I found a little removable chip on a very old video card, On top of it it had a sticker that said "EPOCH"(not sure if it is spelled right), I removed the sticker and under it it has numbers/letters, I assume it must be the part number but i can't easily find it's datasheet anywhere, anyways, here they are:
V765/325
9719
And on the bottom side it has more numbers/letters, They are:
TAIWAN
UTR50849.2H
Any ideas on what this chip could be?
Thanks

Ok, This is pathetic, A day and nearly 100 views, yet not a single reply.
bump.
Probably readers are offended by the more pathetic lack of a picture of the part, replaced by a lousy description.
Let alone.. every time you post, after 10 reads.. you post again and say something like
"omg, 10 reads and no answers?"
I dunno, my first thought is generally, when that many people read my post, and don't have an answer... well, I blame it all on everybody else for not being like Bill Nye the Science Guy and have all the answers!
But really..
If nobody responds.. there's a good chance that they don't know.. or you didn't provide enough information.. it's not the fact that they just skimmed over it and was like Oh.. it's that "ReCreate fellow, let's not answer his question" No need to bump every post because you "must have an answer"
But yeah, a picture might help. 
Haha XD ok, I'll take a picture, though i can't imagine how or why it would help, as i provided everything that is written on the chip.
I can tell you this - it was clearly made in TAIWAN. Hope this helps 
I think i know that XD
Anyways, To satisfy you greedy members (just kidding XD) i took pictures.
Ah. With that size and shape, I think this is somewhat likely to be the ROM/EPROM that holds the "bios extensions" necessary for your video card to be usable by DOS or during system boot. "Obviously" the built-in BIOS of a PC doesn't understand all possible video chips, and it would pretty much suck if you had to get way far through OS install/boot to be able to use the card at all. These "bios extensions" provided a standardized way for an add-on card to supply "standard" functionality to the rest of the PC software.
If that's the case, it's a pretty useless chip - if EPROM, there's some SLIGHT chance that there might be enough empty (and programmable) space in it to use as a much smaller EPROM in some other application. If ROM, you can't even do that. Since there's no "window" it probably isn't erasable...
(there are standard pinouts for this sort of chip. Lookup "27C512")
(See, the picture did get you more responses! It might have been more useful to see it "in context" with the rest of the video card. Sometimes you get clues from other identifiable chips, or the way the chip is connected.)
lol @ Jezuz, thank you Captain Obvious! (I've been waiting to say that!)
But yeah, I would have never been able to answer anything.. even after the pictures! But everyone <3's pictures!
Ok...Here are pictures of the whole card...
I had to edit 2 images, Due to my utterly crappy camera that can't take pictures more than a foot away >_<
If it is EPROM, Can i use it with my arduino?
And will i be able to wipe all the data on the chip to use it all?
I assume that the other chips next to it are video ram, especially the fact that they are removable.

Not easily. If it IS an EPROM it's a parallel access thing with 8 data lines and 14+ address lines, making it awkward to connect.
And will i be able to wipe all the data on the chip to use it all?
Probably not. For a significant time period, manufacturers were offering "EPROM" (programmable and eraseable) chips in a package that didn't have the window that would let them be erased. It made the chip/package much cheaper to manufacture, but preserved the ability to program them "at the last minute."

Yep.
The card pictures isn't TOO helpful, though I would guess from the large "does almost everything" chip that the bios ROM is one of the few pieces left...
We had half a dozen card like that on a shelf at work for a long time. S3 Trios, we chucked 'em out because we got fed up with the space they ate. They probably first saw light of day in around 1997, just so much electronic junk these days.
