- I've read the portables need a battery because the power supply isn't enough to operate properly. You need to leave the battery in the Portable. - Did you look in the Control pa…

Sounds like bad caps to me based on what the other guys are saying in the other threads the past few weeks. I'm sure one of them more in the know will have some idea more than me …

Have you tried external speakers?

Hey all, I'm new here. I just picked up an SE/30 on eBay for a decent price (always wanted one of these to add to my collection). It works great except when you boot it from a col…

I take it from the context here that the motherboard stays powered alive if a battery is left in a Pismo eh? That sucks... been there too. I fried my only IIGS motherboard back …

That certainly would make some sense electrically if all that is different is a higher ohm rating of the total termination value. Might have to try that at some point when I have …

While the mini isn't as visually robust as a PowerMac G5, I have a hard time thinking of ways in which it is actually less capable at anything. Click to expand... GPU power is …

Yeah I tried that, it still doesn't work. I'm starting to think the floppy has died. I do have a spare Superdisk drive that got out of a dead Classic that I can try. IIRC it did…

id put a multimeter on it and at least see if its putting out 12v and 5v on the drive power lines, regardless on how much power your drawing from it, your not going to get very far…

No clue, but I did unplug the monitor from the second plug on the power supply just in case it was drawing too much power.

have any clue what voltages the power supply is putting out

I did. No dice.

Try a different cable as well as a different floppy drive.

Yeah I tried that, it still doesn't work. I'm starting to think the floppy has died. I do have a spare Superdisk drive that got out of a dead Classic that I can try. IIRC it did…

On top of making noises, the floppy drive should should eject any disk that it can't boot from. So, just the fact that it's getting to a blinking "?" and NOT booting or ejecting th…

It all happens fairly fast and it never tried to go to the disk drive (HD is still unplugged). Shouldn't it at least take a little time to do the memory check? Click to expand.…

Can you tell, is the question mark blinking on the disk? Disk drive troubleshooting: When the Mac is first powered on, there should be a chirp from the stepper motor that moves t…

I got my dual 2.5 LCU G5 for $20 (well, more like $40 after the repairs were made to the LCU) as a replacement to my trusty old 9600 and I love it. lots-o-ram, lots-o-disk space, …

Ok interesting little development. On a whim I put all the memory back in and plugged the IIgs monitor into the card. The monitor isn't perfect, but I can sort of see what's goin…

Try installing only 4 matching RAM SIMMs in RAM Bank A, leaving Bank B empty. Then try the other set of 4 matching RAM SIMMs in Bank A, again leaving Bank B empty. If it still do…

That's an interesting notion, but I kind doubt its application in the "real world," but I've been wrong before. If you want to address more RAM in the SE, watch eBay for one of the…

I took out all the memory and I still get the chime, but no keyboard click or light flash. There are two different brands of memory stick in the machine. Four of each NEC 42100…

This tech note: http://developer.apple.com/legacy/mac/library/technotes/hw/hw_13.html states that: "The Macintosh Portable contains 256K of processor ROM, which is fundamentally…

Already tried resetting the PRAM (got the second Chime) and reseating all the RAM and the ROM. Nothing. I have a disk in the drive, that's what I'm trying to boot from, but it ne…

My guess is that it's not even getting to the point in the boot sequece where it tries to read from a floppy. Video would defintely help here. It seems to be past the ADB check sin…
