    PB180 preventative maintenance?

    Purchase the "VCN" variety with vertical mount tabs that will allow you to solder the wires on further away from the cell.

    PB180 preventative maintenance?

    Whoops, that PRAM batt is the one I built for my Duo. PB just solders in :)

    PB180 preventative maintenance?

    I believe you've covered the major bullet points. I'd also consider a SCSI2SD, as even a working original is a likely failure point. The vast amount a storage is nice too! A suitable PRAM replacement can be fashioned from a pair of VL-2330s and a bit of heat-shrink. In addition to the much...

    Duo Li-ion Battery

    Alright, I promised an update... The ideal diodes arrived and they work nicely! Under full load, I'm only seeing a ~.2v drop, but (because of course there's a but) I'm still getting low-power alerts from the OS throughout much of the discharge cycle. The OE pack contains 10 NiMH cells in...

    Powerbook 160 LCD woes

    This is the behavior that drives me bonkers. People don't check completed listings before posting to see what actual market value is. They see one example of what they're selling listed for an absurd price (that's been sitting there forever unsold) and immediately assume they too own a goldmine.

    Using SCSI2SD v5.5 in a Powerbook

    Sure, but per the attached picture, the connector is already different than the one included on the v5.5 (not 90deg). I'm just suggesting that if a different part is being used, a DB25F is more suitable for a device targeted at PowerBooks or other mobiles since most either a) have an HDI-30, b)...

    PB 1[4-8][0,5]c? Li-ion Battery

    With all of last week's posting issues resolved, let me try this again... Not sure if this is most appropriately posted in this forum or over in Hacks, but I think it's more likely to reach the target audience here :)  As a follow up to my recent Duo Li-Ion battery project, I've been working...

    Using SCSI2SD v5.5 in a Powerbook

    Very nice! Good to know about Artmix's shenanigans. Long time OSS / GPL proponent, so they'll get none of my business. Only thing I like about their unit, however, is the included metal frame with horizontal threaded holes so no 3D printed or other custom mount is necessary. Also, I'm probably...

    Using SCSI2SD v5.5 in a Powerbook

    Thanks for the update (I was just about to pull the trigger on an ARTMix) and sorry for piling on. Happy to keep waiting knowing something is in the works.

    Basket Case PowerBook 180c

    It's buttoned up at the moment, but I'll be opening it up in coming days to 1) send 5v (probably from the ADB since it's right there and fused) into pin-5 of the SCSI HID-30 connector for term power and b) to yank the Global Village modem and install a ribbon cable in its place so I can start...

    PowerBook 1xx Wireless Modem

    It'd be interesting to try. To get that actually working, I've wondered if I'd need to implement some of the modem-specific functions like DCD, Modem.Busy, etc. that I'd planned to omit. Not sure what the driver expects... Yeah, my initial mockup had and SMA connector there, but I decided on...

    Goofy Line on PowerBook 180c Display

    There I can certainly help you! I just re-capped mine a month ago while I was in there fixing the cable and Mouser conveniently stores your order history :) I ordered the following: 4 x 47uf, 16v, p/n: UUL1C470MCL1GS 2 x 10uf, 25v, p/n: UUL1E100MCL1GS 3 x 10uf, 16v, p/n...

    PowerBook 1xx Wireless Modem

    The components I've ordered are still arriving, but in the meantime I spent some time getting the board layout closer to actual. Upon further review of the "Modem card electrical interface" section of the Deverlopers Note, it became obvious that I'd need to convert logic levels down and up (Vih...

    Goofy Line on PowerBook 180c Display

    Fixed lines would likely indicate a failed panel, not a cable problem. The cable doesn't have conductors that drive each scanline, but rather h/vsync and a few data / clock signals for each color R, G, and B. @ian1035nr What you've pictured is called cross-talk, and while that's expected...

    PB Duo schematics?

    Let us know what you find! I would have loved to have the schematic when fixing the BSOD (blank screen of death) issue on my 280c. Maybe you'll turn up something that reveals more about the express modem board too. They really decreased the detail level there between the PB 1xx Developer Notes...

    PowerBook 180c That’s Picky with RAM

    The connectors in that platform can be pretty finicky. I think it's a confluence of age-related factors. Surface oxidation on the contacts, diminished mechanical tension within the female connectors against the male pins. etc... I recently posted about a similar problem affecting the ribbon...

    PowerBook 1xx Wireless Modem

    The little Vonets VM-300 wireless bridge module I assembled for use with my Duo last week didn't really scratch the itch I have for a fully integrated, wireless networking solution, so... in my on-going quest for a portable and connected 68K, I've fixed my sights on the Global Village modem in...

    Using SCSI2SD v5.5 in a Powerbook

    Unobtanium indeed. Been looking for one for my PB 180c :/ Wish I knew if/when they'd be available again and whether on not to keep waiting or get creative like you have. My inquiries to @inertialcomputing have thus far gone unanswered. What are the overall dims of your arrangement?
