Looking for Windows 3.1 drives for the following card:

It is quite uncommon card. This one is ExpertColor DSP64300. Some other cards sharing the same chip include Boca Research Voyager and maybe more.

Anyone has them?

Thanks. Generic 1.0 drivers from the above site do seem to work. Although, 24bit isn't stable to complete my tests. 8/16bit work well.

The card showed indeed very nice performance. In DOS it matches high-end cards and trails only Bali32 (ARK1000PV card). In Windows performance is almost S3 864level. At least in 1024x768/256 mode which is nice consider the later is 64bit card. Hope I can 24bit driver working somehow.

I tried with and without the cache DRAM. The benefit is about 15%.
