I have 2 PowerBooks with these 2 problems. The 1400c is much better: G3 card, full RAM and more. The 1400cs has an annoying continuous tone that can only be turned off with the volume control. My question is: Can I attach the cs top part to the c bottom part or are there problems with the...

My PowerBook 170 has a weird floppy problem: the PB can boot with any fitting floppy disk - even with system 6.0.8 disk from Macintosh garden.  When I boot with it's hard disk and then put in a known good disk, Finder does not recognize, that there is a floppy disk: no sound, no floppy disk on...

Hi, AppleShare IP 5 and 6 are not allowed to be installed on PowerBooks (PPC 603, -e, -ev). Is there a known way to fool the installer? Thanks. 

I'm using Macs since 1992 (SE/30) but never got this strange alert when copying a RamDoubler 9 image from different CF cards to a harddisk or inserting the original RamDoubler Disk  2: "A disk has been remove that is currently in use. Please put it back!!! Failure to do so may result in loss of...

My Rev. B card cage (Apple M2864 V1/B) was working, when I got it some years ago with a PowerBook 520c. But only for a short time, so I thought it became defective.  Yesterday I've read these posts: https://www.mail-archive.com/powerbooks@mail.maclaunch.com/msg07749.html    and it made me...

Hi there, I own 3 PowerBook 540c and I'm very happy with them. One has a SCSI2CF and another has a SCSI2SD built in, everything works but all 3 have a little problem: after a few minutes without power supply, my PRAM settings disappear. Date & time and energy store are deleted. Date &amp...

Next problem with a PowerBook 5300ce.  I bought this PB 5 years ago but it had a leaking battery and did not boot. On the right side of the power supply board the connectors for the main battery were light blue, corroded and broke when I tried to clean them.  I cut off the leaking battery and...

A 1400cs worries me when testing my PowerBooks: When it is booting it screams terribly until the first extensions are loaded. Then it is silent. I sometimes also hear this sound from the speaker during operation. Can someone give me a hint, why?

I got this card with a SE/30 and can't find it with Google, maybe it's a french card: 1990 memory plus  PN X10-S08 Modam se030 adaptor AMP 535022-1 9145 Yes it's called modam not modem. ;)

Hi, I got this Farallon EtherMac MicroSCSI Adapter (PN574-C), but it seems I can't get it to work - tried it with PowerBook 180c and SE/30.  I'm using the last driver (1.1.2) but didn't find any pdf manual on the wayback machine. Only view informations...

Hi,  I got a dead SE/30: no boing but short rustle from the speaker, black screen, no sound from floppy, SCSI2SD board blinks once, when the Mac is switched on. That's all.  I've read "The dead Mac scrolls" and more and these books told me about a bad analog board when getting a black screen...

Hi, I got a very pretty PB Duo 270c today.  Everything works fine and so I started to check and format its hard disk using a SCSI-connection with my PowerBook 540c.  Hard disk seemed ok and so I started copying install files and more from 540c to Duo 270c.  Suddly I noticed brown smoke from...

Hi, I have to swap the analog board of my SE/30, so my question is: should I also exchange the (working) flyback on this "new" analog board or should I wait, if it'll be necessary. I'm asking, because I have a new built flyback from Artmix waiting in my cabinet. 

Hi, it seems, that my SE's hard drive data cable (of a working hard drive) was broken after several disassembling actions. It's spinning up, but the SE is showing a blinking floppy disk now. The SE still works with an external disk or ZIP drive.  As a SCSI2SD adapter is on its way, I want to...

I found this today and I think it could be useful for SE/30 newbies too.  :) https://www.ebay.co.uk/itm/Outstanding-1989-Apple-Macintosh-Mac-se-30-MAX-RAM-SCSI2SD-8gb-more-/302629103049?_mwBanner=1#vi__app-cvip-panel

Hi, I know hard disks can be formatted HFS+ non-journaled in Mac OS X 10.4 Tiger. But what is the latest version of OS X which can do this? I need it to get read AND WRITE access on a Linux system. see...

This is a great PDF to identify 68k hardware: http://bitsavers.trailing-edge.com/pdf/apple/service/PN_072-8124_Apple_Service_Module_Identification_Manual-Jun_1994.pdf

Hi, I've got a problem with my PB 540c with PCMCIA module Rev. B: Someday the module did not recognize any HFS nor HFS+ CF card anymore. It always wanted to format it as "ProDOS" CF card. When I use my second PCMCIA module (Rev. C) the CF cards are recognized on the same PowerBook without...

Hi, did anybody try this before? Only connecting the Interconnect Board. I would quickly get a working PowerBook. :)

Could anybody make available a picture of the "logic board take-apart tool", which is mentioned in PowerBook 1xx service sources (with a drawing)? Maybe I can create such an alien when modifying a big clothespin?
