GENERAL OVERVIEW

The LPR/1750 Pace 1750A Preprocessor provides a complete interface between the PACE1750A target system and the Hewlett-Packard 1650/51, 1660C/CS & 16500/510 Logic Analyzers. The Preprocessor provides an easy and convenient way to connect the Pace 1750A signals to the Logic Analyzer.

The LPI/1750 PACE1750A inverse assembler will display the captured data in MIL-STD-1750A mnemonics, once the configuration file is loaded into the Logic Analyzer and the Analyzer is connected to the target system. Decoded status information provided by the inverse assembler includes:

Memory Read
Memory Write
I/O Read
I/O Write
Operand Fetch
Unused pre-fetch

Two Logic Analyzer configuration files are supplied on a 3 1/2" diskette, providing all the necessary formats required to use the preprocessor. One configures the Logic Analyzer to de-multiplex the IB bus and only needs 23 channels to provide complete disassembly. Probing physical addresses in MMU configurations is possible with the second configuration file supplied.
