Unusual "Memory Plus" SE/30 video card

[Realitystorm]

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.

@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.
