Thirty seven groups of eight bytes, one group per object (including "nothing at all"). The values are:

Offset	Effect
0	Weight / flags
1	Flags
2	Unused
3	Read text (index)
4	Attribute flags
5	Terrain interaction parameter
6	Attribute
7	Graphic index in lookup table at 55950

Byte 0: Objects can have weight values from 0 - 15 inclusive. Weight is defined by the first four bits of the first data field. The remaining bits are for object flags:

Bit	Effect
0	Weight
1	Weight
2	Weight
3	Weight
4	Drop-status (set means cannot be dropped)
5	Can-be-read
6	Can-be-blown (see trivia)
7	Is-breakable

Byte 1:

Use status is comprised of bitwise flags:

Bit	Effect
0	Unused
1	Unused
2	Unused
3	Can-be-worn
4	Unused
5	Unused
6	Unused
7	Unused

Byte 4:

Flags which each specify whether the object's attribute applies to one of the object's four constituent character blocks. This value also effectively specifies which of the four possible character blocks are occupied by the object (i.e. the object's size in characters). This is relevant to the application of the object's terrain interaction parameter.

Bit	Effect
0	Paint-top-left
1	Paint-top-right
2	Paint-bottom-left
3	Paint-bottom-right
4	Unused
5	Unused
6	Unused
7	Unused
