1) The base memory released by the extended memory can be configured as extension memory and
used to store texts and DBs
As the price differences between the different memory chips are very small, we rec-
ommend the use of the following types:

1) Where RAM components not approved by Saia are used, there is a risk of losing data
2) The use of EPROMs is obsolete; use Flash EPROM instead
3) Flash EPROM is supported from firmware version 002 only
4) To hold the configuration, a portion of memory is lost, so for this chip,112 Kbytes rather than 128 are available to
the user
