Yes, many machines had Turbo buttons (even 8086), and mhz displays. And they might well be clones. I am not going to argue on that one way or the other. I based my speculation on the belly front design of the case, and I notice several IBM specific displays in the image. If the machines were to be running DESQView, they would be 386. If running a multiline BBS application, they could be 8086, 286, 386, or anything else. But based on the age of the image, I'd hesitate to claim anything above 386. I doubt the dual modem machines are 8086 because the CPU simply wouldn't be able to keep up with the IO, so that becomes 286 or 386, and again, more likely 386.
