Disc drives from [[Vortex_Computersysteme|Vortex]], with 80 tracks and 720K capacity (704K available).
+
A series of external 3,5" and 5,25" floppy disc drives from [[Vortex_Computersysteme|Vortex]] providing up to 720K capacity (704K available). The Vortex drives were most popular in Germany. For more information regarding [[VDOS]] and the Vortex Disk Format, see the dedicated [[VDOS]] Wiki page.

* '''F1 - S''' Single 5.25" drive with [[FDC|NEC765]], with [[VDOS]] 1.0
+
These are the first generation of 720K floppy disc drives from Vortex. They came in variants having either a single drive ("S" variant) or two drives ("D" variant). The "S" variant (as well as the less expensive "Z" variant) was delivered with the same double-height casing as the "D" variant, so that a second drive could be retrofitted.

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.

The F1-S and F1-D models are based on BASF 6138 (81690-001) type 5,25" disk drives, i.e. double-sided, 80 tracks per side, 96 tpi density.

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.
+
=== A1-S Upgrade Kit (5,25") ===
  
−
Although the drives might have 80 tracks (?), AMSDOS can access only 40 tracks. No info if the drives are double-sided, and if yes, if they do have a side-select switch for accessing the second side?
+
Vortex offered an upgrade kit consisting of a single bare drive and an installation manual, allowing to upgrade a F1-S (single) drive to a F1-D (dual) drive. To do this, one simply had to install the additional drive in the free slot of the drive case.

These are the newest drives from Vortex, for use on CPC 664/6128 or CPC 464 with DDI-1 (ie. on computers that already have a FDC). The |S command (for accessing a third drive) is no longer used, the new |X command allows to swap drive A and B.
+
The M1-S and M1-D models are based on 3,5" disk drives. Controller and DOS were identical for 5,25" and 3,5" devices.

+
This adapter allows to connect an external FD-1 3" drive on Vortex F1/M1 setups on the CPC 464. Since only two drives can be used at the same time, the external 3" drive first had to be selected manually with the RSX command '''|S'''. This RSX command worked also with VDOS 2.11 on CPC6128.

The pictures of the PCB are not clear. There appears to be a jumper and a PAL type chip next to the FDC.  
+
All types of floppy disk controllers for the F1-S/D and M1-S/D series are based on the NEC 765 chip. The manual states that on "controllers having an integrated ROM module/eprommer" (probably the later 6128 interfaces?), the port addresses can be freely configured using a decoder ROM.
−
The manual mentions a 'decoder-ROM' so perhaps this is in the PAL?

These are less expensive drives and were meant to be directly connected as B drive to a CPC 464 with DDI-1 or a CPC 664/6128. Since these drives ship neither with an own controller nor a [[VDOS]] ROM, they do rely fully on AMSDOS and thus only 40 tracks on one side can be accessed, resulting in the same capacity (180K/side) as the 3" drives.

=== F1-Z (5,25") ===
 +
 
 +
The F1-Z model is based on a later revision of the BASF 6138 type disk drive (81757-001), which offers more configuration options using jumpers.  The drive was shipped in a "double step" configuration to use only 40 tracks, and thus the cheaper and more widely available DS DD floppy disks (48 tpi, 180K/side) could be used.

These are the latest drives from Vortex for use with a CPC 464 with DDI-1 or a CPC 664/6128 (ie. on systems that already have a floppy disc controller); no additional controller 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).
 +
 
 +
=== F1-X and F1-XRS (5,25") ===
 +
 
 +
The F1-X model is based on either a single BASF 6138 (81690-001) or a single BASF 6139 5,25" disk drive. The BASF 6139 is a revisioned version which is slightly more compact (~1cm shorter), and also a number of electronical and mechanical design flaws that affected durability were corrected. The F1-XRS variant is equipped with an additional RS232-C interface.

== Germanized-English RSX Commands and VDOS differences compared to AMSDOS ==
+
=== X(RS)-Modul ===
  
−
* Vortex apparently considered the normal AMSDOS RSX commands |TAPE.xx and |DRIVE/|USER too difficult for german users, and changed them to |CAS and |SELECT (which resemble equivalent german words ''Kassette'' and ''Selektieren''). This is making VDOS slightly incompatible with AMSDOS and all other AMSDOS clones (except for Dobbertin's X-DDOS, which supports both the english and germanized dialects).
+
The X-drives for the CPC 664/6128 are connected directly to the floppy port. In order to provide [[VDOS]], the "X-Modul" (sometimes also called "VDOS module") must be connected additionally to the expansion port. This contains a ROM board that provides a VDOS 2.0-X ROM. The ROM board supplied for the CPC 464 came together with a chunky housing in which both the "X-Modul" and the DDI-1 controller were installed. All variants were also available with an additional RS232-C interface (in this case called either "XRS-Modul" or "X-Modul/RS").  
  
−
|SELECT is used to both select user and/or drive. e.g. |SELECT,"3" for user 3, |SELECT,"B" for drive B, |SELECT "4B" for user 4 on drive B. VDOS doesn't have USER or DRIVE commands.

A series of external 3,5" and 5,25" floppy disc drives from Vortex providing up to 720K capacity (704K available). The Vortex drives were most popular in Germany. For more information regarding VDOS and the Vortex Disk Format, see the dedicated VDOS Wiki page.

S- and D-Drives (720K)

These are the first generation of 720K floppy disc drives from Vortex. They came in variants having either a single drive ("S" variant) or two drives ("D" variant). The "S" variant (as well as the less expensive "Z" variant) was delivered with the same double-height casing as the "D" variant, so that a second drive could be retrofitted.

F1-S and F1-D (5,25")

The F1-S and F1-D models are based on BASF 6138 (81690-001) type 5,25" disk drives, i.e. double-sided, 80 tracks per side, 96 tpi density.

  • F1-S/D system disk
    (CPC 464)

  • F1-S/D system disk
    (CPC 664/6128)

A1-S Upgrade Kit (5,25")

Vortex offered an upgrade kit consisting of a single bare drive and an installation manual, allowing to upgrade a F1-S (single) drive to a F1-D (dual) drive. To do this, one simply had to install the additional drive in the free slot of the drive case.

M1-S and M1-D (3,5")

The M1-S and M1-D models are based on 3,5" disk drives. Controller and DOS were identical for 5,25" and 3,5" devices.

FDA-1 3" Drive Adapter

This adapter allows to connect an external FD-1 3" drive on Vortex F1/M1 setups on the CPC 464. Since only two drives can be used at the same time, the external 3" drive first had to be selected manually with the RSX command |S. This RSX command worked also with VDOS 2.11 on CPC6128.

RSX Description
|S,1 Use 3" drive as drive A, upper Vortex drive is disabled
|S,2 Use 3" drive as drive B, lower Vortex drive is disabled
|S,0 Disable the 3" drive (default)

  • FDA-1 Adapter

  • Plug (cable side)

  • FD-1 3" floppy drive plug

FDC I/O Ports

All types of floppy disk controllers for the F1-S/D and M1-S/D series are based on the NEC 765 chip. The manual states that on "controllers having an integrated ROM module/eprommer" (probably the later 6128 interfaces?), the port addresses can be freely configured using a decoder ROM.

CPC 464:

Address Description
0xFB7E uPD control
0xFB7F uPD data
0xFA7E motor on/off

CPC 664/6128:

Z-Drives (180K/side)

These are less expensive drives and were meant to be directly connected as B drive to a CPC 464 with DDI-1 or a CPC 664/6128. Since these drives ship neither with an own controller nor a VDOS ROM, they do rely fully on AMSDOS and thus only 40 tracks on one side can be accessed, resulting in the same capacity (180K/side) as the 3" drives.

F1-Z (5,25")

The F1-Z model is based on a later revision of the BASF 6138 type disk drive (81757-001), which offers more configuration options using jumpers. The drive was shipped in a "double step" configuration to use only 40 tracks, and thus the cheaper and more widely available DS DD floppy disks (48 tpi, 180K/side) could be used.

  • BASF AG 6138 (81757-001) 40 track jumper configuration

A1-Z Upgrade Kit (5,25")

Vortex offered an upgrade kit consisting of a controller, a manual, a CP/M license and an utility disk which allows a F1-Z drive to be upgraded to a F1-S drive.

M1-Z (3,5")

The M1-Z model is equipped with a single 3,5" disk drive.


X-Drives (720K)

These are the latest drives from Vortex for use with a CPC 464 with DDI-1 or a CPC 664/6128 (ie. on systems that already have a floppy disc controller); no additional controller 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).

F1-X and F1-XRS (5,25")

The F1-X model is based on either a single BASF 6138 (81690-001) or a single BASF 6139 5,25" disk drive. The BASF 6139 is a revisioned version which is slightly more compact (~1cm shorter), and also a number of electronical and mechanical design flaws that affected durability were corrected. The F1-XRS variant is equipped with an additional RS232-C interface.

M1-X and M1-XRS (3,5")

The M1-X model is based on a single NEC FD1035 type 3,5" disk drive. The M1-XRS variant is equipped with an additional RS232-C interface.

X(RS)-Modul

The X-drives for the CPC 664/6128 are connected directly to the floppy port. In order to provide VDOS, the "X-Modul" (sometimes also called "VDOS module") must be connected additionally to the expansion port. This contains a ROM board that provides a VDOS 2.0-X ROM. The ROM board supplied for the CPC 464 came together with a chunky housing in which both the "X-Modul" and the DDI-1 controller were installed. All variants were also available with an additional RS232-C interface (in this case called either "XRS-Modul" or "X-Modul/RS").

  • XRS-Modul (CPC 464)

  • XRS-Modul with built-in DDI-1 visible (CPC 464)

  • XRS-Modul board beneath the DDI-1 (CPC 464)

  • XRS-Modul board backside (CPC 464)

  • X-Modul (CPC 6128)

  • X-Modul board (CPC 6128)

  • X-Modul board backside (CPC 6128)

RS232 I/O Ports

The RS232-C interface of the "XRS-Modul" was advertised to be compatible with Amstrad/Pace interfaces, but offers only one channel (so no channel B).

Address Description
0xFADC SIO data (R/W)
0xFADD SIO control (R/W)
0xFBDC 8253 counter 0 (R/W)
0xFBDD 8253 counter 1 (R/W)
