| Mac SE with Radius Accelerator and Page Two Display wont boot. |
Posted by: BobDaAggie on 2025-12-29 21:06:45
So I have spent Christmas break working on getting my Mac SE up and running. When I got it, the CRT would not come on. I replaced the CRT and the neck board and the Mac SE booted. I have a Radius Accelerator installed and the Mac SE booted up using my external BlueSCSI and running 7.1. I also got a Page Two Display card that I then installed in the Mac SE. Now when I boot, I get the Welcome to Macintosh with the Radius Accelerator logo but it will not go any further. I have not installed any software other than the default BlueSCSI image. I found that there is software for the card but I cannot boot the Mac to install the software. Any ideas? |

Firmware v2.1 should work fine with that accelerator and system 7.1, from memory… but it may be worth trying system 6.0.8 and see if it boots with that? |

Don't remember, but you may need to pull the Accelerator and install the drivers for it first? It has been a VERY long time.
edit: ISTR needing a ROM upgrade for my Radius16 to move into System 7? |

Either/or get it going off the accelerator first then introduce the FPD card later |

So the accelerator by itself worked. I will try installing OS 6 on the BlueSCSI and reinstall the display adapter |

Finally got around to getting os 6 on my BlueSCSI and success!
The accelerator works, now I need to figure out if the Page 2 adapter is working |

now I need to figure out if the Page 2 adapter is working How are you going to do that? |

One of two ways, I have an oscilloscope that I can see if there are video signals coming out of the BNC or I can borrow an RGB-DVI 300A from a friend. Hopefully I can see the signal. |

I’ll be interested to see the results, I have two of these cards (a full page and a 2 page) but I’ve never been able to test them! |

Might find a bit of help here, you'll need to break the BNC connection wire out to R, G and B input lines on the display to get a white background.
The banding on the displays is eliminated nicely by running the signal through an Extron Scaler. |
