PARC invented so many things, it’s hard to list…<br>
Ethernet, Laser printers, GUI & Windowing System, Object Oriented (? good ?), what became ’the PC'<br></font><br></blockquote><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"><font color="#0000ff">What we call laser printers (xerography-based printers driven by a computer) pre-dates PARC. The XGP took a Xerox long-distance fax (LDX) machine and connected it to the computer using the 200 bpi Hershey fonts. This is a picture from the late 1960s of the LDX:</font></span></div><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"><img src="cid:ii_ln7ohiph0" alt="XeroxLong Distance Xerography LDX.jpg" width="400" height="540"><br></span></div><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"><br></span></div><div><font color="#0000ff"><span class="gmail_default" style="font-family:arial,helvetica,sans-serif">The CMU one was first online (shortly) </span><span class="gmail_default" style="font-family:arial,helvetica,sans-serif">followed by MIT and then Stanford about 6 mons later.</span></font></div><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"><font color="#0000ff">Here are two of my favorite pics: loading TP into the XGP:</font></span></div><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"><br></span></div><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"><img src="cid:ii_ln7ojwxn1" alt="Load TP into XGP.jpg" width="562" height="360"><br></span></div><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"><font color="#0000ff">and the output =- small diplomas:</font></span></div><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"><img src="cid:ii_ln7okjjq2" alt="CMU Diplomas on toilet paper with sig.jpg" width="359" height="562"><br></span></div><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"><br></span></div><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"><font color="#0000ff">Fun story about the PARC/Adobe's late Charles Geschke. His Ph.D. thesis was the first to be printed on it. CMU's Library initially rejected it and would not grant him his diploma, because they wanted the hand-typed masters for their archives. It took many months and lots of pleas from folks in the CS Department to get him an exception - trying to explain they the library had the master already.</font></span></div></div></div><div hspace="streak-pt-mark" style="max-height:1px"><img alt="" style="width:0px;max-height:0px;overflow:hidden" src="https://mailfoogae.appspot.com/t?sender=aY2xlbWNAY2NjLmNvbQ%3D%3D&type=zerocontent&guid=c53c271a-cfe7-4c08-b369-56e8b9d44b55"><font color="#ffffff" size="1">ᐧ</font></div>
