 We invite you to familiarize yourself with
with a full description of the program BIG
HELP, which was presented
in the first issue ofZX-DIGEST'a.

The programBIG HELPrepresents
is a collection of descriptions of in-
terral circuits.               
 Immediately after loading you
you fall into a menu consisting of
the following items:

 Selecting a menu item is carried out
is done using the arrow cursor,
which can be controlled by the key-
miQ,A,O, R. Space - active
selection.                   
                                
 Let's start describing the menu options in
the order in which they are distributed

HELP - output of a certificate of destination
purpose and capabilities of the program
we.                             
                                
                                
SEARCH - you will be asked to enter the field
the name of the integrated circuit,
for example, 555AGCH. Search is underway
on disk. After finishing the search
a message appears indicating that it has been found
Is there a microcircuit?  If she doesn't
found, try to enter another
This name.                   
 SERIES  - display information about the series
ria to which the current belongs
current microcircuit (implementation type
functions performed, typical parameters
parameters (delay time, consumption
power output, voltage
tania, etc.), in which buildings
and with what pin arrangement
released). In parentheses indicate
The name of the Western analogue is given.
