Hi everyone, been going through some similar threads but still not finding a clear solution. I have an SE/30 with a Radius pivot se/30 display card and I’m trying to use it with my Macintosh portrait monitor. I have the proper cable (db15-13w3). SE/30 has had logic board, analog board, and psu recapped and works well on its own. The monitor is not being detected in the control panel and it looks like theres a resolution mis-match but maybe some image trying to be displayed? Attached is what I’m getting on the portrait display. Also, when I turn on the portrait display, the se30 internal screen flickers.

I believe the Radius and Apple portrait gubbinses are not cross-compatible with one another.
I was going off of this post which claims the Radius cards are compatible: https://68kmla.org/bb/index.php?threads/se-30-portrait-display.43193/post-470330
The 13w3 cable is an original apple branded one. It is DB15 -> 13w3. I have a vga monitor, is there a db15 -> vga cable that would work?

oh, then I'm probably wrong. Sorry!
Thanks, is the driver this one? https://macintoshgarden.org/apps/driver-radius-pivot-card
I saw some downloads for RadiusWare and Radius System Software but neither of them mention the SE/30 like the first link.
Also my OS is System 7.1, could that be a factor?

Thta blue Radius logo screen means the init code from ROM didn’t run, so Tattletech usually doesn’t show the card either when that happens.
There are sense pins on the monitor connector of the card but they work different from Apples sense pin scheme. If the card doesn’t sense a monitor connection it will hide itself from the slot manager and will basically be invisible to the Mac.
I have a few of those cards too and they only seem to work properly with one specific DIP switch adapter and I keep forgetting what the correct settings are.

Oh hmm interesting, you're saying the db15 output on the radius card has the sense pin on a different pin from the apple standard? I suppose looking at a pinout diagram of the pivot card connector vs a standard apple connector pinout diagram could show me where the discrepancy is right?
Still working on trying different adapter pin combinations, but I was able to install the RadiusWare control panel. Unfortunately upon startup, the radius extension icon has an X over it and then when I try to open it in control panels it says it won't work on this Macintosh. Weird because the ReadMe lists the SE30 as being compatible.
As for the sense pins, I got an adapter that allows you to put jumpers between all 15 connections. Seems like the sense pins are 4, 7, and 10 based on my research. Would it make sense just to try all combinations of those pins until it gets a signal?
