OK, I have 400 line graphics - but the plot thickens. If you have a VOC in slot 3, try this: $C029:C1 $C0B5:FF $C0B9:FF and you get 400 line graphics. I have not determined which bits are actually needed yet, I only figured this out last night. As someone pointed out before, the flicker on a standard IIGS monitor is really bad, although I have not yet loaded a real picture in, so it may not be as bad as it first seems. $C0B9 appears to be a duplicate of $C0B1. Most probably $C0B8-F map onto $C0B0-7. Now for the good bit - as I mentioned previously, there is a new strange mode which mixes up the locations of the pixel map, the SCBs and the color palettes. I thought I had figured out how to force things back to standard, but not so. So what I have at the moment is 200 lines in bank $E1 of standard SHR, and 200 lines of mixed up wierd SHR in bank $E0 interlaced. Sometimes I manage to get standard SHR in both banks, but not always, and certainly not guarenteed. I have even managed to mix up the order of pixels/SCBs/palettes in several different ways. If anyone figures this out, let me know. It is possible that none of this happens under program control, but only through the monitor. Tonight I will write a driver for The Graphic Exchange, and use my GIF loader to load in some 400 line graphics. I will post the results tomorrow. -- This net: johnmac@fawlty.towers.oz.au Phone: +61 2 427 2999 That net: uunet!fawlty.towers.oz.au!johnmac Fax: +61 2 427 7072 Snail: Tower Technology Unit D 31-33 Sirius Rd, Lane Cove, NSW 2066, Australia.
