The 6530 ROM-RAM-I/O-Timer (RRIOT) was an integrated circuit made by MOS Technology, as well as second sources such as Rockwell. It was very similar to the MOS 6532 RIOT, but it incorporated 1 KB of ROM, in addition to the chip's other features. The static RAM, however, was reduced from 128 bytes to 64. Due to the very high degree of integration provided by this chip, it was often used in situations that today would be handled by a microcontroller. MOS Technology, Inc. ... Rockwell can refer to: Rockwell International - a defense company in the United States Rockwell Automation - an industrial automation company that descended from Rockwell International Rockwell Collins - a communications and aviation electronics company that also descended from Rockwell International Willard Rockwell - businessman who helped shape and name what became Rockwell International... MOS 6532 RIOT is integrated circuit which contains 128 bytes of RAM, timer and two 8 bit I/O gate. ... A kilobyte (derived from the SI prefix kilo-, meaning 1000) is a unit of information or computer storage equal to either 1024 or 1000 bytes. ...

The form factor was a JEDEC-standard 40-pin ceramic or plastic DIP. Form factor refers to the linear dimensions and configuration of a device as distinguished from other measures of size (for example Gigabytes; a measure of storage size): in computing, form factor is used to describe the size and format of PC motherboards (see AT, ATX, BTX), but also of hard... JEDEC stands for Joint Electron Device Engineering Council and is the semiconductor engineering standardization body of the Electronic Industries Alliance (EIA), a trade association that represents all areas of the electronics industry. ... Fixed Partial Denture, or Bridge The word ceramic is derived from the Greek word κεραμικός (keramikos). ... Household items made out of plastic. ... ICs in DIP14-Package Several PDIPs and CERDIPS. The large CERDIP in the foreground is an 8080 processor. ...
