As explained in Chapter 7 of the "SYM Reference Manual", the vertical input, ground and trigger input of the oscilloscope are to be connected to the "Scope Out" connector AA on the SYM-1 board. The "Oscilloscope Output Driver Software" code provided in this chapter of the manual is to be entered into the SYM-1's memory and executed to enable ...
The 65xx family of microprocessors, consisting of the MOS Technology 6502 and its derivatives, the WDC 65C02, WDC 65C802 and WDC 65C816, and CSG 65CE02, all handle interrupts in a similar fashion. There are three hardware interrupt signals common to all 65xx processors and one software interrupt, the BRK instruction.
The 6502 instruction set includes BRK (opcode $00), which is technically a software interrupt (similar in spirit to the SWI mnemonic of the Motorola 6800 and ARM processors). BRK is most often used to interrupt program execution and start a machine language monitor for testing and debugging during software development.
Free and open-source software portal; GeckOS is a multitasking operating system for MOS 6502, and compatible processors such as the MOS 6510. [1] The GeckOS operating system is one of the few successful attempts to implement a Unix-like operating system on the 6502 architecture.
The 65C02 is a low cost, general-purpose 8-bit microprocessor (8-bit registers and data bus) with a 16-bit program counter and address bus.The register set is small, with a single 8-bit accumulator (A), two 8-bit index registers (X and Y), an 8-bit status register (P), and a 16-bit program counter (PC).
A pair of adult female right whales, Koala and Curlew, have mystified researchers this winter as they cruised south along the Florida coast, then made a surprise appearance this week off Alabama ...
The Junior Computer was a virtual clone of the KIM-1, only it did not use the special I/O+ROM chips but rather an off-the-shelf 6532 RIOT and a 2708 1K EPROM. It also had a different physical shape, as it used the Eurocard board , and a 31-pin DIN connector for I/O and a DIN 41612 connector for system expansion.
In a recent interview with Elle, “The Last Showgirl” star Pamela Anderson discussed how it feels to miss out on an Oscar nomination for best actress. Anderson, who scored noms at the Golden ...
