Hmmmm... I have two Sportsters. One is a 33.6 model (product code is
000839-07), which uses a 9VAC supply, 1000ma, labeled USR part number
1.015.1286. The other one is an older 28.8 model (product code is
000839-01), and it uses a 20VAC (!) supply, 500ma, labeled p/n 1.015.1202-B.
Neither modem has any marking stating its power requirements. Sweet. The
plugs on both are very similar, both black banded 5.5mm female, but the
center hole is 2.1mm on the 20V supply, 2.5mm on the 9V supply. Just a
quick peek at the Jameco catalog looks like their equivalent part number for
the 9V supply is 157041 for $5.95 (caveat emptor... I can't confirm this is
a working replacement, it just looks right).
