Title: Expanding a Cybervision64 (not 3D card)
Post by: icbrkr on April 20, 2006, 02:31:03 AM

My Cybervision 64 card is a bit anemic with 2MB of video memory on it.  What's the VRAM chip specifications?  I need to hunt down another 2MB and am thinking it shouldn't be *too* hard.

The existing chips on my 2M CV64 are part no. NN514260J-60.  I would guess more of the same type would be used.

A quick google search (http://www.google.com/search?hl=en&lr=&ie=ISO-8859-1&q=vram+514260) brought me to the chip directory (http://www.xs4all.nl/~ganswijk/chipdir/f/dram.htm) where they're listed as 256Kx16, Fast Page mode.  The problem is that you will need to find right type of chips to fit the sockets.

Good luck.

I just went to a junk PC salvage yard and looked for some S3 Virge cards with the same memory in sockets.  Popped them into my card and viola 4MB!

Sounds like a plan, I was hoping I could do something like that.  Now, off to find some old video cards...
