FLEXTRACT extracts the .CMD files from a Flex .DSK image file. The source code is flextract.c which can be compiled under GCC.
CMD2BIN strips everything in the .CMD file except the binary program code. The source code is cmd2bin.c which can be compiled under GCC.

This provides details of setting up and testing an Arduino based Logic Analyser. This can be done in a Windows, Linux or Mac environment.
Ubuntu 14.04 Set Up InstructionsPicture below shows the set up for testing the Logic Analyser on a Microtan CPU board. IC J4 was chosen as the component to test as its pins have a wide range of clock pulse frequencies present and the reset pin receives a very narrow width clock pulse.
Test Procedure
Attach a Logic Chip Clip to the 74LS393 "J4" IC.
Connect ground jumper (M-F) wire from Arduino pin GND to J4 pin 7.
Test 1 - Testing J4 first set of dividers
Connect test probe jumper (M-F) wires from Arduino pins 8 (Channel 0) to 13 (Channel 5) to J4 pins 1, 3, 4, 5, 6, 2.
Set sampling rate of 4MHz and initiate capture.
Test Results are here.
Test 2 - Testing J4 second set of dividers
Connect test probe jumper (M-F) wires from Arduino pins 8 (Channel 0) to 13 (Channel 5) to J4 pins 13, 11, 10, 9, 8, 12.
Set sampling rate of 4MHz and initiate capture.
