Hi, I'm working on a Classic board that does the exact same thing. It will boot from a floppy but takes a very long time, probably around 5 or more minutes to boot to the desktop. It boots fine from a good hard drive and passes all logic board test on the Snooper v2.0 test utility. If I boot...

I have an SE/30 with much the same symptoms that I had to set aside because I spent way too much time on it with little progress. https://68kmla.org/bb/index.php?threads/se-30-only-boots-from-system-6.36379/ Have you made any more progress? Your statement about system 7 looking at the serial...

Update I have verified that the clock keeps time and brightness, sound, and mouse settings all survive a reboot.  I've also run a few ram test programs under system 6 and they did not find any problems.  The ram test in the Snooper testing program crashed with a Buss Error.  I don't know if...

I know it sounds like a software issue but for that to be the case, all of the following would have to be true: 1 - Over 50 logic boards that I have repaired using my testing drive with system 7.1 have some sort of hardware problem that ignores a bad system folder. 2 - All my original Apple...

It happens at the same point each time.  A few seconds after the "Welcome To Macintosh" appears, the mouse pointer shows up in the top left of the screen. and the hard drive activity stops.  Moving the mouse does move the pointer on the screen. I haven't hit the interrupt switch but I will try...

Thanks to everyone that has responded to my issue so far.  I worked on the board more today with no success.  It boots fine from a floppy with system 6.08 and mounts the hard drive that I use for testing.  This SE/30 board will not boot from a hard drive or floppy that have any version of system...

I won’t be getting back to the board until tomorrow.  I’ve tried my 7.1 and 7.5 hard drives, both boot up to the “Welcome to Macintosh” screen and then locks up at that point.  It won’t boot from any system 7.X disk tools floppy either.  Both of my system 7 hard drives as well as my floppy disk...

I tried to make it clear that all the components connected to the problem board are good.  They all work properly with my several good SE/30 logic boards.  The ROM Sim is the stock Apple version and I tried several good ones that I have with the same results.  The hard drive has system 7.1...

I'm repairing an SE/30 logic board for a friend and have a problem with booting up with system 7.  I don't have any history with this board, but it had some corrosion in the battery holder but was otherwise very clean.  I have successfully recapped and repaired over 50 logic boards, and this...

I've searched the forum but couldn't find an answer to this.  I would like to work on the analog board without being connected to a CRT and logic board.  I have a problem in the low voltage power supply section and it would be much easier to work on out in the open.  I would use an old hard...
