While I'd have no trouble believing MTS supplied 10-Base-2/T combo cards 
in the early days, I'd have trouble believing their early DSL modems 
actually used coax only.  But that could be the case.  (I'd say you'd 
have to go back quite a bit more than a decade, though.)

Ah, memories!...  In my first few years in my current jobs (almost 25 
years ago now), I did work with some (inherited) 10Base-5 nodes, with 
the old external transceivers and stinger taps.  I don't remember having 
to actually install one myself, however.

We did run 10Base-2 thin coax for a number of years, and I did install a 
number of external transceivers on that, as well as BNC T connectors for 
interfaces with internal transceivers.  This would include running a 
temporary bypass cable (which we affectionately called the "hyper-space 
bypass") between two points, so that we could splice into a section of 
previously "live" cable to install new connectors for new drops.  We got 
comfortable enough with doing this that we could add new drops on a wire 
without anyone on that segment even noticing an outage (except for maybe 
in the room where we were working, which was being bypassed).

Fun stuff...  I don't miss it at all, though.  :)
