SIM4-02 HARDWARE SIMULATOR 1.0 INTRODUCTION The SIM4-02 Hardware Simulator is a program written for the MCS-4 ™ series Micro Computer System. This program will provide interactive control over the debugging of other MCSA ™ programs. The minimum configuration requited is a SI M4-02 prototype card with three 4002 RAMs and a Teletype. When fully s ...

A breakpoint register is associated with the simulated execution mode of operation, allowing the user to pre-set a location which will cause an interrupt before execution. The BREAK key on the teletype may also be used to interrupt execution and some other types of output. During'simulated execution, a count is kept of the number of simulated ...

A Accumulator This directive may be used to display and/or alter the contents of the simulated accumulator. A space or comma follow- ing the A will display in binary, the contents of the simulated accumulator. This or the A may be followed either by a new value to be entered, or by a carriage return to end the directive. C Carry/Link This directive ...

5.0 ERROR MESSAGES Most of the errors which can be detected by the simulation program are identified by a single character typeout, followed by ringing the bell once. Six different types of errors are identified this way: CODE SIGNIFICANCE ? This is not a valid directive. Any printed graphic normally generated by the ASR33, which is not a valid dir ...

return address using the L directive. That may then be pushed down with the S directive, so that the starting address may be loaded into the first subroutine level, or the process may be repeated up to three times. If it is desired to force an inter~ rupt at the first occurrence of a JMS instruction, the stack pointer may be set to 3 initially, so ...

the typing of some specializ~d sequences of characters, partial decimal to binary conversion on input, and 6-bit teletype char- acter input with control character checking. A test program may use these subroutines to facilitate checkout of complex programs, or the ROM may be included in the final program if teletype interface and the same ancillary ...

8.0 RAM USAGE The simulation program, to facilitate full usage of the RAM, has organized it into a nominal block of 64 registers, each containing 16 main memory locations and four status locations. Directives which reference RAM as such (i.e., 0, M, and 0), always address it by a register number, and sometimes by a character position within the reg ...

The bank number in the chart above is the value of the accumulator during a DCl instruction, needed to address that bank of RAMs. The port number given corresponds to the number typed out during simulation of the WMP instruction. Register positions 16-19 (Le., the status locations) are normally addressed in the program by the RDO/WRO, RD 1 /WR 1, e ...
