Hi, I'm Fabrice. New here, but not to Macs. Since 1987 I've migrated from a Mac_SE to Mac_SE30 (with Xceed color monitor card), to PowerMac 7600, some SuperMacs that were my mother's, several iMac originals, 2 PowerBook Wallstreet G3s, a Quadra 605, a PowerBook G4, my son's PowerMac G4 + accelerators, daughter's iMac G5, etc. Still have (or have again) most of them.
Also an MBP1,1 15" (2006;works fine), an MBP2010 in daily use (has fixed GPU cap); my main machine is a mid-2015 MBP-r 15". The MBPs are max'd for memory and two have replaced, upsized SSDs. Between max memory and the SSDs, they're perfectly speedy. (I'm not a gamer!!
)
Most of the older ones are probably suffering defunct power supply caps and dead internal PRAM or std battery packs. I have the SMT rework tools, but in many cases, way too much surgery to get to the raw component — and then you have to source the replacements. So most of those will probably go in the trash. Anyone know of an effective way to recycle?
My main goal is to make one perfectly functioning Wallstreet out of the two, because of their tremendous flexibility. Have a SCSI 30-pin adaptor (for an AGFA scanner, will probably toss the 3.5" SCSI HDs), a dual USB PC card, a Buffalo AirStation 2.4 & 5.2 GHz wifi (no driver), a pluggable ZIP drive, 2 pluggable CD drives, an Excaret Pro HD pluggable, and probably lots I've forgotten. And lots of 2.5" HDs.
So that brings me here today, looking for a PBG3 PROM battery and a usable internal battery. So far those companies that list them do so as teasers - they don't have them. Still will try eBay. I might try to construct one or two from cells with welded tabs, but need to know voltages. BTW, most electronics are highly tolerant of +/1 1v. difference from nominal. Still want to know voltages.
So, what say all of you? Ideas?
