Sony Hit Bit 10P

Tonight I'm going to speak of my first MSX computer. I just waited too long to collect it, but it was worth the waiting. This is the Sony Hit Bit 10P.
MSX is an acronym for Machines with Software eXchangeability, and was the first attempt to standardize the home computer. There is no coincidence that a such Microsoft was involved in. 🙂

Sony Hit Bit 10-P

This standard, defined and published in the early 80s, passed almost unnoticed in both the old continent and the U.S., and found a strong response in Japan and South America, particularly in Brazil. Over the years, was further expanded, landing the definition of MSX-2

The machine that I own, expensively purchased through e-bay, was produced by Sony that, Like many Japanese factories, provided a major contribution to the MSX machines.

Japanese model

Hit Bit serie was the Sony entry-level production, and was distributed in two colors: a fire-red one, dedicated to the Japanese market, and a black version, targeting foreign markets. The final letter of the code identifies the country in which the serie was marketed. The specimens were Spanish codename ending with S, the ones in Germany with D, the Portuguese ones (or Polish?) as mine, with the letter P.

To obtain the approval of the MSX consortium, each machine had to meet certain requirements. Continue Reading

Acorn Archimedes A4000

Acorn Archimedes, the British rival of Amiga and Atari ST. People discussed a lot about it, but in Italy just a few actually had it. Finally it is mine! 🙂

It was the year 1987 and Britain's Acorn, in the wake of the good success of the BBC Master – and even before the BBC Electon – decided to participate in the technology race of the time, opposed to competitors that proposed mainly 16 bit, or hybrid ones at 16-32.
The very first model of this popular family of personal computers was called Archimedes 305, and was equipped with an ARM CPU clocked at 8MHz, fully at 32 bit (competitors was using the Motorola 680xx family of CPUs. Processors were substantially at 16 bit, with some registers using 32 bit), and with a range of video resolutions unprecedented for its time, i.e. a powerful 896×352 at 256 colors!
If the graphics was nothing short of thrilling, the audio section was even exaggerated: such as 8 independent voices, spread over two stereo channels. Continue Reading
