Sony’s First Pc | Hackaday

In 1982, desktop computer systems had been coming into their very own, and no clear leaders had emerged. But everybody knew they needed a chunk of the motion. This led to, amongst different issues, Sony’s SMC-70, which, frankly, for 1982, was a handsome, if not oddball, machine. [Tech Tangents] exhibits the machine off in a latest video.

From the entrance, the pc seems more-or-less like all the things else. But as you progress backward, you’ll be able to see this pc wasn’t one other typical entry into the market. One of the issues that was the hallmark of profitable corporate affairs computer systems of the day was expandability. The earlier Altair had the later-titled S100 bus. The IBM PC had the ISA bus. But in each circumstances, you needed to open the field to plug and unplug playing cards.

The SMC-70, although, had a really distinctive system. Instead of boards, customers would line up modules and stab them with what amounted to skewers to mechanically safe the stack of modules. You may stack some modules vertically or horizontally utilizing ribbon cables or exterior cables. This specific field wanted some energy provide work, and a 3D printer lets it look primarily inventory.

Computing-wise, the SMC-70 was fairly typical. A CP/M machine with a 4 MHz Z-80 wasn’t novel then, though few CP/M programs had 3.5-inch floppies. What set the Sony aside was its 16-color graphics system, which was properly forward of its time. It even had some sound functionality.

It additionally had a module that provided fairly a little bit of video output functionality, which shouldn’t be shocking given Sony’s different product strains. There was, apparently, an 8086 module that ultimately turned accessible, but it surely was late and didn’t run MS-DOS (however may run CP/M-86).

A couple of good options didn’t catch on. A devoted pink assist button on the keyboard was a pleasant thought, for instance. There was even a RAM disk mode, which was nice in the event you didn’t undergo energy outages.

Of course, Sony made many more computers. If you wish to play with a CP/M machine, you most likely may get a digital one up in a few minutes.
