| Unusual "Memory Plus" SE/30 video card |
Posted by: Realitystorm on 2025-12-30 13:39:00
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.

View attachment 33620 @mikes-macs The top left image looks a lot like the graphic board I am trying to identify. Do you remember where you found this article? Also what do you mean "standard video drivers" you didn't need a special enabler to use it? |

@mikes-macs The top left image looks a lot like the graphic board I am trying to identify. Do you remember where you found this article? Also what do you mean "standard video drivers" you didn't need a special enabler to use it? I have the same tall SE/30 version of the card as mentioned in one of the earlier messages, I am using System 7.5 on my SE/30 and I didn't have to do anything additonal to the system to get the card to work- I just installed it and opened the monitors control panel, and it picked up my display right away. The card was connected to a cable that went to the DA-15 Macintosh style video connector mounted on the expansion bracket, which I used with a Mac to VGA video adapter (same adapters I use on my IIci, PM 9500, etc.) to connect it to a VGA LCD display I had. |

It can do both. It is that way on a few Radius cards.
It’s not the case here though, so the two ICs aren’t 2018/64s or 3000 series FPGAs.
There are no Xilinx bitstreams inside the ROM dump.
They could be non volatile CPLDs - I think I have seen Altera ones on gear from that timespan. Not sure if AMD MACHs did exist in that size.
Checking GND and VCC pins against a few different CPLD datasheets might give us a hint. This shall answer the unknown FPGA question- my card did not have the labels sanded off. They are TI TPC1010AFN-068C programmable gate arrays. |

Sorry for the delay, I was away. The article was from an extensive search and I believe it was the wayback machine, PC Magazine, early 1990's. I didn't bookmark it so I couldn't find it quickly. I'll keep looking. As I recall it was a big write-up about the Mac Portable, SE, SE/30 and Nubus Macs. No other info was present just what I grabbed.
Standard driver = Mac built-in video drivers
I never found the software it bundled with. Btw, The Gamma control panel found in Macintosh Garden helps this card. |

For the gamma controller do you mean https://macintoshgarden.org/apps/gamma |

oh, wow. Someone linked the software on that page. I'll have to give it a try. Nice hunting on the article.
Yes, that is the Gamma Control Panel that I meant. |

I just tried the Publisher driver and it did not work on mine. |
