It worries me since I am planning to get one. Is this true? No. The Series II is DMA, and a very good DMA controler at that. Your friend is thinking of the older, "Impact" line that GVP manufactured before the Series II. That controler was a decent non-DMA design that used a large buffer. Unfortunately, GVP muddied things up by calling it "DMA to an on board buffer" which was marginally true but very misleading. But that was then. The SeriesII is real, live, DMA controler. Now, does anyone know if the claimed "dual ported" ram on the Series II 0/8 is also a deception? I didn't know that made dual-ported simms.....
