I took the one from:

 https://sourceforge.net/p/vice-emu/bugs/_discuss/thread/
538e31942f/ba33/attachment/cia-shiftregister-tests.zip

There's discrepancy on the naming between readme and files: 

... Now run the "delay2-new" and "delay-old" ...

there's "delay2-old. But..

Both CIAs are marked 1386 (I expect it to be "new")

First prgs give green. The "delay2*" prgs seem to insist that I have "old" CIA(s): "new" gives red, "old" gives green. Then the remaining prgs all "old" give red while all "new" give green. Expectations swapped in the "delay2" prgs?
