PDP-11/20 vd one that just says pdp 11 what are the date differences?? OEM?

DEC originally used the /10 designation for a cost-reduced 11/20. They never produced any, AFAIK - I'm pretty sure (without checking) that machine was re-labelled the /15, and those _do_ exist (I used one BITD). According to DEC documentation, the /15 has a KC11 processor, not the KA11 of the /20 (although I've never been able to find out much about the KC11 - I suspect it was a slightly modified KA11); the main functional difference listed is that it only supports one level of interrupt, not four; power-fail re-start is also optional, not standard. I have this bit set that both the /15 and /20 could be had with the 'simple' front console, that that wasn't the differentiator between them. The later /5-/10 pairing does indeed exist - I have one of each. They are absolutely identical except for the printing on the faceplate. Noel

It would be interresting to see if anyone has a "numberless" machine with the "M11-10" designation printed on the back, to see if any was actually delivered (and I wouldn't be surprised if there was /P Well I owned one in 1980 that just said only PDP 11.... but so long ago do not remember the label when I got a chance to swap some stuff for the 11/20 for the museum I jumped at it.

In it there are two PDP 11 model configurations to choose from; the 10 and the 20. For me at least this throws into question the whole "...the 10 first came out with the 5 in1972..." story everyone repeats over and over, unless one must have a "10" printed on the console in order to accept a computer model's existence. DEC must not have sold many original 10 models, and/or everyone who has a 10 does not realize that's what they have. But, facts are facts and the brochure and price guide I have is what it is. Hoping some here will check for themselves and consider it misleading at least to simply call the original PDP-11 a "pdp 11/20 without the nameplate". In short, the original bare-bones pdp11 was the pdp-11 10, the fully-equipped version was the pdp-11 20. Why DEC temporarily dropped it's pdp-11 10 model from the product line and >from newer price sheets I can't say. Certainly the "10" was gone when DEC rebranded their front nameplates to read "pdp 11/20". I believe the 1969 brochure is on bitsavers, or I think my website has a copy you can download. Bill Degnan twitter: billdeg vintagecomputer.net I had heard a rumor the 10 was an oem version!? does that make any sense Bill? Ed#

Vaxstation 3100 - I have console access

by bryan＠bceassociates.com

Hi everyone. I'm hoping that one of the VAX experts out there can help me figure out how to get my 3100 booting. I managed to cobble together the necessary cabling and was able to run a "TEST 50" from the serial console. Unfortunately my Google-fu isn't sufficient to help me figure out what the results mean. Here is what I'm getting below. Any ideas where my problem lies? >>> test 50 KA42-A V1.3 ID 08-00-2B-16-58-20 MONO 0000.0001 ? CLK 0000.0005 NVR 0000.0001 ? DZ 0000.4001 00000001 00000001 00000001 00004001 00000000 00000000 MEM 0010.0001 01000000 MM 0000.0001 FP 0000.0001 IT 0000.0001 SYS 0000.0001 8PLN 0000.0001 V1.3 NI 0100.0001 >>> Thanks, Bryan

or maybe initially they figured to use letters after the 11.... example pdp-11/a pdp-11/E then once out decided to use numbers as a dub designator Ed#

Ok then it definitely defines the date then of a unit. eons ago when I first had started compute exchange in Phx we had one that just said pdp -11 as I remember it came from Sandia Labs.

Looking to buy a Tektronix 405x computer.

by ian.finder＠gmail.com

I've been looking for one of these for ages- I have a lead on a TeK storage tube terminal and will make a trip for it as soon as I can, but I'd love to find one of the computers. I'll pay for one in any condition and shipping from anywhere I can find one. Does anyone have a lead? Please let me know... Thanks, - Ian -- Ian Finder (206) 395-MIPS ian.finder at gmail.com
