by just swapping in a 25MHz 68030 etc ?

I recently got a IICX DOA from eBay. Recapped the logic board, graphics card, power supply and floppy drive. Cleaned it up, put it all back together and thankfully got a nice boot chime with no issues other than the fact that I'm just getting a blank white screen on the monitor. I noticed when I...

Just found this and curious if anyone has done any troubleshooting with it? https://macintoshgarden.org/apps/applecat-se30

Interesting surprise when I opened this AA15830. It appears that C1, C2, CA, C16 are Red film capacitors with the black rubber insulation around them. Are these considered more reliable than the block shaped ones that crack/explode (rifa's etc)? Also the large capacitors C8 and C9 appear to be...

Thought I'd share this. I made it so I wouldn't have to keep going between pages on the schematic. It's in progress but i believe it's all correct. Please let me know if you find any errors. https://docs.google.com/spreadsheets/d/1RiMi1-8Q4qTq2rb5jEABZ0Hbr0nSUzj3OomMximtY2E/edit?gid=0#gid=0

I'm trying to remove the GLU from a IICX board without damaging it. Currently "practicing" on the NUCHIP which I don't need. Removed as much solder as I could with wick and put plenty of flux on the pins. Then attempted to remove the NUCHIP with hot air using all the technique I'm familiar...

Sorry for this noobie question but what does this mean? It can't be ground, those pins are obviously marked and it can't be to nothing, those pins are left off the schematic so I'm lost on pins going to -x.

I have a reloaded board in a Simasimac status. Current clock signals are: Y1 = 32Mhz in spec Y2 = 32Mhz in spec GLUE PIN 17 = 32Mhz in spec GLUE PIN 18 = 16Mhz in spec Y3 = Erratic, Intermittent supposed to be 16Mhz? Sometimes around 10, sometimes no reading. Anyone have any idea what might be...

Need to find another one the cheapest way possible. Thanks for any help.

(for idiots perhaps...). I've got a Simasimac reloaded SE/30 board and I suspect the GLU chip is at fault. It cleaned up well but was kinda rough when I got it off the bombed board. I have checked all pin continuity several times and everything checks out to destinations. No bridges also...

As I’m working on an SE/30 reloaded board, a few questions have arisen, If anyone would like to offer any knowledge or advice, I’d appreciate it. 1] U32 Crystal Oscillator (see pic) appears to be polarized based on the silkscreen on the board? As I was cleaning the parts, the writing on the top...

By serial number or other? Is it true that these are the most prone to leaking? That has been my own experience.

What would be the best way to test a glue chip from my sadly battery bombed SE/30 to see if: A) the corrosion which has been cleaned off was enough to destroy it. Looks OK visually.. B) I didn't kill it with my heat gun trying to remove it. Thanks for any help. All I have is a multimeter but...

well I took a chance and lost on this one… Thought you should see this mess though.

I've got a USB drive with a 10.4 Tiger image. It works fine as an install for my Power Mac G4 MDD. Trying to format and install tiger on a new SSD in the PowerBook G4 but the USB disc does not show up at all. It doesn't show up in open firmware mode either under "dev / ls" but as stated, it...

Is it supposed to be blowing air up into the computer or down out of the computer?

Wondering what the prospects of finding one of these are , if they exist or if I should bother trying?

Just realized I ordered several 85C rated caps for a Classic power board recap. Is 105C necessary?

Apparently dead (and free). Will post what I find and hopefully the restore here.
