I'm wracking my brains trying to remember the slide developing kit I used for a while in the 80s. Would have been during 1985-87. I seem to dimly recall the box the chems came in was mostly black with example photos on the top and sides. Maybe Unicolor? I'm hoping that somebody here might recall what kit it was that I likely used. I'm pretty sure it was a three-bath kit. The chems were liquid, not powder. I do recall that it used blix, and that its temp sensitivity was +/- 0.5 degree F, but I guess that's sort of standard. I also recall that I bought it at a well-stocked local camera store, and not mail order. I lived in Southern California back then and I'm thinking it was probably Frank's that I bought it from. TIA for any help you can provide.
