#External disk drive
5 messages in this thread
When I bought my A500 years ago, I also bought an A1010 drive. The
"manual" that came with it said that you shouldn't cascade A1010s together as
they would put to much strain on the power supply. It said to use an external
drive with it's own power supply if you wanted to use more than 1. I've called
several dealers looking for such a drive, but nobody has one-or has ever heard
of one. Were such drives made? If they were, what were they called?
Has anyone had any experience with putting more than a singal external
floppy on an A500? Can they be cascaded without damaging the power supply?
In a worst case situation, I could always cobble up a supply for the first
drive in the system, since they only seem to want +5 and +12 V., but I'd like
to avoid that if it isn't needed. Yes, I'm using the stock A500 power supply,
and it's driving the computer and a Supra RAM with 4 megs of memory.

Barry,
Yes…that'd be too much for the power supply…best to build one up,
and if you can…use it for both external drives.

Thanks for the information, Don. I can't find any specs on the power supply for
the A500. Do you know them off hand? Actually, it would be better to know the
power requirments of the drives. I've found a great deal on +5/+12 switching
power supplies, but don't know wether one will be enough for two drives (12V
2.6A), 5V 1.8A).
Barry
Barry,
Sorry…I don't remember the specs on the power supply, only that it's
barely capable of running the 500, let alone two external floppies and the
added RAM you say you have.
Don
Thanks anyhow, Don. I think the power supply is 5 amp. What I needed to know
was the draw of the disk drives. One had it printed on the bottom-260ma, way
below the power supply I'm going to use.
