A series of 3.5" and 5.25" floppy disc drives from Vortex providing up to 720K capacity (704K available).

S- and D-Drives (720K)

These are the very first generation of floppy disc drives from Vortex. They came in variants having either a single ("S" variant) or two ("D" variant) DS/DD 80-track drives installed (BASF 6138).

Second Drive Upgrade

Vortex offered an upgrade option that allowed an F1/M1-S single drive to be upgraded to an F1/M1-D dual drive. To do this, one simply had to install an additional drive in the free drive slot of the S-drive housing.

FDA-1 3" Drive Adapter

This adapter allowed to use an Amstrad 3" drive on Vortex F1/M1 setups connected to a CPC 464. Since only two drives can be used simultaneously, the 3" drive had to be manually selected first using RSX commands.

FDC I/O Ports

All type of controllers are based on the NEC 765 chip.

CPC 664/6128:

Z-Drives (180K)

These are basic and less expensive low-capacity drives and were meant to be directly connected to a CPC 664/6128 or CPC 464 with DDI-1 (ie. on computers that already provide a floppy controller). Since these drives do not ship with a special controller, they do rely fully on AMSDOS and thus only 40 tracks can be accessed.

Variants

• F1 - Z Single 5.25" drive with power supply with ribbon cable (does not come with interface containing FDC or VDOS)
• M1 - Z Single 3.5" drive with power supply with ribbon cable (does not come with interface containing FDC or VDOS)

X-Drives (720K)

These are the latest drives from Vortex for use on CPC 464 with DDI-1 or CPC 664/6128 computers (ie. on computers that already have a FDC), so no own FDC was required anymore. Instead, a ROM module was supplied together with the drive, which provided VDOS 2.0-X. Only single-drive variants were available. The |S command (for accessing a third drive) is no longer used, the new |X command allows to swap drive A and B (same as X-DDOS from Dobbertin). These drives are well designed and strong. They are housed in a metal case with power supply (which has good protection with fuses) and have good quality drive mechanisms. The drive has jumpers on it that can be configured as needed.

X(RS)-Modul

The X-drives for the CPC 664/6128 are connected directly to the floppy port. To provide VDOS, a "X-Modul" had to be installed. This was a single-ROM board with VDOS 2.0-X and came in two versions, one of which providing an additional RS232-C interface ("XRS-Modul"). The version for the CPC 464 came with a chunky housing in which both the X(RS)-Modul and the DDI-1 had to be installed.

RS232 I/O Ports

The RS232-C interface of the -XRS modules are suspected to be at least partially compatible with Amstrad/Pace interfaces.
