The year is 1991, it was either a car or Macintosh PowerBook, so here’s me taking the metro with the latter.

(Haha, new #MARCHintosh acquisition! PowerBook 145B, with an internement display, TBD, but it was $50, very pristine and en canadien français).

My first 68k PowerBook!

EDIT: It has found a home.
#Free to a good home: An Apple PowerBook Duo AC adaptor, model no AA19200, Apple model no M2693 with battery charger that clips to the side, model no M1812 with matching grounded power cord. There is a small crack in the case next to where the lower cord hook folds out. :apple_inc:

#Free to a good home: A PowerBook Duo 2300. There's an issue with a strip of the screen, which went away a few minutes after booting. I don't remember it having that issue back when I stopped using it. 🤔 Includes an AC adaptor and PowerBook grey grounded power cable. The modem cover has snapped off and a piece of duct tape has been applied to keep the dust out. :apple_inc:

@riley @shyra uhm did #apple manufacture disks with a custom firmware? That would be very typical...
BTW, #bluescsi is reported as fully compatible with my #powerbook 170, so I'd expect it to Just Work™...

New model: #PowerBook 5xx HDD caddy, with both an HDD and a #BlueSCSI variant.

Might still need some tweaks (not yet sure for screw hole diameter)

It's week end, so again on the #powerbook 170.
I removed the cmos battery to avoid future leaks, and made the trackball finally work replacing a capacitor and cleaning/re-setting all the connectors.
Now on the #bluescsi. No way to make this thing to boot from it. I tried formatting the virtual disk from the 170 instead of creating from the pc. It formats but then while copying the files I have a lot of i/o errors. It seems like it bursts for some seconds and then hangs. The OS seems waiting a bit and then showing the error, maybe after a #scsi timeout...
Not sure how to troubleshoot this. The bluescsi log in the microSD doesn't show any error...

Thinking about upgrading my powerbook 2011 to something a bit newer but not brand new. I’m looking for something that can run the latest Mac OS though ideally just under whatever the cutoff was for that apple AI shit. anyone got a recommendations? #applehowtos #powerbook #macbook


Again on the #powerbook 170: i'm trying to understand how the heck should I set the #bluescsi #termination #jumpers. The website dehij.hiddej.nl/ is offline. I could find it on the #waybackmachine , but it doesn't load...
BTW, I found a schematic on github.com/dehij/powerbook-blu… . That's the v2 schematic, but it seems very similar to the v1.1a I've got (they changed only some footprints, I believe). I see I can, using the jumpers, set the #SCSI #SCSI_IO pin to 5v, to ground or to #TERM_PWR (that's another SCSI pin). I unerstand I should terminate the bus, as there's no other devices connected, but I really have no clue on how I should set those jumpers....


#retrocomputing question: I'm trying to boot my #macintosh #powerbook 170 from #floppy . So i used a #linux machine with #dd to write a known good #system7 disk image onto a known good #floppydisk .
But dd exits reporting an i/o error while writing. Note that I can create working #msdos floppy with the same drive and same floppy. Also tried other floppies, same error and every time at the same place (44kb from the start).
As expected, the mac won't boot, but for a little while I see the happy mac icon, so it seems the first part of the disk is correct.
Is there any mac-specific parameter to pass to dd? Any other hints?


So, a PowerBook 190cs fell into my lap today (no, that wasn’t the cause of the damage) and needless to say, I couldn’t say no. I mean, what if it had already been upgraded to a 5300cs, or its hard drive contained rare unarchived software on it? Perhaps its destiny is to become an awe inspiring frankenMac. Thankfully, at the very least, parts.
