Can you determine why this screen is doing this? All caps have been replaced on back of the screen and on inverter board.  There has been no improvement or change since cap replacement. I've reseated the video cable several times on both ends without much effect. The top portion is always good...

I have a PB 540c with an active-matrix color display.  Everything works but the screen is dark.  The brightness buttons slightly make the brightness flicker when pressed but does not make the screen bright. I've read that I should replace the caps on the screen, which I've done on my PB 180 -...

I want to force my Mac Plus to boot from a certain SCSI ID, where I have a chain that has multiple drives that contain system folders.   I can't change the SCSI IDs of the drives due to other circumstances, so I want to force the Mac Plus to boot from a certain ID.  As it is now, the Mac keeps...

I cannot get my powerbook 540c (OS 7.5.5) to boot from a specific SCSI ID even when trying to manually select at boot (Command-Option-Shift-Delete-#).   I have two different system drives on the same scsi chain, but it will always boot from the drive with the higher SCSI ID. If I manually...

I recently purchased a V5.0b SCSI2SD from Inertial Computing to be used in my Mac Plus.  I cannot get the board to be recognized by a Win8 desktop.  I've tried different USB ports on my computer, and different USB cables... The utility is always "Searching for device". Windows does not...

I won an Apple II "Plus" on a goodwill auction recently for around ~85 total.  I don't typically collect these machines, and the last time i used one i think i was in middle school. It came with a stack of cards that i'm looking to identify.  In the 3rd picture i can see one of them is a 16kb...

This is part of an auction I'm bidding on, but there is no info included in the auction, just this card in the picture:

I've seen online in a few places that it might be possible to upgrade a MP2000 to a MP2100 though a 4mb ram upgrade.  Is this possible and if so can you point me to any information about it?  I'm assuming this does not include just replacing the mainboard because that would obviously be useless...

I bought a PB180 on ebay that had this card, this is my first PB.  I think its a ram expansion card, it has 20 chips counting both sides - i'm hoping it's the 10mb version. Couldn't find this on google anywhere: Simple Technologies STA-PB180 thanks for helping identify!

Do any of you have experience replacing the yoke cable?  I bought a board for 5$ from a garage sale with the yoke already cut.  I'm trying to source a replacement:
