Radius Pivot cable and diagnostics.
Posted by: demik on 2020-05-17 11:59:15 Hello, Just picked a couple of Radius Pivots for a few bucks. Model 0194. From my memory, they need a specific video card. Found one on eBay, waiting for it. First issue : no cable in sight for both screens. Anyone got the pinout ? Would a straight DB9 cable work ? Second issue : none of them do power up. No green led, no sound, nothing. Do they have a specific power up procedure with the video card ? From what I found on eBay, they will power up even without a card attached. Any diagnostic ideas ?
Posted by: Iamanamma on 2020-05-19 12:01:18 Is this by any chance the controller card that goes with a Radius pivot monitor? We had one back in the 90's, and I found this NUBUS Video card in our stash, lacking any kind of identification.

Pretty sure that's a RasterOps GPU, It should work in MacII series with RasterOps drivers. Looking at the board layout, it has a 30.24 MHz pixel clock so it sure does only 640x480@67Hz. others clocks are lower so that's the max resolution. It has a nice RAMDAC so probably is a 24 bit card though. Maybe a RasterOps 24si. Pluging it into a NuBus Mac and launching TattleTech will get us fixed 🙂
Posted by: demik on 2020-05-27 12:52:25 Managed to get almost all the pinouts of the monitor. The weird stuff is my Pivot II card is not visible in TattleTech nor Monitor control panel. Is that normal ?
