Description

The MVME147SA-2 package is a powerful evaluation and debugging tool for systems built around the MVME147 monoboard microcomputer. Facilities are available for loading and executing user programs under complete operator control for system evaluation. The MVME147SA-2 includes commands for display and modification of memory, breakpoint capabilities, a powerful assembler/ disassembler useful for patching programs, and a self test power up feature which verifies the integrity of the system. Various 147Bug routines that handle I/O, data conversion, and string functions are available to user programs through the TRAP #15 handler.

Because MVME147SA-2 is command-driven, it performs its various operations in response to your commands entered at the keyboard. The flow of control in normal MVME147SA-2 operation is illustrated in Figure 1-1. The flow of control in system 147Bug operation is illustrated in Figure 1-2. When a command is entered, MVME147SA-2 executes the command and the prompt reappears. However, if a command is entered which causes execution of your target code (for example, GO), then control may or may not return to 147Bug, depending on the outcome of the program. The commands are more flexible and powerful than previous debuggers. Also, the debugger in general is more “user-friendly”, with more detailed error messages (refer to Appendix B) and an expanded online help facility.
Turn all equipment power OFF. Configure the header jumpers on the module as required for your particular application. For the MVME147, MVME147A, MVME147-1, and MVME147A-1 the only jumper configurations specifically dictated by MVME147SA-2 are those on header J3. Header J3 must be configured with jumpers positioned between pins 2-4, 3-5, 6-8, 13-15, and 14-16. This sets EPROM sockets U1 and U2 for 128K x 8 devices. This is the factory configuration for these modules. For the MVME147S, MVME147SA, MVME147S-1, MVME147SA-1, MVME147SA-2, MVME147SB-1, MVME147SC-1, and MVME147SRF the only jumper configurations specifically dictated by 147Bug are those on header J2. Header J2 must be configured with jumpers positioned between pins 2-4, 3-5, 6-8, 13-15, and 14-16. This sets EPROM sockets U22 and U30 for 128K x 8 devices. This is the factory configuration for these modules.
