Thanks to everyone who sent me addresses for booting the PDP-1134a. Seems I'm gonna need a bit more help though. Still won't boot... Decided to go through all my manuals and check to see if possibly some cards were missing ... What I found out was that I have no idea... This poor thing was upgraded too many times... I needc to know what some of the cards do because I can't find them in any of my manuals and I need to know if I need any other cards to boot it up... So here they go... ------------------------Mystery Cards------------------------ P/N1210711 This card has 44 chips on it and room for another 132... can't figure out what it does though... Here's the stuff off the front of the chips too if it helps any: TMS 4532-20 ZA1033-A3 P8044-P M9312 This one has a 3-wire cable running to the console... Rev D11 0066 I am totally !cxlue to what this one does. Not even sure that is the card number. It's just the closest thing I found... it has 4 26 pin connecters and 1 64 pin connect or in. M7762 This one is connected to my drive cable so I figure it's some controller but I can';t find it in any of my books.. M8267 This one is plugged in next to the M8265 and M8266 cards and has jumpers, connecting it to them. I suspected it was some kind of coprocessor but the chips on it look more like RAMchips... --------------------------The Rest------------------- M9302 M9202 M7856 (2 of them) M7859 M8265 & M8266 And 2 serial connection cards... ---------------------------------------------------- Also I was wondering if I really need to have flip chips in every slot that has a blank place in the 3rd slot from the back... ----------------------------------------------------- I'd really appreciate any info anyone can give me on this stuff. I'm more of a programmer than a tech...

That's the G727 cards you're talking about. However, there are 2 catches: 1) this only applied to normal unibus peripheral slots. CPU backplanes may have dedicated slots that should be left open. The same is true for options like the RK611. 2) There is a 5th jumper needed, the NPG jumper, which is usually wired on the backplane with wire-wrap wire. I'd suggest finding a local PDP-11 hacker who can look at this for you.

Probably a memory board of some >sort. Hoefully, since I see no other memory in this system 8-). Look at the chip number TMS 4532-20, That's almost certainly a memory chip. Probably something like 32K or 8K x 4. 44 chips would be 11 8 bit words or about 88K x 8 bits. Quite reasonable amount for a old 34.... I have seen a bunch of 1. Non-DEC memory cards, this may be one. 2. DEC cards with out the correct part number terry is refering to. (For a variety of reasons, and sometimes I wasn't even involved 8-} .) 3. DEC cards which the only existing (still) number is hidden or imbedded in the screening or soldermask of the circuit. Not many dec cards, especially old dec memory cards had sockets for adding more memory. Unless it said DEC in big red letters, I'd suspect it was a aftermarket. al -- Al.

Still won't boot... Sounds like all the boards below are what you need... assuming you've got a good boot disk pack. I'm posting rather than mailing so anyone else with these great antiques can get some of the info... The notes were in the attic and it's 90 degrees -- so I'm not going for the old DEC Field Service notes from my 79J days - so here goes from memory... >P/N1210711 This card has 44 chips on it and room for another 132... > can't figure out what it does though... Here's the stuff off > the front of the chips too if it helps any: TMS 4532-20 > ZA1033-A3 P8044-P You got me - sounds like some kind of memory board... It's not a DEC part no. Probably TI memory. >M9312 This one has a 3-wire cable running to the console... This is a bootstrap terminator card with connections to the front panel boot switch. This holds the boot roms and front end terminator chips. The space for this is usually in one of the first slots from the right... I think the 4th or 5th (*if my memory is right)... It's marked in the box. Usually the console DL11 sits below it since it goes in the A&B backplane slots. The DL11 goes in the lower 4 slots C D E and F... >Rev D11 0066 I am totally !cxlue to what this one does. Not even sure that > is the card number. It's just the closest thing I found... > it has 4 26 pin connecters and 1 64 pin connect or in. No *&^%$ idea what this is. >M7762 This one is connected to my drive cable so I figure it's some > controller but I can';t find it in any of my books.. RL11 RL01/RL02 disk controller I believe. It's got a flat ribbon cable... Cable goes to a black transition connector and then to a round 40 pin cable I think... >M8267 This one is plugged in next to the M8265 and M8266 cards and > has jumpers, connecting it to them. I suspected it was some > kind of coprocessor but the chips on it look more like > RAMchips... The machine has Cache and Floating point capacity... If it goes in slot 3 or 4 it's cache or floating point. The over the top connectors connect floating point usually. Cache has some red toggle switches to enable/disable 1/2 of the cache on cache errors. >M9302 Unibus Terminator - Put this in the last slot to the left on the bus in the A&B connectors. Otherwise - you can induce smoke. >M9202 Unibus jumper from one backplane segment to the next. Also in the A&B connectors. >M7856 (2 of them) DL11W serial card/clock card... >M7859 I seem to remember this as an LP11/LS11/LA11 printer interface (Data Products). >M8265 & M8266 CPU cards Slots 1 and 2 (rightmost slots)... >And 2 serial connection cards... >Also I was wondering if I really need to have flip chips in every slot that has a blank place in the 3rd slot from the back... Yup they provide grant continuity for the Unibus. Pull one and the bus locks up. The signals must go to the end of the bus to the M9302 terminator. Give me a call one night and I can talk you through some of the stuff on this machine. I did 6 years of DEC service and have some of the info in the attic.
