We just uploaded our YouTube video on the LCD conversion kit HERE!

Hey everybody! Keith and I just published our first edited video on the Macintosh Color Classic LCD Conversion Kit! Check it out HERE: Please like, share and subscribe!

Once upon a time, there was a used Macintosh place called the Calgary Computer Exchange. In the early 90s, they had TONS of used Macs that were leased, and then became available for sale to the public once the lease was over. I found a Macintosh IIx there, and was very happy with it. I also...

Revisiting this thread: I have two Mystics with PowerPC boards that will NOT boot to PowerPC mode. I get the PowerPC chime, then a black screen and nothing. I haven’t measured 5v, but I’ve been told that the 5v and 12v rails might be heavily taxed by the 601 CPU. They boot into 68040 mode...

Hello there. I have a 5126 Backlit portable, but the backlight flickers with any hard disk or floppy activity. Might that be an inverter board issue, if I already had the backlight board recapped?

Makes sense. I’ll take a look at that then.

Hey all. I’m about ready to rip my hair out and I need some explanations. 1. Color Classic with 575 board 2. 640X480 Analog Board VGA Mod 3. Fresh install of 7.5 from Factory Apple 575 CD-Rom drive. 4. Installed on Zip drive as well as hard drive for testing 5. Daystar PowerPro Control...

Thanks for the info. Unfortunately, my MacEffects ram card is no longer lighting up. I would really like this machine to work again. Who here can diagnose my MacEffects ram card?? HELP!!!!

Hey! I don’t know why I didn’t see this thread before. I have the EXACT SAME PROBLEM. I’m using BlueSCSI V2, 8Mb MacEffects card, the backlight freaks out with 7.5.5 all the time, restart in 7.0.1, backlight is fine. Then try running an older version of Photoshop, boom! Backlight starts...

Hi there, I am keeping both of them, as I got the 2nd one repaired by purchasing a series of replacement 040 sockets. Thankfully it's back in business. The reason the one was booting to black was because I was using the wrong extension. I have two Color Classic Mystic PPCs, and I may sell...

How are you running the Carrera without the Wish I Were extension? I finally got my Carrera to work today after months of fighting with it. Do you have a useful custom ROM that takes care of that or something?

WONDERFUL WORK GENTLEMEN. This is crazy cool.

This thread is fascinating. Didn't realize it got updated in 2024. I have the NewerTech 603e 183 MHz card, and am interested in what's going on here.

Just bumping this thread, what’s the story with PowerPump?

This is insane. I’d love to have a IIsi in an SE/30!!!

I have the Apple version of this Ethernet card, and I'm also very curious about this. Many people say that they won't work together, but is that because of the 24/32 bit conundrum? We all know that the Apple IIe card "says" it needs 24 bit addressing turned on in order to function, but then...

Following up on this: I have two of these cards, one has bent/broken pins on the 040, and the other one gives me no video when switching from 040 to 601 boot. Will always show desktop when booting to 040.

Apparently, if you hold down the mouse button while booting, it will bypass the ram expansion and just show you what’s on the logic board directly. I’ll try that and see what happens.

The photo I sent with all the chips, you can see the JP1, my cleanup job wasn’t perfect, but it says 2048 now so I’m happy about it. When I was inserting the ram chips, I got a sad mac code. After removing the board I noticed that some of the chips legs were outside their sockets!! I fixed...

Yes, that photo showed what it looked like before I removed it. I think you’re right about the 512k on the logic board. Hard to find an original 128 I guess as most users seemed to upgrade theirs.
