We offer an 800 X 600 color or grayscale capable terminal that connects to the 386 via fiber optic cable (no ethernet necessary). What you need is: 1. A LightAdapter, which is SunRiver's I/O board for either AT bus or microchannel; supports up to 4 terminals. 2. A cable, available in pre-terminated lengths from 25 to 1000 feet. 3. A SunRiver terminal (FOS800). 4. If you're using Interactive 386/ix, you already have SunRiver support in the package. If you're using SCO Open Desktop, Developers can get Open Desktop drivers from SCO, or from SunRiver if not yet generally available from SCO. We just completed an installation at a Nuclear Power Station using 4 SunRiver Display (for a total of 5 X servers including the host's vga.) The software (standard from Interactive) worked flawlessly. However, I would recommend some serious horsepower to drive it since the SunRiver are 'dumb' display and rely on the host's cpu to do any drawing. Fortunately on this system only two X servers will be operational at any given time. We put in a 25MHz '386 with 14MB, with upto two servers the performance is resonable, with three servers it's slow but acceptable, with all five it is unnusable (I will have to admit we are doing some heavy math/communications in the background as well... with no servers the idle time is 60% average as reported by sar) Take care, Garry. -- Internet : work - pax@megasys.com home - pax@ankh.ftl.fl.us USNail : Megasystems, Inc. 2055 South Congress Ave, Delray Beach, FL 33445 UUCP : {gatech!uflorida!novavax!ankh, mthvax, attmail}!megasys!pax Voice : 407-243-2405 Data: 407-243-2407 Fax: 407-243-2408 Telex: 156281499
