Disc drives from [[Vortex_Computersysteme|Vortex]], with 80 tracks and 720K capacity (704K available).
== Vortex -F1/M1 S and -and D -Drives (720K/disk) ==
* '''F1 - S''' Single 5.25" drive with power supply connected via ribbon cable to interface with [[FDC|NEC765]] and [[VDOS]] 1.0 or 2.11
See below.
== Vortex F1/M1 Z-Z Drives (180K/side or 180K/disk?) ==
* '''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 ''Lowlow-Capacitycapacity'' 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. Since this drive fully relies on AMSDOS can , only access 40 trackscan be accessed.
TO BE CONFIRMED: Are the drives 80 track, double sided? Is there any way to access the second side with AMSDOS (e.g. side switch??)
== Vortex -F1/M1 X -Drives (720K/disk) ==
* '''F1 - X''' Single 80 track, Double Sided, 5.25" drive with power supply and ribbon cable which connects to interface containing [[VDOS]] 2.0
* '''M1 - XRS''' same as M1-X, upgraded with RS232 interface
These are the newest latest 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 (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.
