The table below shows values for PC memory module types. These modules usually combine multiple chips on one circuit board. SIMM modules connect to the computer via an 8-bit- or 32-bit-wide interface. RIMM modules used by RDRAM are 16-bit- or 32-bit-wide. [49] DIMM modules connect to the computer via a 64-bit-wide interface.
The written USB 3.0 specification was released by Intel and its partners in August 2008. The first USB 3.0 controller chips were sampled by NEC in May 2009, [4] and the first products using the USB 3.0 specification arrived in January 2010. [5] USB 3.0 connectors are generally backward compatible, but include new wiring and full-duplex operation.
The C64S tape adapter lets you connect your tape deck to a PC parallel port. [22] The Cassadapt tape adapter allows to convert tape programs (T64 and PRG) from a PC to either the Commodore 64 or a C2N tape deck. [23] Disk connector adapters. The 1541-III is a PIC microcontroller controlling a MMC/SD card with .D64 files. It does however NOT ...
The eSATA connector is a more robust SATA connector, intended for connection to external hard drives and SSDs. eSATA's transfer rate (up to 6 Gbit/s) is similar to that of USB 3.0 (up to 5 Gbit/s) and USB 3.1 (up to 10 Gbit/s). A device connected by eSATA appears as an ordinary SATA device, giving both full performance and full compatibility ...
The MSD SD-2 implements the Commodore DOS Duplicate command from the older Commodore PET dual drive series. Because the SD-2 has paired drive units and 6kB of internal RAM, it allows entire disks to be copied in less than 2 minutes. It is still unable to read and write an entire track of data (over 7kB) in a single rotation of the media, which ...
One-bit SD bus mode: Separate command and data channels and a proprietary transfer format. Four-bit SD bus mode: Uses extra pins plus some reassigned pins. This is the same protocol as the one-bit SD bus mode which uses one command and four data lines for faster data transfer. All SD cards support this mode. UHS-I and UHS-II require this bus type.

The 64-bit PCI connector can be distinguished from a 32-bit connector by the additional 64-bit segment. Memory transactions between 64-bit devices may use all 64 bits to double the data transfer rate. Non-memory transactions (including configuration and I/O space accesses) may not use the 64-bit extension. During a 64-bit burst, burst ...
