You're quite right Dr OM - that was sloppy of me; the PB100 had a lead-acid battery ( heavy, but rugged; lead-acid batteries will put up with a lot of abuse ) unlike the following PBs.
The battery style to which I referred, is the one that fits the 140, 145, 150, 160, 165, 170, and 180 models. The point I was making, was that one may safely use a battery or power supply capable of providing MORE than an earlier model's native supply provided. That is, one may safely use a PB190 power supply to run a PB140.
Oops, wrong example. The PB190 not only uses a higher power (PB190 - 48W, PB1XX - 15-22W) power supply it is a higher voltage (PB190 - 24V, PB1XX - 7.5V). Since the PB190 uses a different connector you can't plug it in anyway.
PB160c and PB180c require a 7.5V, 3A power supply. Other PB1XXs (not counting the PB100 itself) can use either the 7.5V, 3A power supply or the 7.5V, 2A power supply, the type they shipped with.
Remember, higher power can be okay (not always) but the voltage must match.
While I've never owned a PB100, I've heard enough about them to develop a healthy respect for them; they broke ground in a lot of areas. Thanks for edifying my sloppy contribution :)
>The PB145 will draw about 2.5A at startup, and 1.75-2.0A in normaluse (with backlight on). If you can find ANY good 100-series battery, it will fit the slot, and power the PB145 just fine. Same goes for 100-series Power supplies.
Does 1xx include the PowerBook 100? The power supplies may be exchangeable, but AFAIK the lead-acid PB 100 battery was one-of-a-kind, not even swappable with the Portable's lead-acid. The 140 and 170 had NiCd batts as well as the 145 that replaced the 140. The 190/c/cs was the first to use NiMH batts, the same as the 5300.
Cheers, OM
Generally the term PB1XX does NOT include the PB100. The PB100 was different in so many ways from other PB1XX models that it's safest to assume it is not included in discussions of PB1XXs unless otherwise indicated.
