This is postulated to be due to attractive electrostatic interactions between the leuco form of 6-bromoindigo and wool. the leuco forms of indigo and 6,6′-dibromoindigo has the strongest affinity for wool fabric. Quantitative HPLC analysis of extracts from the dyed fabrics indicates that the leuco form of 6-bromoindigo vs. This information allowed development of a dyeing procedure which is demonstrated to give consistent colors through two passes. The extent of debromination is dependent upon the pH of the dye bath and also the source of the visible light. A dyeing run using 6-bromoindigo alone is found to yield a dyed fabric containing large amounts of indigo, when the vat is exposed to visible light. For the first time, visible light is identified conclusively as a cause of debromination of the leuco form of 6-bromoindigo. □Īnyone here with a CT1600 (which is a good number of you) willing to test out Tyrian on their machine or, by some miracle, has run into this issue before and solved it? Does anyone know what type of sound samples/rate Tyrian uses? I know there are multiple types the Sound Blasters were compatible with but I can't find a full list.Quantitative HPLC and colorimetry are used to study color variations in dyeings with indigo, 6-bromoindigo, and 6,6′-dibromoindigo, the main components of the historic dye Tyrian purple. It's a real shame, the torture this card had to go though, all because of a clueless scrap seller. Worst case, this is some obscure hardware failure which just hasn't manifested until now, and with my luck that's precisely it. I've tried every combination of DMA and IRQ I can think of, and unloaded all of my drivers. (Duke Nukem 2, Jazz Jackrabbit, Jill of the Jungle, Wolfenstein 3D, and Doom, from what I recall.) Every other game I've played up to now has given me no issues. (you can hear the menu selection beeping) But on the SETUP program, I can get them working for just a few seconds before they cut out. OPL music works and sounds great, but sound effects? Nope, zip, zero, nada. But, because apparently I can't have anything good for once, I'm running into more inexplicable technical problems. I played through this whole game on DOSBox before and I wanna do it again on real hardware. I recently got a Sound Blaster Pro CT1600 for cheap and I've been playing several games with it, one being Tyrian, one of my favorite shmups of all time.
