Changes
* '''M1 - D''' Double 3.5" drive with [[FDC|NEC765]], with [[VDOS]] 1.0
These are the original drives from Vortex, for use on CPC 464. The hardware supports one or two 80 track drives, additionally a 3" [[Amstrad Disk Drive|FD-1]] can be connected as third drive, ie. unlike most other CPC disk interfaces it supports more than 2 drives. [[VDOS ]] allocates RAM for only 2 drives though, which of the 3 drives are in-use is selected with |S command.
== Vortex -Z Drives (180K/side or 180K/disk?) ==
* '''F1 - Z''' Single 5.25" drive without FDC, without [[VDOS]]* '''M1 - Z''' Single 3.5" drive without FDC, without [[VDOS]]
These are the ''Low-Capacity'' drives from Vortex, for use on CPC 664/6128 or CPC 464 with DDI-1 (ie. on computers that already have a FDC and AMSDOS). There doesn't seem to be anything special about this product, just an off-the-shelf disk drive, shipped with a CPC-specific connection cable.
* Vortex X modul (adding RS232 support to -X drives)
* VDOS2.0 (upgrading older drives to [[VDOS ]] 2.0)
* Second drive unit (for upgrading a single -S drive to a dual -D drive)
Note: According to the manual, the directory can hold 128 entries under VDOS2.0 (whole 4K used), but only 64 entries under VDOS1.0 (only half of the 4K area used).
The Vortex -Z drives do not seem to include any [[VDOS ]] ROM (so they do support only normal 40-Track AMSDOS Formats, but NOT the 80-Track Vortex format).
