POS System

As IBM had put power also into the field of POS very well, also in
PS/55 of MCA,
the adapter existed.
I want to explain a multi-station generation's POS system.
4680 Store System
4692 POS Workstation
4680 Store System
This is the system which combined the POS terminal and
the multi-station as
a controller.
However, it is not the usual multi-station. It is the
machine of exclusive use of
the name of a 4681 Store controler.
The upper figure is a composition figure
of a system.
It is the features to have loop type topology and that
there are two controlers
and backup is taken automatically.
A network is called a store loop. Speed is 38.4KBPS.
As for between Controlers, synchronous processing is always
taken.
Even if an obstacle occurs in one set, it can work normally
at one set.
At the time of recovery, a synchronization is automatically
restarted by
automatic recovery processing.
In addition, if PS/55 are connectable as a terminal, it
has become.
However, it is not known what kind of adapter and software
were required for.
4681 Store controler
Appearance is a multi-station as it is. It is thought
that 5560 is probably
a prototype.

A multi-item input keyboard is a keyboard which can be
inputted now by
one-touch by registering a brand name and a unit price
into a touch-type
keyboard.

4692 POS Workstation
Although it can consider only by seeing a photograph at least
in the POS terminal
where a screen is large,
it is not the machine of only that as the name of a "workstation".
It is the POS terminal which can be used also as a personal
computer in fact.
Since CPU is not known, it does not turn out that the personal
computer used as
a base says which model it is.
In spite of being a screen of 9 inches, it seems to be that
a 24-dot display is
uncanny.
When using it as a personal computer, the cover put upwards
stuck so that it might
not waver by the keyboard.
However, since a keyboard layout completely differs from usual,
troubles are likely
to be suffered when using it.
Since various options are attached, it is not troubled by the
time of use as a usual
personal computer.
The thing with many options of a communication system thinks
that it is a reason
that it is a POS terminal.
If the photograph which attached the option is seen, it will
be convinced that it is
the personal computer which can be used as a POS terminal.
