&gt; “The original Apple II did not support lowercase letters which is kind of surprising to most people,” Hertzfeld tells Inverse, laughing. “But the designer, Wozniak, made a trade-off that blinking characters were more important than lowercase letters.”<p>Herzfeld is mistaken: Wozniak himself says the lack of lowercase had a completely different reason:<p><pre><code> So, in the end, the basic reason for no lowercase on the Apple I and Apple II was my own lack of money. Zero checking. Zero savings. </code></pre> <a href="https:&#x2F;&#x2F;www.vintagecomputing.com&#x2F;index.php&#x2F;archives&#x2F;2833&#x2F;why-the-apple-ii-didnt-support-lowercase-letters" rel="nofollow">https:&#x2F;&#x2F;www.vintagecomputing.com&#x2F;index.php&#x2F;archives&#x2F;2833&#x2F;why...</a>

The headline is completely wrong, there was no bug fixed. The blinking cursor was an invention, not a bugfix.

I was sure the blinking cursor was a staple of the mainframe folks&#x27; terminals years, maybe decades before Apple came on the scene, but I looked up some YouTube videos and the DEC VT52 (released 1974-1975) seems to have not had a blinking cursor. Its successor, the iconic VT100 did have a blinking cursor, but wasn&#x27;t released until 1978.<p>Maybe later I&#x27;ll do more research and look up other old terminal models, but I&#x27;m going to stop for now.<p>Also, I guess Apple is a little older than I thought; I always pictured the ubiquitous Apple IIe as a 1980&#x27;s machine (and I saw some in the wild well into the 1990&#x27;s). Seeing they were released in the 1970&#x27;s is pretty interesting.

Utterly buries the lede. The actual content that explains where the blinking cursor comes from is ~1 paragraph.
