Back in the US! In the city that never sleeps!

Domenica 30 Aprile 2023, 03:46

Well, it seems that blogging is definitely an outdated way to express oneself on the web nowadays. Additionally, I rarely write anything here anymore. Perhaps I feel that I have less and less interesting things to say (or to type). By the way, I am currently in New York City! 😊

 

VIC-20 The friendly computer

Domenica 15 Agosto 2021, 17:26

2021-08/vespacommodore.jpgIt’s been a long while since my last post on this blog. This boring era made of real time social things and dynamic digital networks full of contacts and followers (my optimal number of social interactions is far below the Dunbar’s number!) is eroding the time once devoted to write something more well-finished.

Anyway, a new post in the end, 5 years from my last one here. I will write again about retro-nerd-things and restorations I usually make during holidays, when I am far from everyday duties.

This year, also due to the home relocation we started months ago and which is still unfinished, I dedicated my time to fix and restore my first computer, yes the first one I have ever, ever had in my hands. All of my so long forgotten knowledge about it is deeply buried in the mist of my childhood memories, back to early 1984 if I am correct.

In that year Piaggio (my father then worked for them in a big bike dealership in Bologna) launched an ad campaign focused on a Commodore VIC-20 given away as a gift for customers purchasing a Vespa PX125. I can clearly remember those coloured boxes lying on the shelves, in the customer care area of BeMotor (the dealership’s name, today oriented in selling cars only).

Cray-1 - The home supercomputer

Giovedì 01 Dicembre 2016, 20:50

Cray-1AIt took me almost a year to complete the Cray-1 project during my spare time. When I decided to build a physical copy of the first supercomputer ever, as faithful as possible, I found on the web a lot of inspiring examples (just like this one by Chris Fenton). In 1975 the 80 MHz Cray-1A was announced. Excitement was so high that a bidding war for the first machine broke out between Lawrence Livermore National Laboratory and Los Alamos National Laboratory, the latter eventually winning and receiving serial number 001 in 1976 for a six-month trial. Since then, the Cray-1 supercomputer reigned as the world’s fastest from 1976 to 1982 (source).

My personal 1:8 Cray-1A was made laser cutting some plexiglass sheets after a careful drafting process of the main vertical framework, which originally hosted over 60 miles of wire with no segment longer than 3 inches, to minimize signal delays. Amazing! My Cray-1A is equipped with a Rasperry Pi 2 board (out of 12 possible parallel slots) running a customized Os: a dedicated I2C controller drives a 16x2 characters LCD blue display while wi-fi and bluetooth interfaces guarantee wireless connections.

The weird 3D tourist

Venerdì 26 Agosto 2016, 18:40

Paris from the Arc de Triomphe (S. Garagnani)
 

As part of my job and research work, I'm always into the digital representation of the built environment, even when off-duty. It's mostly a state-of-mind attitude, I suppose. That's probably why I cannot behave like ordinary visitors especially when I am a tourist on holidays for the first time in Paris!

 

My Dinky Toys' Space 1999 Eagle restoration project

Domenica 29 Maggio 2016, 22:52

Eagle After some very busy weeks, I managed to apply the decals I ordered last month on eBay to complete my Dinky Toys' Space 1999 eagle. Since I found in UK another Eagle in very bad conditions, I decided to restore it as well, bringing to a new life another spaceship, this time in its Rescue livery. So, after Episode I, Episode II and Episode III, it's time to make the story short, presenting the final results of my efforts. My Eagles are now ready to take off from Moonbase Alpha...
Paul Morrow: Alpha to Eagle One, come in One. Alpha to Eagle One, come in One. 
Cmdr. John Koenig: Eagle One to base, we copy. Paul, we're returning to Alpha. 

Let's go straight to the final Episode!
