Where can I find IBM SLT card schematics?

[ComputerGeek]

Where can I find IBM SLT card schematics? Not the actually slt chips but the cards that they go on. I've looked all throughout bitsavers.com and can't find anything.
Can someone please help me?

not all-inclusive obviously

Do you also know where I can find a document with all of the cards used in an IBM 360/65, their locations and a diagram of the backplane?

Interesting stuff, Al! So basically DTL/RTL. Love the IBM symbols for transistors.

The closest would be in the Model 65 CPU ALDs, but you would have to derive their locations from the drawings of
each planar unit.

Also, I don't know of anyone with a copy

There is no single backplane in IBM 360 mainframe cabinets, they are in planar sections, connected by flexible cables.
The sections are attached to swing-out frames, and there are multiple frames attached to a framed chassis, sometimes
two deep.

Where would I find the ALDs? I assume in an fe manual?

Each 360 or 370 CPU came with one or more large metal rolling racks which held oversize blue binders (dozens to probably a hundred or more, depending on model) which had the drawings for that particular processor. Whether they apply to any other processor of the same family / model depends on a number of things, like how many of that model were built. For some of the rarer models (95/195, for example) I expect there were no two the same.

Here are - to my knowledge - perhaps the only remaining (complete?) set of schematics, ALDs, SLDs and so on for the System 360 Model 40, in the Hursley archive. For all I know, my dad could have perused these when he was posted there to learn the /40 in early 1964.

You can check them online.

I have a full set IBM S/360 Model 65 ALDs. They are for this machine:

 

[Alsilisk]

Are you the owner of said machine?

Been trying to track down who owns it. Do PM if you are, I would love to ask some questions.

IBM S/360-65 SLT card locations

IBM S/360-65 SLT card locations

Do you also know where I can find a document with all of the cards used in an IBM 360/65, their locations and a diagram of the backplane?

Here is a list of all the cards used in an IBM S/360-65 (as used in an IBM 9020D system) and their locations.

http://ibm360.info/misc/IBM%20360-65%20SLT%20list.pdf

There wasn't a backplane as such. The cards plugged into boards (as in the list above) The diagram below shows how the boards are located on a gate in the frame. This diagram is for a S/360-65 but is slightly different to the layout in the card list. It varied according to options, etc., and I don't have the exact one immediately to hand.



PS: It is "IBM S/360-65" and not "IBM 360/65"

To be even more accurate it is a 2065, at least that's what the badges say.

Yup. 2065 is the name for the processor cabinet. 2365 (of which there can be more than one) is the memory. Once you got into larger configurations or System/370, you had motor-generator sets, PDUs and the cooling system, all of which are parts of the total CPU.

Naming is interesting According to GC22-6820-12 "IBM System/360 Installation Manual-Physical Planning" the full name is "System/360 Model 65 [suffix]" where [suffix] can be H, IH or J, and optionally multiprocessing. Various forms of shorthand notation were used and usually identified the system correctly, if not in an aesthetically pleasing manner.

Ah yes the 370 motor generator... with a plug bigger than my both my fists coming out of it.

The Russell Stoll SC7328 (now 7328-78). It can be yours for only $1000.02 here. Apparently the added 2 cents worth is important.

Trivia: DEC shipped the VAX 86x0 with this same plug, despite all 86x0 configurations being perfectly happy on a 30A circuit. This was during DEC's phase of hiring IBM salesmen and trying to beat IBM at their own game. Which failed miserably for a number of reasons - one of which being these "DECBM" salesmen knew more about the features of the IBM equipment they were selling against than they did about the DEC hardware. Having the 8650 be "IBM plug compatible" with a 370 made no sense as nothing else was compatible - not terminals, disks/tapes, datacomm, whatever. But by this time many decisions at DEC weren't being made by qualified technical people.
