I’ll have to look at that Aaron BeOs extension again. The comment in extension manager described it as appearance extension for Copland. Makes sense given the startup screen. I don’t see anything called Aaron BeOs on Macintosh Garden. I do see Aaron be seems not same. Updates: ~Aaron’s BeBox is...

I looked at the disk further. I found the boot screen as a Photoshop image file in the System Folder. The machine also has an extension called Aaron BeOs that according to description on the extension changes the OS appearance to match the future look and feel of Copland. The extension had a...

What are my options for replacing the Active Matrix panel in my non-backlight display? Are there any options other than using a display from a similar Mac portable? I have a PowerBook 170 display which I know is backlite with different connector.

I didn’t boot it into Copland. This was the MacOS install. I looked around briefly and didn’t notice anything unusual as compared to 8.0. I did not see the Copland folder although I didn’t know to look for it at the time. I’ll plug it in again and take a closer look. I think it may be a custom...

Anyone ever seen this version of MacOS? I was testing some SCSI drives and one booted to Copland System 7.5 Pro. The About this Mac shows 8.0.

I need schematics or matrix's I have seen used by many of you to troubleshoot broken traces. I have a IIci that gives sad Mac, portable with non-working SCSI and SE30 crashes on making sound. Any info to help troubleshoot these issues is appreciated Roger

Thx for the info @Yoda . I’ll tackle the display shortly. Update: The vertical lines in the display cleared up after the ultrasonic clean.. Only issue with display is the physical damage. Boots from external Floppy fine. Internal did not work with original drive but have not service it yet...

Update on my progress and couple more questions. After fixing 3 traces, 1 missing pad and recap, it lives again, but has display issues. See vertical bars in the Display. Clearly the display needs replace but are the bars in the display because of the board or the display itself? I do not have...

Well, there ya go, 4.9 ohms. Much appreciated.

This is photo from Mac Portable non-backlight. Trying to recap and repair the traces. I noticed the 2 tinned traces coming from R22 show continuity across R22 resister. Should they show continuity? What is likely causing that if not?

Thx @Sideburn . I’ve seen the remade batteries. I used a lithium ion 6.5 volt battery to test with. I also have a bench power supply but did not use this time. I will probably pickup a battery once I get the board running. I think I was successful at powering the board. It just didn’t want to...

Thx for all that info. Really appreciate the knowledge you and others share. True, my lead acid battery’s are dead. I have the main board removed and sitting on my bench. I connected 6.5v power to the board and tried to get it to power on my touching pins on the IO connector. It would not...

@Androda I recently acquired a Mac Portable, non-backlight. I don’t know much about troubleshooting the portable or its common issues. Mine does not seem to do anything but has not been recapped yet. I see one Axial cap that seems to have leaked. The board looks clean otherwise. About to recap...
