Documentation for SE/30 graphics card needed

Posted by: retrofreak83 on 2023-10-16 12:31:19 Hello all, One of my SE/30s came equipped with a graphics card (and even more (?)). There is very little information on or about it. The two only parts of information is: The PCB says: MEMORY PLUS COGAM-4 REV B on it, and there is a EPROM, labeled: Color SE30 A13 - IPT I would to know more about this card, e.g. if there is any software for it, or documentation. At least, I would like to know what I have here exactly 🙂 I successfully managed to get an output using a Mac/VGA DB15/HD15 adapter, but regardless what I set it to, 640x480 was the highest resolution I got. Maybe the card is not able to do more? Any help/information is appreciated 🙂

Posted by: mikes-macs on 2023-10-16 12:40:43 I have one of these in my SE/30. 640x480 256. Works well with Mac OS 7.5-8.1. I have not found software for it so I'm using it with standard Mac video drivers. This is what TattleTech 2.5.8 says about it. • Display# = 2 ◊ Active = Yes ◊ Main Screen = Yes ◊ Color Device = Yes ◊ Type = CLUT Device ◊ Driver# = -51 ◊ Screen Size = 640 X 480 Pixels ◊ Resolution = 72.0 X 72.0 Pixels/Inch ◊ Pixel Depth = 8 (256 Colors) ◊ Max Pixel Depth (Installed Memory) = 8 (256 Colors) + Mem Req for This Depth = 307,200 Bytes (0.3 MB) ◊ Mem Req for 24 Bit (Millions) = 1,228,800 Bytes (1.2 MB) • Nubus/PDS Slot# = $0B ◊ Board Name = Generation X V/30A ◊ Board ID = 548 ◊ Vendor ID = Generation X ◊ Revision Level = Alpha 1.0 ◊ Part# = V/30A ◊ Functional Resources : + Device sResource Name = Color_Virtual_Display - Device Category = 3 (Display) - Device Type = 1 (Video) - Device Software Interface Type = 1 - Device Hardware Type = 1 - Device sResource# = $80 - Driver Number = -51 ---------------------------------- • Nubus/PDS Slot# = $0E There was a post here in which members wanted to know what the writing on the 2 dies says, that is usually sanded off for some reason.

Posted by: mikes-macs on 2023-10-16 20:35:55 BTW, there is a control panel titled "Gamma" that helps improve the display quite a bit with this card. 256 shades of gray is possible on certain monitors.
