I forgot to mention that max1zzz (who is a serious Mac mad scientist!) very kindly diagnosed the open traces on my LCIII+ and transferred everything from my board to one of his new production boards. That's how I found out it was rotted traces. I'm unaware of any reversed capacitors on these...

For what it’s worth, my LCIII+ died a few years after being fully recapped. The traces on the RAM address bus had corroded internally, due to electrolytic cap juice pooling there before it was fixed.

Can’t add much beyond what’s been said already, other than the Q605/LC/Performa 475 is a great if not the best budget 68k machine! A good ultrasonic cleaning, recap the logic board, max the RAM and VRAM, and add a ZuluSCSI, and you’re set! My favorite pizza box Mac!

Very cool piece of software! I'll be installing it on my Macs that use ZuluSCSI.

Very cool. I'll stop in next time I have one of my machines setup. They're all stored in the closet at the moment.

For what its worth, the cap kits I've gotten from console5 were great for recapping my LC machines.

All three of the Rack Macs in this thread are awesome! Love how first one kept the beige color scheme and the second recreated the Q605 front bezel. The third is just cool cuz its ex-NASA, and has a key...nice ;)

Hey and welcome! For a first 90s Mac, I'd say either a Quadra 605/LC/Performa 475, if you were wanting to run primarily 68k apps. Otherwise, I agree with what was said above: a Power Macintosh G3. I have a B&W G3 400MHz rev 2, and its a screamer. A 7500 would also be an ok choice, but those have...

My Performa 475 is also in very good condition after all these years. Still works perfectly on all original caps, with no signs of leakage as of yet. I do have new tantalum caps for it though, along with caps for my other LC machines that need them. I plan on tackling it once I grab a hot air...

I threw a 7200rpm SCSI drive in my B&W G3 when I got it out of storage and working again. Mac OS 8.6 boots super quick. I know it’s not 9 or 9.2.2 but it’s super snappy to use.

Any easy fix is a good thing!

Mine turned out to three corroded open traces on the RAM address bus. Probably from the original caps that leaked before I had them replaced. I ended up having max1zzz swap my chips and components over to one of his new reverse engineered purple motherboards. It’s been fine since :)

Agreed. My LC II is completely non functional, yet my older LC still works. LC caps leaked less than the LC II. I’m ordering a hot air rework solder station soon and I already have caps on hand to replace both machines.

Definitely gonna check this out when I fire up one of my old Macs :)

Haven’t had any issues with my board and the PDS ethernet card I use. :)

Max, you’re a mad scientist!

Very nice

Never noticed any of my machines running any slower with older/original caps that needed replacing. And oh yeah, SimCity 2K on an LC or LCII is gonna be painful...lol! Its still pretty damn slow on my LCIII+. I play it on my Performa 475 at minimum, or the B&W G3 if I want the fastest snappy...

Not sure. If it supports using .hda files as hard drive images I’d imagine it would.

I don’t have any experience with mini vMac, so I don’t know if it even supports using .hda files as hard disk images. But you just drag the .hda file in the Finder to the sd to copy it for use in the bluescsi, just like you’d copy any other file to an sd.
