Radius Pivot cable and diagnostics.

[demik]

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 ?

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.

Hello,

Thanks but no. 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

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 ?
