Guest speaker: Brian Utley

Brian Utley was the 1130's Project Manager during its development and introduction. He also managed the development of several other significant systems, including the System/7, the System/38, and the Series/1, and he managed the IBM PC's introduction to Europe. Over the course of his career he was Director of Small/Medium Systems Architecture, General Manager of IBM Biomedical Systems, General Manager of IBM Boca Raton, and founding member and Director of the Boca Raton laboratory (where the IBM PC was developed). He spontaneously offered to speak at this year's "11/30" party, and it was a great, entertaining, illuminating presentation. Of course, many 1130 fans couldn't make it to Mountain View, so we recorded his presentation and now make it available as a series of MP3s. Start listening by clicking on the first MP3 link below, or simply download this 13MB ZIP file of all of them, 55 minutes total, ready to burn onto a CD! (Set the inter-track gap to 0 seconds if you can.)

When we transcribe the talk and Brian Utley has had a chance to proofread the transcript, we'll post it here as well.

Stuttgart 1130 demo via webcam

The other treat of the day was a live demonstration of another 1130 fan group's system in Stuttgart, via webcam. We have screenshots of the demo and will put some up “soon.”
