Up for consideration is a vintage Union ESS ISA sound card with the ES1869F chip onboard supporting ESS ESFM and SoundBlaster Pro compatibility. These are great sound cards for DOS retro computer builds as they sound good and have great compatibility. This one is in good condition and was recently tested to work well. It also comes with an original driver CD as well. This will be carefully packaged and shipped via USPS Ground Advantage. Thanks for looking!
