[comp.sys.ibm.pc] Documentation on Tseng Labs ET4000 chip

inger@vaxa.aud.auc.dk (inger lytje) (10/01/90)

Hi there !

I am desperatly looking for documentation on the Tseng Labs ET4000 vga
chip. Tseng Labs seems to be unknown to every danish chip distributor,
so i am trying the net for the question:

 Does anybody have (and want to share) the docs for this chip ?
 Or does anybody have the address of Tseng Labs INC. ?


Please post the answer, because i guess many would like this info.

The project should lead to a graphics engine for unix, supporting the
high-resolution modes of most VGA cards, which currently isn't supported
by the unix vendors. It should not be nessesary to mention that i will
share this engine with the net !?


                     Many Thanx
