I tried using the processor without FPU and disabled cache, but nothing changes. All DIP switches and 'Jumpers' (soldered) are still in default position. What can i do now ? Any idea is very welcome.... Regards, Lothar PS: Would it be usefull to anybody to scan the (entire?) processor handbook? I don't know how usefull this book can be to someone else...

What's the value of an rtVAX 4000-300 with no drives?

by glenslick＠hotmail.com

At a surplus store today I saw a couple of rtVAX 4000-300 boxes. I don't know anything about these types of systems. Are they interesting to people on the list? What is their value without any disk drives? They were marked $75 each. They had KA670-BA cpus, which I guess is standard for that box according to some info I just found googling around. They both had TK70 drives and at least one had a TQK70 board installed, which I guess is the controller for the drive. I'm not sure how much memory they had. -Glen _________________________________________________________________ Join the world’s largest e-mail service with MSN Hotmail. http://www.hotmail.com

Multibus ST-506/QIC-02 (was: Re: SGI IRIS 1400 ...)

I once attempted to repair one of HP's HP-IB hard drives used a Vertex drive internally. I THINK it was a V160 but I'm not sure now. I never did find a replacement that would work. IIRC I tried other brand drives but I couldn't LL format the new drive with the normal user stuff from HP so I don't know if the replacement drives were incompatible or ?? or if the replacements failed due to my inability to LL format them. I suspect you'll run into a similar problem. In addition, you'll lose all your SW if you replace the drive. If I were you I'd do my best to get that drive working again. The fact that it spins up initailly is a promising sign. I did look through my HP disk drive notes but I couldn't find anything that told what model HP used the Vertex drive. If you find a useable replacement or manage to resurrect that drive I'd be interested in hearing what you learn. Joe

List Change Updates

by lists＠subatomix.com

The first pages of the new ClassicCmp web site are up. It isn't much, but at least the correct instructions/forms for subscribing are there. Expect more in time. The site will be kept simple and (mostly) text-only, just like its predecessor. Comments/criticism are welcome. A few issues have popped up for people who are subscribed to both cctalk and cctech. To solve these, the following changes will be made shortly. These changes will _only_ affect people who are subscribed to _both_ cctalk and cctech. - People who haven't disabled mail delivery for either list will be unsubscribed from cctech. This stops duplicate mail. - People who have disabled mail delivery for cctech only will be unsubscribed from cctech. This stops off-topic messages sent to cctalk from forwarding to cctech without moderation. - People who have disabled mail delivery for cctalk only will be unsubscribed from cctalk. Other methods are in place to make their cctech posts forward to cctalk. - People who have disbled mail delivery for both cctalk and cctech will be unsubscribed from cctech. This prevents any issues if/when they decide to get ClassicCmp mail again. With the recent list changes, subscription to both cctalk and cctech is unnecessary and can create problems. -- Jeffrey Sharp The email address lists(a)subatomix.com is for mailing list traffic.

NPR and the RX11 (was Re: help needed: problem with UNIBUS ac cess on my PDP-11/70)

by GOOI＠oce.nl

Hi Ethan. Yes, the RX11 (M7846) is programmed I/O only. I checked the RX board yesterday for my NPR problem in the 11/70. Indeed, the pins CA1 and CB1 are *not* wired on the board ... back to the 11/70 thread with this result. - Henk. > -----Original Message----- > From: Megan [mailto:mbg@TheWorld.com] > Sent: dinsdag 16 juli 2002 6:19 > To: cctalk(a)classiccmp.org > Subject: Re: NPR and the RX11 (was Re: help needed: problem > with UNIBUS > access on my PDP-11/70) > > > The RX11 isn't DMA... when you give a command, it reads to a > silo which > the driver has to dump, a character at a time, or writes the > silo which > has been written, a character at a time... > > I just checked the RT-11 RX01 driver source to confirm it... > > Megan Gentry > Former RT-11 Developer

Since I already had a Portable III, hard to turn down another one. The 5 1/4 went out on my first one and I replaced it with 3 1/2, so at least this one is still 'original' equipment. As far as later Compaq gear, give it to someone else, or gut it out for useful items. Mike

Sounded like the drive would spin down, then spin back up, 'chew' on the platters a while, then spin down again. The secret, John, is knowing what you will drool over. ;^) Mike

HP cassette equivalents?

by foo＠siconic.com

Didn't we discuss a while back that HP82167 data carthridges were the equivalent of some other type that is still on the market? These would be for the HP 82161A drive.
