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…

I haven't specifically killed a Pismo, I killed a Classic 2 and PB 150, by rushing, which you and I alike have done. I know nothing about Pismo's save for that they are nice powern…

Tried the PRAM reset again, no dice. I suppose the disk drive could be bad, but its not even hitting once. It's like the system is just sitting there waiting for something.

Make sure you get at least to the third chime when resetting the PRAM. Not everything is reset only on the second chime. We also can't rule out a bad floppy drive. Do you have a…

BTW what does the jumper at J103 and J106 do (towards the front center of the board)? There's no Jumper on 103 but there is on 106. Tempest

I've heard that you can use two normal terminators in a row and it acts similar to a black terminator on the IIfx. I don't have a citation for this though.

I was under the impression that the IIfx had NO electrolytics on the logic board. I could be wrong, but that's what I seem to remember. I know for sure that the Quadra 700 doesn'…

Thanks, Mars. (What a great club.) Any advice re how much gets borked? Motherboard and processor card only, or more than that?

Welcome to the club...

Well, I seem to have had a triple-biorhythm low kind of day on Saturday - either that or I was just stupid! Managed to lose my glasses AND fry one of my Pismos, all within two hour…
