Hi, thanks for replying!  I actually did follow that guide. The problem seems the floppy images I have, at least that’s what I’ve been told.  If I use the 2GB 7.5.5 image on that site, it boots up fine. The problem is when I want to install from scratch using floppy images as described above. ...

Hi all, I’ve recently purchased one of these, a v5.1, to use with an LC III.  I am using a 16GB card, and with the utility setup 4 x 2GB drives (stupidly thinking I was setting up partitions and not drives...).  Anywho, I am using a Floppy Emu device and the thing is I boot a disk tools image...

For which of the two..?  ;D

Hi all, Looking for help to try to get a working classic from what I have.  Some time ago I acquired two classics. One I was told did nothing on power-on, and the other while the owner had listed it as working, when he went to test it before actually selling it to me it shiwed a checkerboard...

 Great… I just did another cleaning of it just in case, and nothing same thing… I guess maybe something’s fucked up on it or a trace or whatever because power gets to the port but something is definitely missing because the disks sit there an idle

Ah ok great, so this one...

 Sweet! That document provides a lot of information on the subject, thanks. The only thing it doesn’t say is what the chip’s numbering is or what it looks like so I can find it on the motherboard  :P in any case, unless I can find something wrong with the traces to it or whatever, I doubt it...

Not at home now to show you but yes, checked bot the inside of the connector as well as the rear of the PCB and all looks good. Also, te cable cannot be the issue as the three different devices tested were tested with their own cables :(

I guess I would need some schematics and to know where to pick

Yeah, maybe it’s just my noob eye, but I don’t see anything that seems to be broken  :/

Yes that’s true, now on the other hand, the floppy connectorl ines/traces are on the bottom side of the PCB and the caps on the top. 

Well, I don’t discard any possibilities, but it didn’t seem the caps had leaked long enough to do that type of damage.  Still not even sure where to look.  *SOMETHING* at least reaches the port OK, because for example the floppy emu does power up, so at least voltage and gnd make it :P

I seem to have read somewhere it uses the SWIM II chip..? Yes, I tried with no hdd attached, same issue :( Everything seems to work ok except the floppy port. 

Thanks for replying, So to start off.. which one IS the SWIM chip? Is it the one right above the floppy connector? I *think* I cleaned it up pretty well, but will check again and also the area in general as you say.  I also read around that the crystal plays a part in there too. Maybe it’s...

Hi all, new to the forum came here looking for some help... I have a Macintosh LC III that was not booting up. I replaced all the caps on the logic board, and voila, sweet chimes and bootup.  When it started, I got the flashing questiong mark disk, meaning no OS found on the HDD. I tried with...
