Parallel ATA (PATA), originally AT Attachment, also known as Integrated Drive Electronics (IDE), is a standard interface designed for IBM PC-compatible computers. It was first developed by Western Digital and Compaq in 1986 for compatible hard drives and CD or DVD drives.
Moving the HDD controller from the interface card to the disk drive helped to standardize the host/controller interface, reduce the programming complexity in the host device driver, and reduced system cost and complexity. The 40-pin IDE/ATA connection transfers 16 bits of data at a time on the data cable.
IDE64 v3.1 –In 2001 a redesigned version of the 2.1 cartridge was made, this version drops the expansion port pass-through. IDE64 v3.4 –CompactFlash cards became popular, so the cartridge was redesigned in 2004 to include a CF socket. This allowed a mobile and small storage possibility for the C64, without additional devices and power supplies.
When a SATA controller is configured to operate in IDE Mode, the number of storage devices per controller is usually limited to four (two IDE channels, master device and slave device with up to two devices per channel), compared to the maximum of 32 devices/ports when configured in AHCI mode.
Each generation of floppy disk drive (FDD) began with a variety of incompatible interfaces but soon evolved into one de facto standard interface for the generations of 8-inch FDDs, 5.25-inch FDDs and 3.5-inch FDDs. [1]
Modern expansions are possible for the Model D, including the use of an XT-IDE 8-bit ISA card, which provides a Parallel ATA IDE port for hard disk drives and a compact flash card. Users wanting to use the XT-IDE in the Model D must set the address of the XT-IDE card within its BIOS to 340h, as not to conflict with the real-time clock address ...

If no printer port is present at 0x3BC, the second port in the row (0x378) becomes logical parallel port 1 and 0x278 becomes logical parallel port 2 for the BIOS. Sometimes, printer ports are jumpered to share an interrupt despite having their own IO addresses (i.e. only one can be used interrupt-driven at a time).
