Vortex Disc Drives

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

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 464:

CPC 664/6128:

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)

These are the latest drives from Vortex for use on CPC 664/6128 or CPC 464 with DDI-1 (ie. on computers that already have a FDC). 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.
