Amiga 1000 Pal Floppy led connector?!

[abraXXious]

Okiez, working on my Amiga 1000 project at the moment. Have a very minty a1000 with NTSC (yeuch) motherboard and daughter board. Also have a nice pal motherboard.

Have already replaced the NTSC motherboard with the Pal motherboard, BUT, the NTSC motherboard has two wires soldered to legs of a chip (which is piggybacked onto another chip with most its legs cut off! Must be a last minute Commodore botch) which go to the floppy disk led. The Pal a1000 motherboard does not have these wires soldered on. Furthermore, I cannot find any connector on the motherboard to connect the floppy led cable to.

I purchased the pal a1000 motherboard as JUST a motherboard, so Im a little lost. I assume the Pal A1000s had the floppy led cable connected to the actual disk drive, is this correct?

Any help would be appreciated.

Will try to check tonight, but I think there's a flying lead out of the floppy drive itself.

Thanks mate - appreciate it.

I think, because the NTSC a1000 came first and was rather rushed out that it had the piggybacked chip with leads as a bodge up to get a floppy indicator light. Later, when the pal version was developed, they used a neater solution.

I need to know where to hook in the floppy indicator led now that I have transplanted a pal mb into an ntsc casing...

Well, I have 2 PAL A1000s - the early one, based on NTSC motherboard including piggyback board, and a late one without the board.

Both have the LED for floppy access connected to the floppy itself - you can sort of see the cable here:

Thanks for that,

the floppy in my a1200 does not appear to have any two pin connector for a floppy drive light.... is there any standard solder points to go to for a floppy led.....Zetr0, where are you when we need you!

On all the 30mm FB-354 Chinon drives, there are solder points for an activity LED. I'd expect the same to be true of the FZ-354 drives. It should be fairly easy to spot, since it's near where the LED would be if you used a normal bezel.

I'll try and do photos some time, I've learned a hell of a lot about Amiga floppy drives recently!

Thanks Andy, you 'da man!

13 years later, I'm still having this issue: why do some FB-354 LEDs not work, when you solder one in (even one from an FB-354 that came with an LED)? I have several such drives, and basically it's like this: If the drive came with an LED, then the LED works in the given solder connections. If the drive did not come with an LED, then putting one on the same solder connections does nothing. In fact, measuring with a probe shows no voltage changes at all during activity.

it would be great to understand...
