+KC 85/4 Z80-based computer, OS main loop trace
+-------------------------------------------------------------------------------
+
+This is a set of example captures of the Z80 CPU operation of the KC 85/4
+by VEB Mikroelektronik Wilhelm-Pieck Mühlhausen.
+
+Details: http://www.mpm-kc85.de/
+
+
+Logic analyzer setup
+--------------------
+
+The logic analyzer used was a SysClk LWLA 1034:
+
+ Probe Signal
+ ------------------
+ CH1 CLK
+ CH2 /M1
+ CH3 /INT
+ CH4 MEI
+ CH5 /WAIT
+ CH6 IEI
+ CH7..CH22 A0..A15
+ CH23 /IORQ
+ CH24 /MREQ
+ CH25 /RD
+ CH26 /WR
+ CH27..CH34 D0..D7
+
+
+Data
+----
+
+Contains two samples, one captured asynchronously at 20 MHz, and another
+captured synchronously on the falling edge of the Z80 CPU clock.
+
+The sigrok command lines used were:
+
+ sigrok-cli -d sysclk-lwla \
+ -c samplerate=20M \
+ -p CH1=CLK,CH2=/M1,CH3=/INT,CH4=MEI,CH5=/WAIT,CH6=IEI,\
