I saw a demo tonight of a Mega ST card that drives any multisynch monitor capable of 50 Khz horizontal scan. Here is the information from a product data sheet: Image Systems Ultra-High-res Display Adaptor 1024 x 768 non-interlaced, 16 colors from a palette of 4096 1024 x 768 "Duocromatic" mode -- monochrome monitor or two colors on a color monitor. Optional 68881 math coprocessor BLiTTER supported Introductory dealer price $500 Image Systems Corporation 11543 K-Tel Drive Hopkins, MN 55343 voice (612) 935-1171 FAX (612) 935-1386 WATS 1-800-IMAGES0 The setup was demonstrated on a 16-inch Nanao FlexScan 16-inch color monitor. It happened to be sitting next to a Mega equipped with an 18-inch Viking Moniterm I. The image quality was quite comparable. The Nanao monitor was said to cost around $1,000, making the whole 16-color setup roughly equal in price to the monochrome Viking. Image systems has its own line of larger and more expensive monitors, too. The screen driver software apparently is still in development. A couple of guys were trying to demo a program they've written to create digital embroidery masters for a computer-controlled stitching machine, but they weren't able to get the color system working with it (I did see the software work on the Moniterm). However, they were running a GEM-based assembler on the Image Systems color machine, and it worked fine. I didn't have a chance to test the big color screen with much software. However, well-written GEM programs seem to work. LakeTerm, a very basic GEM communications program that I wrote with Sozobon C, looked fine. I would expect that the same programs that die on the Viking (such as Tempus) also would die on the Image Systems display. MicroEMACS 2.19, jShell, UUVIEW and UUREADER all looked good. I didn't count how many lines were displayed, but the field of view was huge. I noticed a problem on both the Image Systems setup and the Viking Moniterm when the built-in VT52 emulation routines were called upon to scroll the display. That's a LOT of pixels to move, and the rewriting of the screen was quite apparent. On the other hand, with a display that big, you don't *need* to scroll so often. -- Steve Yelvington at the (almost frozen enough to skate) lake in Minnesota UUCP: ... pwcs.StPaul.GOV!stag!thelake!steve
