Identification plate on Burroughs TD700 Self-Scan early gas plasma display screen with main control unit and keyboard. Design Level (DL) 4 c1973.
Although the control unit identity plate is stamped for 240 volts, the power supply test points for 5.1v, 12v, -12v, 30v, and -250v were all up to required values on 110 volts AC supply from the variac..!
My very first computer ever was a TRS-80 Model I. It was cookin' with the Level II Basic and 16k upgrade! Woot!
As such, I've always had a soft spot in my retro-computer heart for the TRS-80 line. Yes, they were pretty much the worst of the bunch for graphics (what, a "hires" pixel being a white square 1/8th inch square isn't GOOD enough for you?!?) even compared to the other dino's back then, but just like your first car, first girlfriend, etc....you never quite forget. :)
So, I never liked the fact that the "war posters" in those days called 'em "Trash eighties."
But, now of course, like all things retro, one must embrace the bad as well as the good...so, I took one of my old Model III's from the garage and converted into my very own "TRaSh-80."
(I really should put the real drives back in, just to add to the illusion, but they're too heavy and make the garbage can fall over. When I find a bigger can to mount it on, maybe...)
This is my Atari ST on Twitter. Its connecting via my Linux server over a serial terminal session. Its kinda cheating, but I dont have ethernet for my ST.

I picked up a silver Game Boy Advance SP at a carboot sale for £4, but it was very scratched. So I bought a replacement case off eBay for £6.
The Game Boy now looks brand new.

I have replaced the original ROM in this 464 with the same ROM you would find in the 6128. This gives you a few extra BASIC commands.

Work in progress on the HEX keypad. The generic 6425 push buttons & keytops get BECC self-adhesive vinyl lettering used by modellers. The key switches are mounted on conventional copper strip veroboard, with the IC sockets installed on Protoboard-3U.

L'8 luglio 2015 è stato presentato ufficialmente a Highgate, Londra, la nuova console di videogiochi ZX Vega. Basato sull'architettura del Sinclair ZX Spectrum, il Vega è sviluppato e prodotto dalla Retro Computers Ltd (www.zxvega.co.uk), un'azienda fondata da Clive Sinclair, Chris Smith, David Levy e Paul Andrews ed è stato finanziato attraverso una campagna su Indiegogo che ha raccolto circa 150.000 sterline, il 50% in più del traguardo inizialmente fissato. Io sono stato invitato all'evento, unico italiano presente, in quanto nella dotazione iniziale di 1.000 giochi compare anche il mio Cousin Horace, uscito nell'ottobre 2014 (per saperne di più: www.alessandrogrussu.it/diario-2014-10-01.html).
Nella foto: il picnic a Parliament Hill, gentilmente offerto dagli organizzatori - comprendente persino una bottiglia di champagne a testa! - conclude degnamente l'evento. Il monumento è la Stone of Free Speech (Pietra della Libertà di Parola).

On the 8th of July, 2015, the ZX Vega, a new videogame console, was officially presented in Highgate, London. Based on the Sinclair ZX Spectrum architecture, the Vega is developed and produced by Retro Computers Ltd (www.zxvega.co.uk), a company founded by Clive Sinclair, Chris Smith, David Levy and Paul Andrews, and it was funded through an Indiegogo campaign which raised about £150,000, 50% more than the initially set target. I was invited, the only one from Italy, because my Cousin Horace, released in October 2014, has been included in the initial set of 1,000 games coming with the console (more on this can be found at: www.alessandrogrussu.it/diario-2014-10-01.html).
Photo: the picnic at Parliament Hill, kindly offered by the organizing team - it even included a champagne bottle for each one of us! - was a worthy end to the event. The moument is the Stone of Free Speech.
Picked this up today from a car boot sale. Came with one controller, RF cable (YUK! - Must make RGB scart cable ASAP!), power supply and 5 games.
