Looking for logic analyzer for 8bit processor

Hi,
I am looking for a logic analyzer for 8 bit microprocessors like z80, 8085, and 6809, and 16bit 68000.
What is the most recent model that can decode(disassemble) the data bus state listing for these uP?

HP MSO 54645D or 54622D can do this or 1650 series?

Thank you in advance.

Edit: Anyone has Inverse Assembler for 16751, 2, 4?

All of the HP/Agilent/Keysight products to support those processors are long gone, and can't be resurrected.

Emulation Technology (www.emulation.com) used to support these processors, and they still show up on their website: http://www.emulation.com/catalog/off-the-shelf_solutions/logic_analyzer-scope_adapters/preprocessors/hp_preprocessor_table/index.html

It doesn't look like they have any of the HW available, and according to some documents I have, they only supported the 16700 family, and before that the 1650 series. They did not have support for the newer 1680/16800/16900 family.

The MSO's could never do Inverse Assembly, as far as I know. They were strictly Timing analyzers, and Inverse Assemblers required state analysis.

You're probably out of luck.

  Thank you very much for the response.
  
  What was the most recent model of HP logic analyzer that can do decoding 8bit microprocessor without additional software or hardware, do you rember?

    Most logic analyzers, including current ones, can correctly capture data from these processors, handling such issues as bus demultiplexing. That's less than half the problem, however.
    
    You will also need configuration files to correctly classify the signals, and give the the proper names. Those are relatively easy to build.
    
    Once you have that you will need to get inverse assemblers to decode the signals. Those inverse assemblers don't exist, and they will be very hard to build.
