Re: Logic Analyzer software for the HP-IB/RS-232 bus pre-processor HP 10342B
Oh I know that. At work we have several different types. USBee, Total Phase, etc. They all seem to have various flaws, the most common of which is lack of ground isolation in USB based models. Just seems like a curious omission from their repertoire of post analyzers.

Wow. That is cheap. Anyone ever use it? What are its limitations in real world situations?

The solution used with the HP 10342B RS-232 preprocessor interface was to throw hardware at the problem with a Zilog SIO/1 to turn the serial bits into parallel bytes, along with a Z80 CPU to configure the SIO/1. http://www.bitsavers.org/test_equipment/hp/logic_analyzer_preprocessors/photos/10342B/10432B_T.jpg The 16700 series software has the B4601B Serial Analysis Tool Set. You need to install a license to use that, which has been made available. I have never really tried to do anything with the B4601B Serial Analysis Tool Set and have no idea if it would be of any help for I2C analysis.

Was there ever an I2C decoder created for the 16500/16700? Marc On Wed, May 30, 2018 at 7:07 PM, Curious Marc via cctalk < cctalk@classiccmp.org> wrote: > Wow. Impressive reverse engineering work.

The agIalEngine.cpp source file provided there contains a complete IAL style inverse assembler .R file parser into the variable and constant segment, the instruction opcode segment, and the string segment, plus an interpreter to execute the instruction opcodes. So it was mostly trying to figure out exactly what the agIalEngine.cpp source code does and writing something a similar tool that could execute in a standalone environment, and output text representations of everything in the .R file instead of interpreting and executing it. I hope I can do something similar to figure out the IA file format used by the 1630 series, just for completeness, and maybe be able to write an equivalent to the IALDOWN tools for the 1630 series. It appears that the 1630 series IA files start with the same .R files, then flatten them down to the three segments, then add some header information. But they also break the resulting file in a block structure with a 16-bit checksum on each block using an unknown algorithm. My current plan is to try hooking another logic analyzer up to a 1630 to observe what the 6809 CPU is doing when it computes checksums. I tried using CRC RevEng without any luck. Could be user error and I don't know how to use that tool.

For anyone that does any work with old HP logic analyzer inverse assembler files, it turns out that it is possible to decode the 68000 based logic analyzer IAL style IA binary files back into equivalent source code that can be assembled again with the 10391B ASM.EXE assembler. (No idea yet about the 6809 based 1630 series logic analyzers. Those use a different binary format).

This has probably been asked before, but does anyone have the software package that came with the HP-IB/RS232 HP10342 bus pre-processor for the HP1650 series Logic Analyzer (actually I have a 1670G)? It should have a config file and an inverse assembler file. I'm interested in the HP-IB files. Can't find it anywhere. - Marc
