pb_test errors - what do they mean?

[maximevince]

I have trouble getting my self-built plipbox to work.

Running pb_test (4), I get the following output:

What does it mean? How should I interpret this?

I should note that I am using a 68030-TK2 accelerator running at ~28 MHz

Even with a 68000 at 7 MHz I seem to get these errors. I am pretty confident that all connections between the DB25 and the Arduino Nano are good. Any clue how this could be happening?
I am on KS3.2.
