Hello Blair, It seems from your description of your video connector that it may in fact be the 3W3 video connector as used on some DEC systems. One list member indicated ... If you try to use a fixed frequency monitor, you must use one that is a sync on green model monitor and that syncs at the correct horizontal and vertical frequencies. If you can determine which model monitor originally went to that system, you might be able to research a DEC or HP model that syncs at the same frequencies at ... http://www.monitorworld.com/Monitors/dec/ http://www.monitorworld.com/Monitors/hp/ While I don't have any spares myself, I recently bought a cable http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1275561813 ^^^^^^^^^....... NOT .......... ^^^^^ Sony made monitors for DEC, HP, IBM, SGI, Sun, RasterOps, Radius, and possibly others. If a monitor has only 3-BNC inputs, it is most probably a sync on green fixed frequency model. If it has 4-BNC inputs, it is most probably a composite sync model ( the only exception I know of to that is a NEC model which also has a HD15 connector in addition to the 4-BNC's ). Any other monitor I have ever seen, other than those NEC models, that is a multisync had 5-BNC inputs. Note however that some 5-BNC input models are fixed frequency ( GDM-1950 and GDM-1952 come to mind ). Generally I have found that the Sony models that have 5-BNC inputs and rotary controls are the fixed frequency type. The models that have 5-BNC inputs and have push button controls ( digital ) have been multisyncs ( GDM-1971 and 2075RO come to mind ). http://www.monitorworld.com/Monitors/sony/ http://www.monitorworld.com/Monitors/radius/ http://www.monitorworld.com/Monitors/radius/0322precisioncolor20.html http://www.monitorworld.com/Monitors/rasterops/ http://www.monitorworld.com/Monitors/rasterops/2075ro20colorgraphicsdisplay… Those monitors that are considered multisyncs should be able to sync up on a horizontal scan frequency as low as, or slightly lower than, DOS's 31.5 kHz. The really nice thing about the 5-BNC Sony models, both fixed frequency and multisyncs, is that they auto-sense, and auto-switch sync types. So even though the monitor has 5 BNC inputs, you can still hook up to just 3 of them if your graphics outputs a sync on green signal, or 4 of them if your graphics outputs a composite ( H and V on the same line, but a separate line than R, G, or B ) sync signal. And of course if your graphics outputs a separate sync signal ( H, V, R, G, and B all on separate lines ) you would connect to all 5-BNC inputs. I use my Sony multisyncs to hook up to and test my DEC Alpha's (SOG), VAXstation 4000/60's (SOG), HP PA-RISC (SOG), Sun's (CS), Macintosh's (CS), and of course, PC's (SS). In fact, my multisync Sony's have worked with just about every type system I have ever tried them on except my SGI Indy's, and that might be because the SGI's 13W3 pin-out might not be compatible with the 13W3 to HD15 adapter I use with the Sun's? It's been very convenient, space wise, to use one monitor to test all those type systems, rather than have to store a different monitor for each one.

I guess if I'd have known from the beginning that the computer would be a '7013 model 530' I'd have been a lot better off. I didn't find the exact manual, but rather one for the '500' series, and though it was published in 1996 (this computer is from 1990 or so) most of the physical stuff still seems to apply. Thanks for the heads up... - Blair Subject: Re: IBM PowerStation 530 Date: Sun, 16 Sep 2001 11:45:29 -0400 From: "Blair J.

Forgive me for dumb questions, but I'm assuming a serial terminal is one of those boxes that I keep seeing that has hookups for mice, keyboards, SVGA monitors, and the like? Also called a 'Terminal Station' I believe... Will this work? I don't even know if I'm asking the right question here, and I could be horribly, stupidly, wrong. :o) This thing comes from 'way back in the day' for me, before I was even interested in computers, so I don't know a whole heck of a lot right now. More research I guess... Thanks again. Blair Subject: Re: IBM PowerStation 530 Date: Sun, 16 Sep 2001 11:49:01 -0400 From: "Blair J.

I've no problems driving around Michigan (I think of driving as a way to calm down, and I end up doing it a lot, especially when dealing with foreign territory in the world of computers) to get my hands on one, but I'm not sure where to look.

Unfortunately, I'm a newbie to ALL of this, and I'm not sure what a serial console is... can you elaborate? would I doubt it has. It was just sitting there, and it doesn't appear that anyone has opened it in a LONG LONG time. As for AIX, I'll figure that out when I can actually use the system. I also read something very brief that this machine would run LinuxPPC or YellowDog (forget which). Any idea if that's true? Thanks for your help. Blair
