How can i open an IBM 6713 typewriter?
The IBM 6713 is known as the "Electronic Typewriter" first generation. The cover latches on that machine are quite stiff, and more difficult to see than selectrics, or others.
If you open the top cover, look between the machine frame and the inside of the cover at the bottom. You will see a gold rail on each side of the machine with a tab folded over where a large screwdriver can be placed in the slot. Put a large screwdriver in that slot, and then slide that tab (I believe it's) pull it forward toward yourself. It will be VERY tight and you will need to use significant amounts of force to get it to move. You should repeat this process for the other side. You're not likely to damage anything as long as you are in that latch rail, which is gold in color.
If the machine is not working, and you have some dream of fixing it; best of luck to you. The machine's rightful place in history is to drop it off a cliff. By this age, the power module pulleys will be broken resulting in a carrier that won't move. To replace those requires both new parts, training, and a *lot* of skill. Nobody, including myself, that was trained to fix those would touch one of them today, if you could get the part.
The power module is a two-speed bi-directional transmission affair that provided the motion from a uni-directional motor to the screw that the carrier follows. They are notoriously unreliable, and once IBM declared the generation at end of life, and refused to look at them, that was lights out for the IBM Electronic Typewriter models 50, 60, and 75 only.
The replacement models are 65, 85, and 95, and are not bad machines at all, but still few if any would agree to work on one. All were complicated, and the first generation unacceptably unreliable.
