On the odd chance that anyone else out there has an Evans & Sutherland ESV workstation and would like an RDC peripheral concentrator (multiplexes keyboard, mouse, dials box and button box into a single RS-422 line), let me know. I have two, but they are missing the 68000 DIP control processor. Otherwise they are in mint condition. It should be easy to find 68000 chips to plug into these puppies. This means you can have your noisy ESV in another room while you sit in comfort in a quiet work area :-). -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>
