content: Hi,I got a free SGI indy but I need a video cable, I would rather build a cable than pay $30 delivery for a used cable that I will have to destroy.I can see the 13W3 connectors on aliexpress but they are the "high power" versions, the below link mentions "size 8 slots" for either coaxial or power contacts, has anyone got any idea if I can easily source these size 8 coaxial connectors?https://au.rs-online.com/web/p/products/1600443/?grossPrice=Y&cm_mmc=AU-PLA-DS3A-_-google-_-PLA_AU_EN_Connectors-_-Usb_And_D-Sub_And_Computing_Connectors%7CSolder_D-Sub_Connectors-_-PRODUCT+GROUP&matchtype=&gclid=EAIaIQobChMIn9yEx9vH3AIVU6aWCh1bWQCKEAkYBCABEgI9rvD_BwE&gclsrc=aw.dsThanks.Richard

content: There are adapters out there too. Careful though, SGI and Sun use the same connector but a different pinout, I don't recall the details but I know the Sun adapter I have didn't work on the SGI boxes I used to have.

content: Someone in this lovely community must know where I can get this.I found a "Handmade-SGI-13w3-to-VGA-Cable-Adapter-with-H-V-Sync-Routing" on Ebay but it's A$70.He must have found a source of 13W3 connectors with the coaxial inserts...Any idea how the 13W3 RGSB could be wired to VGA RGBS, this:https://electronics.stackexchange.com/questions/255404/creating-a-rgsb-to-rgbs-converter

content: I have made a couple the Sun versions of these in the past to adapt Sun monitors to a normal PC VGA port. One was made with a (female i think?) connector salvaged from a Sun video card to run a monitor with a captive 13W3 cable, the other used a 13W3 -> 13W3 (male to male?) cable which I cut one end off to replace with a DE-15 VGA connector. If I still had this then I'd throw it in the post but I'm afraid it went in the skip long ago.The end of this thread has a couple of links which may be useful:https://www.eevblog.com/forum/testgear/connecting-hp8568b-and-hp8444a/Also I second the suggestion to look at adapters - they are probably the cheapest option given free china-shipping and you may be able to deal with any Sun/SGI pinout differences on the DE-15 side.

content: Digikey has these connectors, you can sometimes change the inserts from power to coax with an extractor. If you don't mind a ghetto cable, you can crimp a 75Ohm coax cable with the inserts and plug them directly without the shell. They are almost compatible with SMB 75 Ohm connectors..

content: Quote from: Hydron on August 01, 2018, 01:20:10 pmI can't see any 13W3 adapters from China with free shipping on Ebay or aliexpress?The cheapest adapter on Ebay is A$26 and its all moulded into a single housing with no interconnecting cable.With the 13w3 connectors from Aliexpress and three pins from Ebay that comes to A$12 but i would need some coax, do you all think this is too much hassle?Ideally I could buy the pins cheaper in bulk, A$2.25 a pin makes the three pins more expensive than the 13w3 connector (with 3 high power pins included)!
