Letter from Paul G. Allen
It is possible that no other technology on earth has so continually renewed itself as computer technology. Advances in this field arrive in such swift succession that even the software and hardware of a few seasons ago are considered obsolete. The decades-old computers and software in this collection, therefore, are truly worthy of our preservation and study – both for the cutting-edge innovations of their day as well as for their historical significance. 

The Living Computer Museum also fulfills my hope that the achievements of early computer engineers aren't lost to time. I wanted to provide a website and repository that recognized the efforts of those creative engineers who made some of the early breakthroughs in interactive computing that changed the world. 

I hope you enjoy learning more about these remarkable machines. I certainly had a ball using them in their heyday – from the late 1960s to the early 1980s. During that period almost all Microsoft development was done on these platforms. 

Calendar of Events
Bits & Bytes - CANCELED
August 27th, 10 am - 5 pm

LCM has undertaken some large projects this summer, most noticeably our first floor expansion, which, if you’ve dropped by recently you’ve probably noticed.

In an effort to keep everything on track, we will be canceling our event, Bits and Bytes, for Saturday, August 27th.

Make sure to check back with us later this year when we will be announcing our opening for the first floor this fall!
Movie Night: "Zero Days..."
September 1st, 6:15 pm - 7:05 pm

Join us for Zero Days: White Hat and Black Hat Hackers!

Secret backdoors, that do not have a digital lock yet, are being traded at astronomical amounts. In the cyber world trade, where there are no rules, you are in luck with “white-hat” hackers, who guard your online security. But their opponents, the “black-hat” hackers, have an interest in an unsecure internet, and sell security leaks to the highest bidder. Who are these black and white wizards, who fight for the holy grail of hackers: zero days?
