Trident 8900B ISA Video Card (TMI 4820?)
Trident 8900B chipset, fitted with 512KB RAM.
Tested & working.
However please note that on an LCD monitor there is some vertical banding - I'd describe it as "moderate" on this card. Ie, it's not as terrible as many others I've seen but it is noticeable. How annoying it is for DOS games depends on the game and type of graphics - see example screenshots. As always with old video cards it's best used with a CRT monitor.
Note: unfortunately the RAMDAC is soldered on this card... installing a socket and different RAMDAC may help, if you can be bothered.
