  1. You can use adapters made for PowerBooks up to the Pismo; that's what I've been using for years to power my 1400c. https://www.ebay.com/itm/Apple-Powerbook-G3-Pismo-M7572-Compatible-Laptop-Power-AC-Adapter-Charger-/112650584431 They're still in production and could probably be found cheaper than this, it's just the first one I pulled up.
  2. A 180c RAM card will work just fine in a 170. I ran my 170 using a 10 megabyte card from a 180c for a while before eventually getting a proper 6 megabyte board. The 150 is the only 1xx PowerBook who's RAM can't be used in the 170 (the 150 motherboard is based on the PowerBook Duo and uses Duo RAM as a result). The machine will only address up to 8 megabytes regardless of the card that's installed. But it'll fit and work without a hitch.
  3. Wait, no. Now that I think about it, I'm pretty sure Classic mode needs a minimum of 9.1 to operate (9.2 if running OS X 10.4); 9.0.4 was only supported during beta development of OS X. Hmmm, yeah, I think you might be SOL on this one. I found a link to version 2.7 of the Pismo's firmware: http://web.archive.org/web/20020803165740/http://docs.info.apple.com/article.html?artnum=88042 Does it just error out if you try to install it? I wonder if the installer could be edited in ResEdit to bypass any checks that look for a newer firmware version than what's t
  4. I haven't found any references on downgrading ANY older Mac's firmware from that era. If 9.0.4 is absolutely necessary for compatibility, could you run OS X then just launch the programs that need OS 9.0.4 via Classic mode?
  5. First answer: Unfortunately, no. Replacement batteries were available up until the mid-2010s from what I recall, but they’ve all been discontinued. Second answer: They’re easy enough to rebuild and can be done with either NiCad cells like those it shipped with; or NiMh cells which have a higher capacity (that’s what the later, aftermarket batteries used). If you don’t want to do it yourself, there’s lots of shops that rebuild batteries. There’s no internal logic to these batteries, just a couple thermal fuses, so finding someone to rebuild them shouldn’t be hard.
  6. This is the first I've heard of BlueSCSI, I'm assuming it's pretty good? I've been meaning to replace the mechanical drives in a couple 68K PowerBooks, but the high price of SCSI2SD drives has slowed down that endeavor.
  7. Since it emulates a SCSI2 drive, it should work without a problem. To mount it internally, however, you'd need an adapter for the connector, and I'm not sure if one exists. I've seen doohickies that adapt an external, D-sub SCSI connector to the PowerBook's cabling, but that's about it. Which might be why nobody's really reported trying it, yet. If you need its advanced features like floppy/CD image support; you could mount it in an external enclosure and connect it that way when you need those feature, and use a SCSI2SD internally.
  8. The module from the 180 may or may not fit, depends on what's in there and how lucky you are. The sockets are the same, but the exact fit is different. The "c" variants of the 165 and 180 have an extra cousin card plugged into the motherboard that drapes over the space that would normally be taken up by the larger RAM cards on the black & white 1xx PowerBooks. Rather than the straight-ish, long shape of traditional 1xx RAM, the 165c/180c models have modules that are sort of shaped like stubby C. When inserted, they wrap around the interconnect board's connector.
  9. The shield can be made of any material that's conductive, all it really does in practice is absorb any electromagnetic fields. You could run the PowerBook without it; there's just a moderate chance that it would interfere with a nearby, sensitive piece of equipment. That's why the manual insists on their re-installation, they were necessary to pass FCC certification. But anything else you own would have also passed FCC certification, and should have their own shielding to protect against interference from an external source. If you do want to fashion a replacement, any thin, conductive me
  10. Emmpathy has been hit-and-miss for me when it comes to reconditioning a battery; it'll usually wake it up, but can't clear all the errors. The smart probe aspect is extremely useful for checking the battery specifics, so the program still has an important place in my PowerBook 5xx toolkit. But when it comes to resetting the battery and clearing up any errors, I've always had the most success with Apples Intelligent Battery reconditioning software. I've tried using Lind BU500, and it's never really done anything for me. There's a guide to modifying it so it refreshes the battery con
  11. Publicly available, full schematics for PowerBooks are, to my knowledge, none existent. There's been a few threads in a few places over the years looking for schematics; and I've never seen any bear fruit. The closest we get is the official service manual which only has an exploded view with all the parts at the end, and a developer note Here's a link to that developer note. There's a block diagram of the motherboard, some pin-out info for some of the connectors, etc. I'm not sure exactly what information you're looking for, but maybe it'll help: http://powerbook.micahgar
  12. To my knowledge, there's no way to force it to boot from a floppy, any classic Macintosh will just do so no matter what as long as there's a bootable diskette in the drive. At this point, I'm wondering if there's something wrong with the drive electronics themselves. While there's probably some sort of adapter that would let the drive function externally, there's always that point where the costs outweigh the benefits. Personally, I'd sooner get a SCSI2SD of a newer drive with a higher capacity. The 160/180 in SCSI disk mode idea is definitely the cheapest way to get the driv
  13. Only time I've run into this is when there was a SCSI ID conflict. Since it's an internal laptop drive, I'm not sure if there's any jumpers on it to set the SCSI ID, but that would be a place to start. Not that it should matter, with nothing else plugged in that drive is the only thing on the SCSI tree; there's really nothing to conflict with. Have you tried booting the PowerBook off a floppy disk to see if it'll continue booting? There could be something on the disk that's tripping up the system
  14. Where did you find the screws that you used for this repair? My 180c's lid definitely needs some repairs to the hinge mounts and I don't mind the look of the flush-mount screws at all.
  15. Are you just trying to remove the battery from the laptop, or take the cover off completely? If you’re just trying to get the battery out, the cover is attached to the battery itself. Just slide it forward and pull the battery out from the side of the laptop. If it’s stuck, the battery has likely leaked. The easiest way to remove it at that point is to take the machine apart. If you’re looking to remove the cover from the battery, just keep pushing it forward. With enough force it will slide off the rails keeping it attached to the battery.
