The main difference is that southeastern Iberian script doesn't show the vocalic redundancy of the syllabic signs.

The northeastern script was very nearly deciphered in 1922 by Manuel Gómez-Moreno Martínez, who systematically linked the syllabic signs with the occlusive values.

Linear B has roughly 200 signs, divided into syllabic signs with phonetic values and ideograms with semantic values.

The grid developed during decipherment by Michael Ventris and John Chadwick of phonetic values for syllabic signs is shown below.

Over time, many syllabic signs were developed.

It is most often classified as a logographic or (more properly) a logosyllabic writing system, in which syllabic signs play a significant role.

The Mycenaean language is preserved in Linear B writing, which consists of about 200 syllabic signs and logograms.

In essence, a limited number of syllabic signs must represent a much greater number of produced syllables, better represented phonetically by the letters of an alphabet.

It also contained syllabic signs and logograms.

The system consists of a combination of logophonetic, consonantal alphabetic and syllabic signs.
