I haven't posted in a long time. Hope everyone is doing well.

I bought this tonight (SEE PHOTOS AT BOTTOM) via ebay.

I already have a #9 GXE VLB with the two different types of memory (VRAM/DRAM socketed), which is also seen HERE (taken from http://www.amoretro.de/):

And here is MY card. I've never seen this version I bought on ebay tonight.

Has anyone upgraded the RAM on a board like this before? I see the other "Uxx" PCB markings for the current RAM chips are km428c256j-6 which are Video DRAM, 256KX8, 60ns, CMOS, PDSO40. https://www.datasheets360.com/part/detail/km4 … 20105431932813/
However, I think only those go to the "Uxx" markings, and the E1,E2,E3,E4 might be a different memory (VRAM?) like on other version of the #9 GXE VLB.

What RAM would go where? And I'm just assuming the SMD capacitors would be all the same as the other memory?

Anyone want to take a wild guess on how to upgrade all of memory on this thing?

Possibly the earlier / lower specced model (110Mhz BT485 RAMDAC) mentioned here

Interesting. This is the "crap" version. 🤣

Could probably replace the RAMDAC with a 135MHZ one, or 175MHz/200MHz if I could find one.

Just need to figure out RAM, if its worth it messing around with. Its an interesting card anyways.
