Floppies
~~~~~~~~
The A3000 has two mounting locations for internal floppy drives.
These are custom designed for the Chinon FB354 and FB/FZ357A, which the
front panel LED and eject button are specific. The slimline models of the
high density drives may require some tinkering to fit properly. Factory
configured, the first internal drive is the one to the left. Of course,
this can vary. An unused bay, or one occupied by an hard disk, should be
covered with the custom moulded textured front cover part.

The two models from Commodore are the A3010, the Chinon FB354,
880KByte double density, and the A3015, the Chinon FB/FZ357A, 1.76MByte
high density. Note this is not the FZ357, without the A designation. The
FZ357A was designed specifically for Commodore and is out of production,
the FZ357 is actually still in active production and is found in many PC
clones. It is not compatible with the slow spin rate required by the Amiga
custom chipset.
There has been much talk about modifying PC high density industry
standard drives to work by dividing the motor control output with a flip flop
or something similar. No definitive plans have showed up. The easiest way
is to acquire a third party model or a used A2015/3015/4015.
All drives should be jumpered as DS0, Drive 0. This is contrary
to PC convention, where all drives are DS1. DF0:, the first Amiga floppy,
is set as DS0, on a connector without the flip in the cable. The second
floppy, DF1: should be on the connector with a flip in the cable, but still
set as DS0. Power is supplied from the mini 4 pin floppy power connector,
and the drive is secured to the drive tray with a set of screws.
To set the machine for two internal drives, remember to jumper the
motherboard accordingly:
