Flock V2 is an RCBus floppy disk controller (FDC) and real time clock (RTC) module. It designed to work with RomWBW firmware, supporting CP/M, ZSDOS, and various applications under these OSes.

Note that RCBus is backwards compatible with RC2014 project, and this module will also work with RC2014-based systems.

Flock V2 is based on Western Digital WD37C65B FDC and Maxim Integrated DS1302 RTC ICs.

Flock V2 supports two floppy drives, using IBM PC-like cable with twisted Disk Select / Motor Enable wires between two drives.

Supported floppy disk formats:

• 3.5", 720 KB
• 3.5", 1.44 MB
• 5.25", 360 KB (in 5.25", 360 KB drives only)
• 5.25", 1.2 MB
• 5.25", 360 KB diskettes in 1.2 MB drive (Not supported by RomWBW, requires Y3, C10, and C11 to be installed. Note that these components are not supplied with the kit)

What is included

The kit includes all the components necessary to build the Flock V2 Module: The PCB, 5 integrated circuits, 16 MHz and 32768 Hz quartz crystals, capacitors, resistors, resistor array, and connectors.

The CR2032 battery is not supplied, due to the shipping limitations.
