First post, by yourepicfailure
I've been reading through these boards and others, and well I think I might as well share to help benefit the T3100SX community.
Some folks out there have been wanting a few pics of the proprietary ram card. Well, the fact is, there is not one single design. I have four different versions of the ram card with each also using different sets of dram chips.
Hopefully these can be of use. I couldn't get a perfect focus no matter how hard I tried, so I apologize for the blurriness. But they should be detailed enough to get something out them.

As you can see, each version is of different quality and design depending on the manufacturer. However, Type II reveals the ram modules all use a KEL 8900 series connector. These connectors are actually still manufactured:

The catalog PDF has the most detail.
They appear to be 2 layer boards and each of the modules vary in size. I would not, however, stray more than 65mmx41mm.
If you need additional details, please ask.
My fourth board is a stand-by in the event one of the other modules fail. If someone wants to borrow it for further study, that can be arranged.
