If bit TXT0.INV ON is a logic 1, memory block 8 of Bank 0
is used as an inventory page.This consists of two tables:
the Transmitted Page Table (TPT) and the Subtitle Page
Table (SPT); see Fig.21.
In each table, every possible combination of the page tens
and units digit, 00H to FFH, is represented by a byte,
see Fig.22. Each bit of these bytes corresponds to a
magazine number so each page number, from
100H to 8FFH, is represented by a bit in the table.
