Hiya!
For quite some time I have a Paradise WD90C33-ZZ VLB vga in my collection that I am using when testing VLB systems . It works fine but there are several jumpers on board that I have no idea what they do - maybe they are important and maybe the card can be faster or something
I have dumped the BIOS in hopes the header reveals some model number but there is nothing of value there...
I tried searching TH99 and the only thing I am sure is the 4 switches in the back - they control refresh/interlace on high resolutions - but what about the JP1~JP6 settings? Other WD90C33 cards mention that they control 386 or 486 mode, vlb timing, isa/vlb mode (maybe) something called "Date or code status VLB"
I am confused... the other 90C33 cards I found are these :

http://stason.org/TULARC/pc/graphics-cards/C-D/DIAMOND-FLOWER-INC-XVGA-WG-6000VL.html
http://stason.org/TULARC/pc/graphic...AL-CORPORATION-XVGA-PARADISE-ACCELERA-96.html
I am also pretty sure the 2 DRAM chips on the 2nd bank are not used, they are 256kbytes combined and you need to fill all the slots to get a 2MB card, they were installed by the previous owner and I did not bother removing them
Any help/info would be appreciated as I've come to really like the WDC cards 8-)
Thanks!
