I totally get that. I'm not familiar with any other adapter solution except for the VGA adapter A2Heaven used to make... I'm not sure when or if they'll be shipping that again, but it looks like it works really well...
@dosdude1 recently set up a dial-up ISP (https://dialin.doslabelectronics.com/), which is super cool. I decided to try connecting using my PB180's (running 7.1) internal Global Village modem - I can dial in and connect via PPP (sweet sweet music) but I can't load any websites. So I'm thinking I...
Welcome! The IIci is a lovely machine, great to see another one getting the attention it deserves. :)
F1 is a fuse, schematics say SMD200-2 (so, 15V, 2A):
Q3 is a transistor - the Bomarcs show the transistor symbol and the '3', but not 'Q3'... then uses its own internal reference (1A) that it...
I feel ya... welcome to hobby. :) We're dealing with really old devices that often have (ike this adapter) suffered damage, so it's not always going to go smoothly, and may not ever result in a fully functional device. Just about everyone in this hobby has several machines that just aren't...
I've recapped a couple 1.44 drives in a shotgun attempt to solve issues (which it didn't), but it did seem like the caps needed to be replaced - a bit of leakage, especially the two by the motor. Considering though these caps are so inexpensive and easy to replace, why not do it?
Even from the Australian sites? Hm. Well, I don't know much about Jaycar or Altronics, but they each seem to have several locations in Perth, worth a call.
There's a cap list for the 5140 in the first post of this thread: https://tinkerdifferent.com/threads/recapping-powerbook-100-series-7-5v-2a-ac-adapter.28/
That post links to suitable replacements at Mouser, so make note of the physical sizing as well when ordering from your vendor of choice...
Here are a couple schematics, which might help trace the issue... at least back to pin 25 of the CX-23077A or pin 9 of of the floppy connector -- depending on the drive you have there (as @max1zzz suggests, you might be getting an eject signal on that pin from the Plus instead of it being...
Welcome to the addiction! 😄
Personally, if the machine is working, I see no reason to fuss with having the owner open it up... I mean, is anything that could be in there potentially be a deal-breaker?
True true. The 140 schematic on bitsavers doesn't seem to include anything beyond than the mother and daughter boards (will look closer)... Still, should be doable (says me, the guy who is knows just enough to be dangerous).
Hot damn! Thanks for posting on this. Inspiring me to try this on a different 1xx PB (my 170 and 180 both have dim ccfl's)
Also - thanks for posting to schematic... didn't realize it was available!
