A quick update -- I ran the ZTCD diagnostics and they do fail, despite my
recollection (this is what I get for not taking notes at the end of
yesterday, and yesterday seems so far away now...). The first test (a
forward WALL, followed by an RALL of a single block) fails with the
following spew (for example):
BLKRQ 000310 DATA ERR WORD 00054. S/B 176376 WAS 104106
Based on a reading of the fiche listing (which is a slightly newer revision
of the binary I have) I believe S/B is the expected data and "WAS" is the
read-back data for a given word. Since one appears to be the obverse
complement of the other, it looks like the obverse complement logic is
running when it shouldn't be...
Yes, those two patterns are indeed obverse complement. Word 0054? That's odd, if
it's doing this wrong for a word in the middle of the buffer. Can you have it halt on
fail so you can examine the buffer?
