I can tell you that it is definitely possible to blow a 1488 or 1489, because
this klutz has done it. I slipped while plugging the cable into the modem, and
shorted something with the shell of the connector. The 148x got real warm, real
fast, and did so when I powered the machine on later. At least it was easy to
find the problem. :-)
