It’s unclear, based on this only, which machine first had an “electronic memory”.

1978: The IBM Electronic Typewriter 50 and 60 (“the first electronic typewriters”).

1977 (March): IBM Memory 100 Typewriter debuts.

1975 (January): IBM Electronic Selectric Composer launched.

1973 (April): IBM Mag Card II Typewriter announced (“Its electronic memory holds up to 8,000 characters.”).

1969: Mag Card Selectric Typewriter announced.

There is also a chronology in IBM’s IBM typewriter milestones. The IBM Memory 100 Typewriter, with a 100 page built-in action file, was introduced in 1977 The memory is capable of storing up to 50 pages of copy which can be played back in error-free form at 150 words per minute. The memory is activated whenever typists begin keyboarding and because it works in conjunction with the typewriter’s special correction system, typists can record all work at “rough draft” speed. Built into the typewriter is a memory which stores everything typed and allows the operator to recall and revise previously typed material. In 1974, the introduction of the IBM Memory Typewriter enabled typists to complete their work with a minimum of time and effort. The machine is mentioned in IBM’s The typewriter: an informal history: While for many typewriters you can find a wealth of information online these days, it’s definitely not the case with the Memory Typewriter. This makes it all the more tempting to get this machine to work! Here is an excerpt from the service manual. In short, this was one of the first word-processing machines. So what’s special about it? Well, the IBM Memory Typewriter is essentially an IBM Selectric typewriter with an important addition: the ability to record text both in solid-state memory and on a built-in magnetic tape, and to play it back. They contain an incredible amount of very useful information.

Through this group I was able to get a copy of the service and diagnostic manuals for this machine. The Golfballtypewritershop group was very helpful to get started. UPDATE: I was kindly pointed out that this shaft is the hand-cycle tool extension! So that’s a slight relief. However, there is no immediately visible damage - but I noticed two screws and a short metal rod lying at the bottom of the machine! That will need investigating. It’s typical for the soundproofing foam to disintegrate into a sort of goo in Selectrics, but there is also a lot of dust and debris in there. The bad news is that there is probably bigger fish to fry! The good news is that these parts are not necessary to the good working of the machine. There is some damage to the top cover: one part has broken off on the right side, and one is missing on the left side. It should turn on immediately after power on, like on a regular Selectric. When turning it on, the power supply fan and one light turn on, but the AC motor doesn’t. There is no doubt that the machine is in rough condition! Needless to say, it doesn’t quite work.

2 The "planar package" Condition of the machine Maybe the most impressive part is the electronic board (called the “planar package” in the IBM service manuals) in the back, with lots of IBM chips. First, just look at how it looks like under the hood! The IBM Memory Typewriter with covers off However, it appears to be a very interesting machine, as we will see. I already own several IBM typewriters in various conditions, and even an IBM Electronic Typewriter 75 (see below), but I was not familiar with the Memory Typewriter. 1 Many thanks go to the kind soul who tipped the Golfballtypewritershop group and allowed me to pick it up locally! The IBM Memory Typewriter I recently picked up an IBM Memory Typewriter that otherwise would have been scrapped.
