That's even worse than the old CLtd controllers, they just messed up >1200 baud transfers. The Hardframe and the A2091 and (I think) the GVP Series II controllers are all genuine DMA controllers. They are capable of higher speeds than CPU driven controllers like the Xetec, and do not have to cripple the system to get high transfer rates. Personally I've owned a Hardframe for several years, and have no complaints. It can keep up with the fastest drives, and does not degrade the system's performance at all. -- Blaine Gardner @ Evans & Sutherland 580 Arapeen Drive, SLC, Utah 84108 blgardne@javelin.sim.es.com or ...dsd.es.com!javelin!blgardne DoD #0046 My other motorcycle is a Quadracer.
