Ericsson Alfaskop SYSIPL file

SYSIPL carries the autologon table: what each display unit loads without being asked, which is usually the best single clue to what a volume was for.

The entries sit in 128 byte slots, one per unit, and most are:

Off

Len

Field

0

1

0x00

1

1

0x0b, the length of what follows

2

8

Logon name, looked up in the volume’s logon table

10

3

Load map number

Other forms seem to exist, see for instance ⟦c0e6de830⟧ and ⟦7f560e188⟧.

Not every slot is filled and the used ones are not always the first, so they are found by signature rather than by index. A volume with no entry at all comes up at the operator’s function menu instead.

Usage

from autoarchaeologist.vendor.ericsson.alfaskop import sysipl
