I’m delighted with this gift I received for speaking at the @tnmoc Econet LAN Party event. Wonderful!
IN APPRECIATION OF YOUR CONTRIBUTION The National Museum of Computing thanks you for your valued contribution. Your support helps preserve and share the history of computing for generations to come.

WITH THANKS FROM THE NATIONAL MUSEUM OF COMPUTING This frame was presented to ROBERT SMALLSHIRE in recognition of their valued contribution. Enclosed is a representation of 5-hole teleprinter tape spelling "THANK YOU" in Baudot-Murray code - a historic encoding system used in teleprinters from the early 1900s. The pattern was digitally recreated from authentic paper tape punched on the Museum's Elliott 803 computer. This same format could be read by Colossus, Heath Robinson, and many wartime and postwar machines. Now preserved in laser-cut acrylic, it offers a permanent, physical connection to the Museum and the technologies and knowledge you help us celebrate and preserve. Thank you.

On this Day! In 1941 The Zuse Z3 was completed by Konrad Zuse in Berlin. I's the world’s first working, program-controlled, and fully automatic digital computer. It was a Turing-complete machine and implemented essential components of modern computing . #ZuseZ3 #TuringComplete

On this day in 1979, the world of business changed with the release of VisiCalc! Before Excel or Google Sheets, the "Visible Calculator" for the Apple II was created by Dan Bricklin & Bob Frankston. It was the first electronic spreadsheet. #VisiCalc #ComputingHistory #OnThisDay
