1. SPECIFICATIONS AND COMPATIBILITY
This chapter summarises the unit specifications, provides a
reference regarding compatibility to host systems and a table
of the various MCDISK-D models.
1.1 SPECIFICATIONS
Three MCDISK-D models are available (see table 1.3), iden-
tified by an extension: D-1, D-2 or D-3. In the table below,
model differences are indicated by this extension in parenthe-
sis.

1.2 COMPATIBILITY
MCDISK-D operates with various system platforms using
standard driver software. Some host systems do not fully
support MCDISK-D and require special driver software. MPL
AG provides a "MCDISK Application Note" where two major
subjects are reflected:
• The actual status of software and hardware support for
different host systems, including a description of the cat-
egories of use (file system, binary image transfer, SCSI
level access).
• A list of MCDISK-compatible PCMCIA cards and ATA-
disks, tested by MPL AG or MCDISK users.
