Announcing a new HyperCard Project: MacRefLib (Macintosh Reference Library), a MacTracker-esque application that I will be developing with data (and permission!) from apple-history.com. It will encompass everything from the 128k to the PMG5, and then some... Some preview shots: Uploaded...

I have figured out the root cause of all my Plus problems as of late: The voltage regulator pot was WAYYYYY off! Testing revealed that the +12v rail was only putting out 10.5v!!!. No wonder I had a wavy picture - it's a miracle the Plus ran at all! Anyways, thanks to all those who helped out...

After a few searches, I figured out that the FDD may be the problem. Unplug it, plug back in everything else, flip the switch... BEWM! Welcome to Macintosh So how do I fix my FDD's troubles? On boot the inner head would repeatedly engage and disengage (clicking noise). Or is this perhaps the...

The problem! It's come back! Has anyone experienced this "infinite reset" problem before?

I'm happy to report some good news: Uploaded with ImageShack.us Just needed to reflow the solder on all power/sweep connectors.

I go to turn on my Plus today, and I get to hear this: chirp, chirp, chirp, chirp, chirp, chirp, chirp, chirp, chirp, chirp, ... No display, no bong, and sometimes the FDD starts checking the drive ad infinutum. Turn it off, bring it to my workshop, open 'er up, check the cables, everything...

And the flyback! What happens when you attempt a different resolution?

Skynet? :lol:

I heard somewhere that the 166mhz 603e in the 1400/166 is actually a 180mhz or so module. Is this true? I wouldn't mind unlocking 20mhz for the cost of an oscillator.

I have one of those 6400's myself. Nice Mac, arguably better than the 6500. Mb will probably be fine after giving it a good cleaning to get rid of the battery deposits. A dishwasher run may be a good idea too. The FDD in my 6400 is a bit worn too - it struggles to eject disks. I'm thinking...

Cut resistor R8 and put in four 1MB modules from my long-gone IIcx.

Getting an adrenaline high from discharging a 20 year old 9" CRT. xx( In related news, I have completely repaired the Plus. It turns on and has successfully booted several times from a SCSI hard drive. :approve:

One technical question: Once disconnected, is the Anode wire and it's flyback transformer still dangerous to touch? Should I discharge it again (power/sweep board has been sitting for a few days now)?

Sorry 'bout that. My first instinct is to do a Google search, which was fruitless. Anyways, I'll take a look and get started. Watch here for updates.

Can any Plus experts help me out with this?

Sure the CD drive is properly terminated? That can cause a lot of issues at boot time.

And where will I find that?

OK, here they are: Logic Board: Power/Sweep Board:

This is very odd.... I'll try reuploading them.

Did you miss the large corrosion stain on the power board in the last three pics?
