Pinpoint manufacturer - Tseng Labs ET4000AX ISA

[B.afzelii]

Hallo,
I have a Tseng Labs ET4000AX ISA card with no direct manufacturer coding; at least I can’t find one.
It seems to be a reference OEM product or an original Tseng Labs card? The circuit board has the dating 1-16-90 printed on it,the dating on the chips are from 1991(production date).

Part number is 8925 A. REV 5

Thanks in advance!

Wow, haven't seen one of these in a very long time.

I'd guess it's original Tseng because of the bios sticker and because it says Tseng on the edge on the back of the pcb.

I'm no expert though and it's been a while since I played around with these champions of the ancient days

It was one of the fastest VGA cards of the DOS/Windows 3.x era.

The thing really seems to be an early ET4000AX card, directly manufactured by Tseng Labs. The layout is similar to a Orchid ET4000AX card. Except the chip dating , which dates 1992.

From Wiki
Tseng migrated from a retail / commercial board supplier to OEM sales of their chips. Ultimately, Tseng Labs VGA controllers were found in PCs from major system and board companies including Compaq, Dell, IBM, NEC, STB Systems, Diamond Multimedia and several major Taiwanese add-in brands

I remember going from an unaccelerated card to an tseng et4000. From this horrendous slow scrolling in word to like 3000 percent as fast.
Talk about productivity improvement at that age.
Stellar card and pretty cheap also when i bought mine.

Awesome...I use a PCI Tseng Labs ET6000 4MB as my MS-DOS pure 2D accelerator.

+1 I've got one paired with 2x Canopus Pure3D IIs in an old gaming rig
