OK - now you can continue to morning… 
The output pin 9 looks OK too.
Do you get every time this same waveform if you press the sine button of the generator several times?
If yes - then it seems this section of the circuit is working OK.
Maybe it is good idea to try to change the 74F161 tomorrow.
Although now I live about 10 years so with this device, but it certainly does not leave me this thing to rest me. But now it is indeed the last today.
No, unfortunately, the IC2 pin to 9 form a random sign.
To be continued…

In the next tests we try to find out the reason to the bad signal on pin 9 of IC2.
Very accurate timing and amplitude measurements will be needed:
On switchable X1/X10 probes, set the switch to X10 position.
In the oscilloscope select DC coupling, 0.15V/div and 0.1ms/div ranges.
Set trigger OFF.
Touch the tip of the probe to the test output on the rear of the PCS500 oscilloscope.
Adjust the compensation trimmer on the probe for the optimum square wave:
More instructions coming soon…
Select DC coupling on both channels.
With x10 probe setting, select 0.15V/div, 0.1ms/div, trigger CH1
Connect CH1 to pin 9 of IC2. (Will be there all the time.)
Connect CH2 to pin 14 of IC2.
Click the sine button of the generator.
Adjust the traces as in this image:
Now settings are OK - you can clear the history memory.
Click Run button off.
Click “History” button.
Right-click on history bar.
Select “Clear History”.
Now the tests can start.
Click Run on.
Keep CH2 connected to pin 14 of IC2 and repeat clicking the sine button until something strange is seen several times on pin 9 of IC2.
Move the CH2 to pin 11 of IC2 and continue pressing the sine button until something strange is seen several times on pin 9 of IC2.
Next connect CH2 to pin 12 of IC2 and continue pressing the sine button until something strange is seen.
Then connect CH2 to pin 1, pin 2 and finally pin 3 of IC22.
In each case continue pressing the sine button until something strange is seen several times on pin 9 of IC2 .
When done click the Run button “up”.
Right-click the history bar and select “Save History”.
Compress the saved history file to ZIP and then you can mail it to me.
I hope this large test gives some information of the root cause of the problem…
Hi, E-mail sent!
Thank you!

Thank you for the data.
It was good idea to put the different pin results to different history files!
I think the IC22: VK8016 (GAL22V10) may be defective.
I sent you an e-mail explaining how to proceed to get a new one…
Dear Vel255!
I say thank you the fast help to everybody very much, a superb team!
I can recommend the Velleman with a good heart only.

The K8016 was perfect, see the picture:
