In the 1980s, it wasn't at all uncommon to see software development houses use a more powerful computer to create and debug software for a less powerful machine. In this spirit, rpcDrive is a mod for Minecraft which adds cross-mod compatibility between RedPower 2's Disk Drives and ComputerCraft's Computers, allowing using Lua scripts to read data from and write data to RedPower 2's 65EL02-based computer ecosystem.

In addition, the mod comes with a built-in (automatically installed) utility called rpc/drive, which allows performing basic read, write and copy operations on RP2 floppies.

ComputerCraft API Documentation

RP2 Disk Drives are registered as peripherals of type rp_drive. It is important to note that Floppy Disks from that mod are operated on in terms of 128-byte sectors; the rp_drive peripheral provides an internal 128-byte buffer, from which sectors are read from and written to.

Indexes and sector counts are provided 1-indexed, as is the case across Lua.

Name	Arguments	Description
isPresent	-	Returns true if a floppy disk is present.
hasData	-	Returns true if a floppy disk contains data.
isReadable	-	Returns true if the inserted floppy disk can be read from.
isWritable	-	Returns true if the inserted floppy disk can be read from.
getSerialNumber	=> string	Returns the floppy disk's internal identifier (its "serial number") in the form of a string.
getLabel	=> string	Gets the floppy disk's displayable label.
setLabel	newLabel (string)	Sets the floppy disk's displayable label.
getBytesPerSector	=> number	Returns the number of bytes in a sector; typically 128.
getSectorCount	=> number	Returns the number of sectors currently written to the inserted floppy.
getSectorSize	=> number	Returns the number of total sectors on the inserted floppy, including ones which have never been written to.
readSector	sectorIndex (number)	Read a sector from the disk to the internal buffer.
writeSector	sectorIndex (number)	Write a sector from the internal buffer to the disk.
erase	-	Erase the floppy disk's contents.
initialize	-	Initialize an empty floppy disk; this gives it a new serial number. Note that writing a sector to an empty floppy disk initializes it automatically.
getBufferByte	index (number)	Read a byte from the internal buffer.
setBufferByte	index (number), value (number)	Write a byte to the internal buffer.
