Do any other vendors have something like this?  This sounds like something
we could use, and I'd like to check this out.

Optical Data Systems has such a beast.  I'm not sure about Synoptics or
Cabletron.

Cabletron sells a line powered, wall box mounting tp to thinnet adapter that
looks very nice.  I have no experience with it.

synoptics has one also. I'm the hostmaster for SynOptics.com
and use several of them for my DECstation 5100's, which only
came with thinwire.

Contact support@synoptics.com for more information

Hmm, now I could be wrong, but it's my impression that any device with
10Base-T on one side and 10Base-2 on the other must be a repeater, no
matter how small a box it's in.  As such, people installing them
should be aware that they impose a repeater's worth of delay, 
bit-regeneration, etc.  I think calling it a "converter" or anything
other than a repeater is very misleading, since the unwary may think
it's just a balun or something.

The product from AT&T is *indeed* a repeater, as per the specifications
of 10BASET and should figure into the round-trip-bit-delay equation.

Hewlett Packard has a low cost 12 TP port repeater with an AUI port and a 
10Base2 port.
