Macintosh Portable: PDS Manual Correction

* To indicate that problem has been corrected in the manual


Is there a problem with figure 13-5 (a diagram of the Macintosh Portable
68000 Direct Slot) on page 280 of "Designing Cards and Drivers for the
Macintosh Family"? In a real Macintosh Portable, the PDS connector
is soldered on the board rotated 180 degrees.

I've heard the connector should be soldered as described in the book, which
is the official way. Which one is correct, the book or the Macintosh?

The manuals ("Guide to the Macintosh Family Hardware", second and
third editions, and "Designing Cards and Drivers for the Macintosh
Family", second edition) are in error. The signals and signal
descriptions are correct, but the key for the slot is off by 180
degrees (that is, columns A and C should be swapped, as should be
rows 1 and 32).

The manual "Designing Cards and Drivers for the Macintosh Family",
third edition, has been updated and the Macintosh Portable PDS diagram
has been corrected.
