Thanks for getting the case correct for DECsystem-10 and that other one :-) When I started managing VAX/VMS on an 11/780 we had two RM03 disk drives and 1.25MB of memory supporting 16 users. It was really important to get more than 1MB of memory to ensure that you got the larger memory boards that would allow expansion to 2 (4?) MB. ISTR that with educational discount our 11/780 cost about AUD$250K in 1982. I guess I’m lucky in that I still manage OpenVMS systems today 30+ years later… Huw Davies | e-mail: huw.dav...@kerberos.davies.net.au Melbourne| "If soccer was meant to be played in the Australia| air, the sky would be painted green"

There's no such thing as running RA81's *Grin* My comments regarding RA81s run something like “we purchased two of the first RA81s in Australia but ran about 15 of the first 100 shipped”. My FS guy and I could replace an RA81 HDA in 15 minutes - we had lots of practice - I think we replaced 10 or 15 in six months :-( Huw Davies | e-mail: huw.dav...@kerberos.davies.net.au Melbourne| "If soccer was meant to be played in the Australia| air, the sky would be painted green"

pdp11/04 : the pics....

I have one of those racks (with the maroon PDP-11 top plate; it came to me with a PDP-11/34 and TS03 in it) but I don't remember the name off the top of my head. ISTR mine has a label with the original system designation for how it was shipped from DEC, but the whole system, not the part of the empty rack. -ethan

Want to tell us more about yours? Does it run? It used to run, until I broke it during VCFe in 2014.. They were sold for a token amount after the ETH decomissioned them, most have been trashed after they stoppped working It will run again one day, just needs some serious time invested. All documentation is there, I have the emulator as a reference, just lacking time. Jos

I have 3 of them. Two of them have the "PDP-8E Mustard Yellow" color. One of those two has the controls and indicator lights for the TU10 on that sloped area at the top. The last one... some "person" spraypainted the top beveled area white (so can't tell if it was the pdp8 mustard yellow or the PDP11 magenta), and then stuffed a DG Nova in the rack. J

Sorry, couldn't resist... -Ali While I am not sure about Doom, it will not run a Quake or Unreal Tournament server since they have x86 binaries in them. I learned this while trying to compile source on my z890 under SuSE. I've seen that machine up for quite awhile so I'd hope they would take a lot less. But if your on the west coast there is this: http://www.ebay.com/itm/182005897801 http://www.ebay.com/itm/172079906457 http://www.ebay.com/itm/182011477001 They recently reduced each piece from 800 to 500 so they may even take less. I assume its taking up too much space for them hah. Its nice you can get a DASD unit too, and while it doesn't have drives the drives should be fairly cheap. Also a tape library if you want. Just an obvious warning that the z890 weighs like 1500lbs or so, not the easiest thing to move, but fun once you have it up and running :) -Connor K
