Vintage PDP8S - Bob Rosenbloom has his new (50 year old) Digital Equipment Corporation minicomputer operational

Great news - Bob Rosenbloom successfully restores his PDP8S minicomputer to working condition. This is the minicomputer from the "Bugbook Historical Microcomputer Museum".  We visited Bob just last week in Santa Cruz , California and he had started the process of restoring the PDP8S. He first removed every card , cleaned the card and contacts, then checked every transistor and diode. He did find a few transistors and diodes bad. This sure saved a lot of diagnostic time. See the video below for Bob's description of the restoration and operating PDP8S.

Display area in Bob's computer corner - this is how he uses his airplane hanger. I don't know just where the airplane is but the computers are in here.

9 containers full of collectable computers and electronic memorabilia.

The visit to see Bob's collection was really interesting. He has a great collection of very interesting historical computers and other electronic equipment. He also lives next to a private air strip he uses with his airplane. The Redwood trees around his property are very large compared to our Pine and Firs trees here in Virginia. He lives in an interesting area of the Santa Cruz Mountains and we enjoyed the rural experience.

Vintage Computers- PDP8s & PDP8 Minicomputers have a new home with Bob Rosenbloom

LR Bob & Dave

Bob Rosenbloom came in early this morning by plane from Santa Cruz, California and arrived  at the "Bugbook Historical Microcomputer Museum" warehouse ready to load up by 10:30 AM. Our loading crew arrived about 10 minutes later. Bob's rented truck was loaded with the PDP8S, PDP8 minicomputer and the Systron Donner Analog Computer in about 1 hour - the loading really went smoothly as the Analog computer weighs in at 800 pounds - we used a forklift to get this on the truck. Bob also loaded an ASR33 Teletype for the PDP computers.   The PDP8S was rather small and light weight - it went into the  passenger seat of the truck for a cushy ride to California.
Bob was treated to a Virginia Lunch at our house by my wife Gaynell. Bob and I then did a 2 hour tour of our area that included the "Bugbook Historical Microcomputer Museum" and our "Chantilly Festival Farm" . It was about 3:30 PM however for Bob's California time it was only 12:30 and he took to the road to get a good start on his 2700 mile journey to Sana Cruz, CA.

Update - My wife and I visited Bob Rosenbloom and Lyle Beckley - in October 2013 after they had purchased computers from  our collection - great visit we  also visited the Computer History Museum while in CA.

   Bob arrived today and here is a few words about the journey in his own words, 8-9-13

 Easy fellows, this is important cargo.

 On the truck - easy with the right equipment.

WOW it was great to load these computers for a new home and  Bob is sure excited to have them for his collection. Bob really likes the vintage minicomputers and other large antique computer memorabilia.  I like all this also however I am working more with the historical Microcomputers. All of our staff are delighted to see these computers go to a new home where they will be treated very special.
