21/03/2021 · MOS Technology 6502 and other 650x/651x processors are a family ofinexpensive 8-bit microprocessors. 6502 and 6512 processors could address 64KB of memory,other CPUs in the family could address up to 8 KB. Stack size of the 6502was limited to 256 bytes.

The MOS Technology 650X family represents a conscious attempt of eight former Motorola employees who worked on the development of the 6800 system to put out a part that would replace and outperform the 6800, yet undersell it.

In April 1976 MOS Technology built the KIM-1 single-board computer as their 650x products could not use the architecture of existing PCBAs. It featured a single 6502 microprocessor, two 6530 arrays, machine language monitor on 2 kB ROM , 1 kB RAM , fifteen I/O pins, a hexadecimal keypad, LED display, an audio cassette interface and a serial teleprinter interface.

Find out information about MOS Technology 65xx. A family of microprocessors from MOS Technologies, based on the design of the Motorola 6800 . The family included the 6502 used in several early personal...

By June 1975 MOS Technology had created a few working versions from their new MOS Technology 650x family of microprocessors; with prices set at US$20-$25 compared to US$200 for the Motorola 6800....

10/08/2016 · I was reading about undocumented opcodes for the 650x family of processors and discovered JAM, an instruction "which simply causes the CPU to freeze, requiring a hardware reset or power cycle to restart." 1. Was this instruction ever used in practice/production software? What is a use case for this instruction?

MOS Technology was a semiconductor designer and manufacturer based in Norristown, Pennsylvania. It is most famous for the 6502 microprocessor. In late 1976, Commodore Business Machines (CBM) acquired MOS. Chuck Peddle, leader of the 650x group at MOS designed the KIM-1 and it was created primarily to “show off” the 6502 chip to engineers.

09/10/2016 · MOS Technology created two development systems that engineers could use to prototype computers and other devices. The MDT-650 was a single-board computer, as was the KIM-1, which became very popular among computer hobbyists. The KIM-1 soon had company when Steve Wozniak designed the Apple 1, Apple’s first computer and only kit computer.
