@jextxadore The monitor has a cable that attaches to a computer via DVI, USB 2 & FW 400 (there are 2 FW & 2 USB 2 ports on the back) & the power connection is DC via a transformer pack which has a low-profile power connection. From the iMac, I used a direct Thunderbolt 3 to DVI adapter. The two PowerBooks are a bit different, the 15-inch has a full DVI port, the 12-in uses a mini DVI to DVI adapter cable.
So apart from the way DVI connects to the various Macs used, yes, the same cable was used in all cases.
