I wasn't trying to be exhaustive in cataloguing them all, but to give a quick knockdown about the range. I have also an older model of Asanté desktop EN/SC adapter, 4x8x1.5in and about 1lb, with two DB-25 ports and a SCSI ID selector switch (instead of using a fixed ID=6), an AUI and a BNC port. This one certainly needs the 12V AC adapter. The others that I referred to are of the small (2.5x4.5x1in) form factor, which Asanté also used for LocalTalk adapters.
