Inventory page
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.
The bit for a particular page in the TPT is set when a page
header is received for that page. The bit in the SPT is set
when a page header for the page is received which has the
‘subtitle’ page header control bit (C6) set. The bit for a
particular page in the TPT is set when a page header is
received for that page. The bit in the SPT is set when a
page header for the page is received which has the
‘subtitle’ page header control bit (C6) set.
