Logic Analyser page

OLS The OLS provides 32 digital channels all 5V tolerant (with the wing). It is a cool device and supported by sigrok/PulseView. Alas, it seems to be discontinued. It is completely open source, but still someone has to produce them. The OLS is a FPGA based device.

GusmanB The GusmanB Logic Analyzer is based on the Raspberry Pi Pico and has 24 channels per board, up to five boards can be chained. It has its own graphic front-end, but supports the decoders written for sigrok/PulseView.
The case is still temporary, but works very well.

Adapters &
Patch boards

The direct approach while connecting Logic Analyzers is using wires with clips directly to the Analyzer inputs. This might work great, but it takes lots of time to make all those connections without errors, and you have to break it all up for the next project.

As most of my debugging is on vintage microprocessor boards, I created adapters to break out all processor pins to a header. these breakout-adapters could be used standalone, but I also have processor specific patch boards, which organize the signals into logical groups, making is easier (=less patch errors) to connect it to the L.A.

The idea is to organize the signals into grouped channels suitable for the Logic Analyzer. In this case the two 18 pin headers match those on the OLS.

TMS7000
decoder
On the software side the data-, address- and control-lines can be interpreted as data transferred over busses. In this case only the data and address bus are interpreted as hexadecimal values.
It took a while to understand the framework for the decoders, and its usage is for now limited to a view of the address and data bus.

These decoders can be supplemented with a complete disassembler, but even a simple address-/data-bus decoder is useful in combination with a listing or disassembly.
