Hello all,
I have a TSENG 4000 VLB video card, and while it does work, the image displayed is very dim. A CRT deals with it a bit better than an LCD, but it is truly hard to read - the text isn't blurry, if anything it seems gray. I have not found the card on Stason

(my rev anyhow) and I have moved some jumpers around but no change.
Now, the card looks like it's been around, the contacts are worn, but none seem damaged. I ran a white eraser over them to clean them up, they don't seem corroded. I also reseated the BIOS chip and the socketed chip beside it. I have also tried several VLB computers in which my other cards work fine.
It seems to me that it's a low signal issue. Is it the DAC or one of the caps perhaps? What should I try?
I'd like to get this going so I can do a benchmark of two systems that have integrated CL VGA cards vs my new Mach 32 vs this 😁
