Thanks to the upgradeability designed into the PowerBook 1400, there were
many more CPU options than those. Shortly after release, NewerTECH had 166
and 183 MHz 603ev upgrades available. They also had 233 MHz G3 upgrades for
the 1400 shortly before they went belly-up.

Vimage (from Japan) had 233/512 and 266/1M G3 upgrades for the 1400, and
Sonnet had (and still has!) 266/512, 333/512, 333/1M and 466/1M G3 upgrades
for the 1400 series.

Well, then I suggest you swap the batteries. G3 CPU's don't use much more
power than 603's, so battery life isn't impacted much by upgrading a 1400 to
G3. In fact, later G3 CPU's (like the ones used in the Sonnet upgrades) used
IBM's then-new copper interconnect technology, and use *less* power than the
603's used in the 1400, so battery life was (is) actually boosted by
upgrading to a faster CPU!

There's no such thing as (Mac) OS 9.1.5. Mac OS 9.1 was the (official) end
of the line for the PowerBook 1400 series. But with a little bit of
fiddling, tweaking and hacking, 9.2.2 can run on it, too:
