This 16-bit ISA card was one of the fastest around in it's days. Due to a fast host-interface it could transfer data between the ISA bus and the video chip pretty fast.

I pulled this particular card from an AMD Am386DX/33 system and today it's sitting in my 20MHz 286. In combination with the 386DX it was able to run Doom at a fairly good frame-rate. I've seen many 486SX/25MHz configurations that ran twice as slow! Often a good balance between CPU and video chip is important when playing games, even today.
