(Pro/Auto/AutoPro)
The Allegro Mini controller, like the Allegro from Micro System Designs, Inc.,
formats and writes data to a disk in one disk revolution instead of two.
This results in faster duplication speed when writing to unformatted media
and also improves the copy quality by removing the write splices between the
data sectors of the diskette.
Unlike the Allegro, the Allegro Mini does not support SDS (Simultaneous
Double Sided) and 2XSDS (Double Speed Simultaneous Double Sided) drives.
It does support regular speed and 2X drives.
When using the Allegro Mini controller, make sure that "Format" is set to
"Always" to enable the format-with-write feature.
The Allegro Mini controller card comes pre-set with the recommended default
jumper settings.
Default Jumper Settings for the Allegro Mini:
ADDRESS: 370
IRQ: 6
DMA: 2
Note:
When changing the DMA channel, be sure to move all three jumpers to the
corresponding channel at the same time.
