fx-720P

fx-795P

fx-720P

 Model fx-720P (i think this is the old one): RAM-Card storage in a flip case (the upper one shown above), very hard to use

Model fx-720P(F): RAM Card storage in a bay with separate flap (the lower one shown above).

The model number is shown on top and bottom of the computer (see "fx-720P (F)" on bottom in the pic). The manual is different in the RAM-Card usage part.

Exact production dates unknown.

The fx-720P bought via E-Bay, the fx-720P(F) bought about 03/1989 by myself 

fx-795P

The differences of the fx-795P are also very clear to see: The older one (the upper one shown above, in fact a fx-790) use the RAM-Pack-System, the newer one (the lower one shown above, a real fx-795) has build-in memory and is not expendable.

The model number on top and bottom of the computer shows no clear differences. The manual still shows the RAM-pack, but there are no handling instructions for it for the newer one.

Exact production dates unknown.

Older fx bought via E-Bay, the newer bought 08/2002 at Karstadt.de, Germany
