Yup, read it all. The issue was that the jumpers were wrong on the 8900d Card I bought, luckily I found the manual online. Everything is working great now! FYI the ESS Audiodrive is the best soundcard I have found to use on the Tandy TL/3. It doesn't interfere with anything and has great soundblaster support. The setup is a TL/3, xt-ide to CF hdd, Trident 8900d, with an ESS Audiodrive card (1869 model).
