Amiga 1000 boot problem(s)

[save2600]

It *IS* normal for an A1000's power LED to flash like that upon power up. What's strange is that the computer does not seem to continue booting after Kickstart loads. Perhaps the disk is bad, drive is bad, no daughtercard and no 1050 256k front memory.

I'd try making a new KS disk on a double density disk and try writing 1.0-1.3.

Yeah, since it worked last time you used it 10 years ago and depending where you
stored it - I wouldn't be surprised if the drive has become magnetised, dirty or misaligned.
Maybe try cleaning it with a floppy drive cleaner or if you don't have one, a Q-tip and
(preferably) tape head cleaner and failing that, rubbing alcohol.

Oh and may we assume that there's nothing on the side expansion bus contributing
to this poor thing not booting?

After writing a new KS disk and it STILL doesn't work, you could always swap the
500's floppy with the A1000's as a last ditch shotgun attempt at troubleshooting.
They say not knowing is "half" the battle...  lol

I wonder if the grounding mods recommended to A1000s might help in this case?

That mod usually pertains to adding external stuff to the bus, but wouldn't hurt I guess.

Since he swapped in his A500 drive and was met with the same results, sure sounds like the KS disk is bad or there's something else going on with the Mobo. I'm betting the disk is bad. Wonder if he's using a high-density disk formatted to DD...

Happy to hear your A1000 is A-OK. Enjoy :-)
