Has Anyone Daisy Chain A1010 Disk Drive With Success¹¹¹

[amiga1084]

Hello All,

I have had and still have many A1010 disk drives and when I
try to Dasisy Chain the drives the 2 second drive does not
work.I have even tried pluging in other Amiga external disk
drives to A1010 but still they don't work.So whats the point
of having external port when it does not work.Like to hear
your comments Merv

Hi,
you've got to open it and change the "DS" jumper to +1 on the drive

[amiga1084]

Hello, Thanks for that why didn't Commodore do it in the factory or mention it in the manual, like other floppy drive makers at the time.Merv

other makers of floppy drives for amiga inclued a built in switch that let you change drive numbers on the outside of case.

I dont think you have to open anything for that specific Drive

I tried it and it works on the A1000 (I think I plugged in 3 external 1010's on it...giving a total of 4)

I used to format 4 disks at once with X-Copy Pro WooHoo!

I think the problem is that your Amiga is NOT supplying enough power to power the extra drive

Yeah I never heard of having to move jumpers or switche to get more drives to work, the switches that were mentioned were usually to disable the drive without having to switch off and remove the drive (to free up some precious RAM for the 512k Amigas back in the day, to get some games to work!)

I had a 1010 and a Cumana drive daisy-chained on my A1200 back in the day.  Don't remember messing with any jumpers though.  Sounds like the 'insuffucent power' problem, as has already been mentioned.

The first batches of A1010 couldn't be daisy-chained, because they didn't supply power to the extrenal connector.

Amiga floppies were designed to daisy chain. There's no need to mess with jumpers.

I do recall some issues with the A2000 wherein the first external floppy became DF2: instead of DF1: and that could be annoying if software assumed it should look for DF1:.  There was a jumper or something on the A2000 mobo or a line to be snipped ot deal with this.  It's been nearly 20 years so my memory is vague.

Cutting / soldering jumpers and moving drive id dip switches have to do with the old 1540/1541 drives for the 8-bit Commodores! The Amiga's drive chain is very different to the old commodore serial bus.

The Amiga's floppy drive daisy chaining works by always having the next DS signal at the same pin (and the ones following it after that) at the external floppy connector.

The external drives just move the next DS signals one pin down at their respective external connectors.

DS 1 2 and 3 are present on the Amiga's ext floppy connector
DS 2 and 3 are present on the first ext floppy drive's daisy chain connector, etc.

Commodore warned against daisy chaining A1010s when connected to an A500, as they draw a lot of current. The slimline aftermarket drives consume less and it's safe to add three of those.

No such jumper. There's only a "DF1 present" jumper on the mobo for connecting a second internal mechanism.

You beat me to it. This is the correct answer, no jumpers or anything involved.
If you do want to fix this, what you have to do is solder the power lines on the passthrough connector.
