Unknown Mobius Color Video Card for SE/30

[mshefa]

Hello all,

I just bought an SE/30 at a flea market and when I opened it up, I found a Mobius card that I don’t recognize. I have attached photos. The model number is MD012 Rev A and the date is 1991. The computer’s hard drive still worked and I noticed a bunch of color control panels installed. Please see all the photos. Does anyone know what this is or can anyone point me to where I can find out?

Much appreciated,

Mason S.

FWIW, the "Monitor" control panel photo is of the computer *without* the Mobius card installed.

Very nice find!

Back up that System Folder immediately! The Color Switch control panel and any other drivers for the card need to be preserved. Most of what you need will be on the Declaration ROM of the card, but it looks like you need that custom Control Panel for full function. After backing up, install the Mobius VidCard and see what options become available. Also run TattleTech to see what info pops up about it in the PDS/NuBus report.

As far as that connector plug goes, it looks like your SE/30 was paired with a Full Page Display. It'll be interesting to see if that's a terminator block?

Search the 1991-1992 issues in the MaUser/MacWorld archives for more info on your card. Mobius is a pretty good search term. Good luck!

Trash, thank you very much for your suggestion and insight. I searched every single issue from January 1991 to December 1994 and did not find a single mention of a Mobius card that was not the 030. I wonder what this could be! I don't have a way to load programs onto the computer yet—the floppy drive is inoperable. That also prohibits me from backing up the files. I may need to invest in a Floppy Emu soon . . . .

You're welcome, I'm surprised you didn't find anything. If you have another Mac and a printer cable you can do a baseline AppleTalk connection between them.

Took a whack at June 1990 MacUser, found two listings:

That card isn't going to do any colour.
Probe around the output pins if you can find signals that look like VSync, HSync and Pixel data and you should be able to wire them up to an analog multisync monitor. VSync and HSync are TTL anyways on VGA monitors, you just want to run the pixel data output through a resistor divider to get the voltage down to VGA levels.
