After years of unofficial copies of Microsoft’s 6502 BASIC floating round on the web, the software program big has launched the code below an open-source license. 6502 BASIC was one in all Microsoft’s first items of software program, tailored in 1976 by Microsoft cofounder Invoice Gates and early worker Ric Weiland to run on the 6502 CPU that powered the Apple II, Atari 2600, Nintendo Leisure…

At its Construct 2025 convention, Microsoft open-sourced numerous apps and instruments, together with a brand new command-line textual content editor for Home windows known as Edit. Open supply software program might not earn the corporate direct income, however it might function a type of market analysis — and a funnel to paid purposes and providers. By contributing to the open-source group,…

Polygon open-sources its Web3 ID solution

Polygon Labs announced that it has open-sourced its Web3 ID solution, as indicated in a blog post from the company on March 1.

Polygon initially announced the suite of tools in March 2022 and released it over course of the year. The toolset allows developers to leverage zero-knowledge proofs (or zk-proofs) to manage user credentials and identity in a private manner.

Though the toolset was previously available in a more limited way, today’s open-source release makes the suite “fully self-service,” according to Polygon. As of today, anyone who uses the toolset can act as an issuer or holder of Web3 identities.

Notably, the toolset allows developers to use off-chain data (such as government IDs, driver’s licenses, and similar documents) for on-chain verification.

This means that Polygon’s ID tools will be useful for a wider variety of organizations and applicable in a greater number of circumstances. Polygon highlighted the fact that its ID toolset can be applied in KYC verification, e-commerce, passwordless login, portable game registrations, undercollateralized lending, and DAO administration.

The company also noted that the public release introduces four new tools aimed at ID verifiers, ID issuers, wallet builders, and developers respectively.

Polygon named nineteen projects — including the popular blockchain game The Sandbox — that are already making use of its ID toolset.

Several other crypto-related projects are working on separate decentralized identity toolkits. Those efforts include Jack Dorsey’s “Web5” project, Microsoft’s ION ID system for Bitcoin, and Circle’s Verite ID system for Ethereum.

When I read that Microsoft released open-sources GW-BASIC, I couldn’t resist to take a look at the code on GitHub. I spent my childhood to play with GW-BASIC and Clipper (do you remember that?)

GW-Basic open source

These sources, as clearly stated in the repo’s readme, are the 8088 assembly language sources from 10th Feb 1983, and are being open-sourced for historical reference and educational purposes. This means we will not be accepting PRs that modify the source in any way.

Gorillas – GW-Basic

A little historical context

The GW-BASIC source code being published is dated Feb 10th 1983. That was quite a while ago, so just to set a little historical perspective:

The week this source was created Men At Work topped the US and UK singles charts with “Down Under”, Dustin Hoffman starred in the #1 US box-office movie, “Tootsie”.

In 1983, “Star Wars Episode VI – Return of the Jedi” was released, as was “War Games”! And, Emily Blunt, Kate Mara, Jonah Hill, Chris Hemsworth, and Henry Cavill, were born! Ronald Reagan was President of the USA, and Margaret Thatcher was the UK’s Prime Minister.

That same year, Bjarne Stroustrup was in the middle of developing the first version of the C++ programming language, ARPANET standardized TCP/IP. Borland announced Turbo Pascal, created by Anders Hejlsberg (who went on to join Microsoft, and create J++, C# and TypeScript).

1983 was also the year AT&T released UNIX System V R1, and BSD 4.2 was released, introducing the pseudoterminal for the first time (the progenitor to Windows’ ConPTY we introduced to Windows in 2018

)

I was 13, and spent every spare second that I wasn’t finishing my homework or doing my chores, writing BASIC and assembly code on one of the hottest home computers of the time – the BBC Micro sporting 32KB RAM (yes, 32,768 bytes, total!), powered by a MOS Technology 6502 processor running at a BLAZING 2MHz.

When not coding, I was usually playing one of the most groundbreaking games of all time: “Elite” by David Braben & Ian Bell.

In 1983, Apple launched the 1MHz 6502-powered Apple IIe for US$1,395 (> $3,500 in 2020). Apple also launched the first commercially available computer with a GUI – the Apple Lisa.

The Lisa contained a staggering 1MB RAM, and ran the awesome Motorola 68000 processor at an astounding 5MHz, but it cost $9,995 (> $25,000 in 2020 dollars), so all I could do was peer at it through the window of the one computer store in our town authorized to sell Apple’s products … and dream.

And, in 1983 Microsoft released MS-DOS 2.0 (source here), and GW-BASIC for the IBM PC XT and compatibles.

What IS GW-BASIC?

GW-BASIC was a BASIC interpreter derived from IBM’s Advanced BASIC/BASICA, which itself was a port of Microsoft BASIC.

Microsoft’s various BASIC implementations can trace their origins all the way back to Bill Gates & Paul Allen’s implementation of Microsoft’s first product – a BASIC interpreter for the Altair 8800.

During the late ’70s and 80s, Microsoft’s BASIC was ported to many OEM’s specific platform and hardware needs, and for several processors popular at that time, including the 8088, 6502, 6809, Z80, and others.

FAQ

Wait – where’s the C source code?

There is no C source code!

Like much software from the 70s and 80s, and just like the source for MS-DOS, the source code of GW-BASIC is 100% assembly language.
