Limited edition early version of this album release, which included a bonus 12" described on a sticker on the sleeve as "limited ambient 12". Side A of the 12" plays at 45rpm, side B at 33rpm.

There are several mismatches between the cover and the labels on some track titles and times:

Covers reads:

A1 Sea Serpent (5:20)
A2 Splitting Atoms (6:20)
B1 Natural Science (9:30)
B2 Taking Sides (6;20)
C1 Mauve Violin (5:30)
C2 Time To Time (6:08)
D1 Secret Gardens (6:25)
D2 Colonian Space Unexplored (6:00)

Cover states A2, C2 and D2 are co-produced by Alan Sage, labels only credit him on A2.

Also the track list on side B of PF011X is printed incorrectly, below is the order they appear.
