The Colour Maximite is a small and versatile single chip computer running a full featured BASIC interpreter with 128K of working memory and eight colours on a VGA monitor.

It will work with a standard PC keyboard and because the Maximite has its own built in SD memory card and BASIC language you need nothing more to start writing and running BASIC programs.

When HP designed the 3000 series 30 using the processor from the HP 300 they had to make it compatible with previous HP 3000s and the HP MPE OS they ran. This entailed breaking down the MPE OS into 2 parts, those that were entirely software dependant, and those that were hardware dependant, and then writing the microcode to handle the hardware dependent part of the OS. Like the HP 300, the HP 3000 architecture is stack based, with the PCU chip holding 2 Top of Stack registers for fast access to the (off chip) stacks. The Series 30/33 have a total of 214 instructions while the HP 300 uses just under 200 instructions. Instructions are 32 bits long and typically

The exact same ICs are used for the HP 300 as for the Series 30/33 with 'one pin of each chip tied to a different voltage level.' Exactly what pin that is and what voltage is not said. Looking at the handdrawn schematic of the Series 33 does show the /DIS pin pulled high (12V) on both the RALU/RASS chips, though what that pin is for is unknown.

Never have I wanted a computer as much as the Sony VAIO P.

Never have I been so wrong.

Sony introduced the VAIO P at CES 2009, the height of the netbook boom, and its stunning design soared high above all competitors racing to the bottom. Look at your laptop; now imagine that the bottom half was nothing but the keyboard, and the top half was dominated by an ultrawide high-resolution screen. That's the VAIO P. It is screamingly beautiful even today.

Did you buy the new MacBook or MacBook Pro? Maybe the Google Pixel? You're about to enter a world of confusion thanks to those new USB-C" ports. See, that simple-looking port hides a world of complexity, and the (thankful) backward-compatibility uses different kinds of cables for different tasks. Shoppers have to be very careful to buy exactly the right cable for their devices!

The pinout of that 68K Game Shifter, however, does not match the Shifter IC in any of the Atari ST computers. But incidentally, the never released Atari Panther was to be a Motorola 68000 based game console. Furthermore, the Panther prototype board features a chip conspicuously marked 4118!

So after the cancellation of the Panther development in 1991, I may well be first person for 25 years to be looking at the design of its shifter chip.

But now, seven years later, Lenovo is introducing a new take on the tablet computer. No, Lenovo didn't make a Courier, but its new Yoga Book might inspire the same reactions. It's about the size and shape of a hardcover children's book, has two panels attached by a hinge, and can be used with your fingers or with its included pen. It even does some tricks with the pen that we've never seen before, like letting you write with real ink and have it all digitized. Lenovo didn't set out to build just another tablet with the Yoga Book - it wanted to make something that was better for getting work done than what is already out there.

But in the process, it made a computer that's both futuristic and relatable at the same time, just like the original Courier concept. I wanted to use the Yoga Book from the first time I laid eyes on it, and if you're anything like me, you will, too. And unlike the Courier, you will actually be able to buy the Yoga Book.

SoftBank is nearing a deal to acquire ARM Holdings, the British semiconductor company, said two people briefed on the matter who asked not to be named discussing private information.

The deal would be the first large-scale, cross-border transaction in Britain since it voted to exit the European Union last month. ARM had been seen as a safe haven from the volatility surrounding “Brexit” because its chip technology is used in mobile phones all over the world, with limited revenue derived from Britain.

I worked for Lexra, a scrappy CPU company, now out of business. The Lexra story is filled with lessons about the business of selling microprocessors and semiconductor intellectual property. I have found many incorrect statements published about Lexra. I hope to set the record straight.

Alan Kay recently loaned his 1970's Xerox Alto to Y Combinator and I'm helping with the restoration of this legendary system. The Alto was the first computer designed around a graphical user interface and introduced Ethernet and the laser printer to the world. The Alto also was one of the first object-oriented systems, supporting the Mesa and Smalltalk languages. The Alto was truly revolutionary when it came out in 1973, designed by computer pioneer Chuck Thacker.

This is a happy story about the power of global communication and manufacturing resources in today's world. If you've been reading this blog for any length of time, then you've certainly heard me whine and moan about how impossible it is to find the obscure DB-19 disk connector used on vintage Macintosh and Apple II computers (and some NeXT and Atari computers too). Nobody has made these connectors for decades.

But just as I was getting discouraged, good luck arrived in the form of several other people who were also interested in DB-19 connectors! The NeXT and Atari communities were also suffering from a DB-19 shortage, as well as others in the vintage Apple community, and at least one electronics parts supplier too. After more than a year of struggling to make manufacturing work economically, I was able to arrange a "group buy" in less than a week. Now let's do this thing!

One of the tricks you can do on the C64 involves manipulating the video chip into reading the graphics data at an offset from where it's usually located. This allows you to scroll the display horizontally, and the trick is called VSP for Variable Screen Position. However, some machines crash when you attempt this, and the reason for that has always been a mystery. Not anymore.

This is a Compaq LTE 5280 laptop from the early 1990s, running a bespoke CA card. In 2016, McLaren Automotive - one of the most high-tech car and technology companies on the planet - still uses it and its DOS-based software to service the remaining hundred McLaren F1s out there, each valued at $10 million or more.

There is something special happening in a generic office park in an uninspiring suburb near Fort Lauderdale, Florida. Inside, amid the low gray cubicles, clustered desks, and empty swivel chairs, an impossible 8-inch robot drone from an alien planet hovers chest-high in front of a row of potted plants. It is steampunk-cute, minutely detailed. I can walk around it and examine it from any angle. I can squat to look at its ornate underside. Bending closer, I bring my face to within inches of it to inspect its tiny pipes and protruding armatures. I can see polishing swirls where the metallic surface was “milled.” When I raise a hand, it approaches and extends a glowing appendage to touch my fingertip. I reach out and move it around. I step back across the room to view it from afar. All the while it hums and slowly rotates above a desk. It looks as real as the lamps and computer monitors around it. It’s not. I’m seeing all this through a synthetic-reality headset. Intellectually, I know this drone is an elaborate simulation, but as far as my eyes are concerned it’s really there, in that ordinary office. It is a virtual object, but there is no evidence of pixels or digital artifacts in its three-dimensional fullness. If I reposition my head just so, I can get the virtual drone to line up in front of a bright office lamp and perceive that it is faintly transparent, but that hint does not impede the strong sense of it being present. This, of course, is one of the great promises of artificial reality - either you get teleported to magical places or magical things get teleported to you. And in this prototype headset, created by the much speculated about, ultrasecretive company called Magic Leap, this alien drone certainly does seem to be transported to this office in Florida - and its reality is stronger than I thought possible.
