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. |
