Check the specs on your MacBook to confirm if it is a 32-bit CPU and 32-bit EFI. Most distros are now 64-bit in both which won’t work on 32-bit architecture. In the link that @phungus provided, I was dealing with a 64-bit CPU and 32-bit EFI which makes the installation trickier. If you are...

Update. The triple LR44 setup didn’t last very long for me, with one of the cells going flat in less than a year and thus not retaining enough voltage to preserve the settings. A little over a year ago I opted to try a 3.6-V AA-sized ER14505 I purchased from Mouser for a little over $8 - I know...

I have a Macintosh IIvx on its way, which I intend on restoring.

I’m comparing your board versus mine in the IIsi restoration I wrote about here. I see you have the ROM SIMM instead of the onboard ROM, and you had the same trouble areas at UA5, UA6, and UE5 that I had due to corrosion from cap goo. My suggestion is to double-check your work at UE5 and make...

I figured out my problem with curl throwing an error message. It's a firewall configuration issue at my end.

For what it is worth, I don't see a similar destruction problem with Linux Mint 22. Also, thanks for the link to the rEFInd version of the ext4_x64.efi driver. I am finding that the problems I had with the driver sourced from the original location have gone away and I'm having no issues with...

Color Classic update: I removed the Booster 30-L33F clone board and the CC passed all tests, including the SCSI test it failed with the board installed. Now, I just need to figure out the problem with my SE/30s. Thanks for the earlier responses, y'all have given me a few items to run to ground.

It doesn't matter whether I am using a BMOW Rominator II or a stock ROM SIMM, I get the same failure. Puzzling.

I have a recreation of a TechStep, so it has all the ROMs in it. I wanted to rule out all else before concluding that the ROMs in the TechStep are somehow at fault. A little more troubleshooting with the IIci. I decided to remove all cards and disconnect the BlueSCSI to see if the IIci would...

Recently I obtained a recreated TechStep for testing the variety of compatible vintage Macs in my collection. All of the Macs are functional, and I was curious about what the TechStep would say about each. Here is a summary of my experiences and results, in case anyone else finds the...

Try Method B first to see if it works for you. This is a side-by-side comparison of the before on the left and after on the right of the config.plist file, showing replacement of the BlessOverride parameter with the Ubuntu bootloader information, assuming use of GRUB as the bootloader.

Hey Garrett, I’m thinking through the restorations I did to a pair of IIsi PSUs to see if anything I did might be of help. For the worst of the two, I replaced a diode and resistor on the secondary side that were cooked/eaten by cap goo. I tested the rectifier connected to the heat sink to...

As a test, have you tried measuring the resistance directly on the pads beneath the 4-pin connector? It has been a while since I installed Spicy O’clocks in my Mystic Color Classic and Quadra 650 but I don’t recall seeing anything unusual in the resistances. I imagine you are using Kay Kobe’s...

I recently completed a recap of an ASTEC power supply unit in my SE/30 and I thought I would share the particulars, in case any of you fellow tinkerers decide to do the same. The reason I chose to recap is because I noticed the 5V line was running slightly low - around 4.85V - and tended to...

I’ve encountered the speaker pop and no boot if the RAM is not seated properly. Probably worth a double-check and possible cleaning of the slots and RAM sticks. Also, I second the suggestion to check the power on circuit. I wrote about my IIci power on circuit experiences here...
