Microsoft BASIC For 6502 Is Now Open Source

September 4, 2025 by Jenny List 29 Comments

An overriding memory for those who used 8-bit machines back in the day was of using BASIC to program them. Without a disk-based operating system as we would know it today, these systems invariably booted into a BASIC interpreter. In the 1970s the foremost supplier of BASIC interpreters was Microsoft, whose BASIC could be found in Commodore and Apple products among many others. Now we can all legally join in the fun, because the software giant has made version 1.1 of Microsoft BASIC for the 6502 open source under an MIT licence.

This version comes from mid-1978, and supports the Commodore PET as well as the KIM-1 and early Apple models. It won’t be the same as the extended versions found in later home computers such as the Commodore 64, but it still provides plenty of opportunities for retrocomputer enthusiasts to experiment. It’s also not entirely new to the community, because it’s a version that has been doing the rounds unofficially for a long time, but now with any licensing worries cleared up. A neat touch can be found in the GitHub repository, with the dates on the files being 48 years ago.

We look forward to seeing what the community does with this new opportunity, and given that the 50-year-old 6502 is very much still with us we expect some real-hardware projects. Meanwhile this isn’t the first time Microsoft has surprised us with an old product.

Rediscovering Microsoft’s Oddball Music Generator From The 1990s

August 14, 2025 by Lewin Day 8 Comments

There has been a huge proliferation in AI music creation tools of late, and a corresponding uptick in the number of AI artists appearing on streaming services. Well before the modern neural network revolution, though, there was an earlier tool in this same vein. [harke] tells us all about Microsoft Music Producer 1.0, a forgotten relic from the 1990s.

The software wasn’t ever marketed openly. Instead, it was a part of Microsoft Visual InterDev, a web development package from 1997. It allowed the user to select a style, a personality, and a band to play the song, along with details like key, tempo, and the “shape” of the composition. It would then go ahead and algorithmically generate the music using MIDI instruments and in-built synthesized sounds.

As [harke] demonstrates, there are a huge amounts of genres to choose from. Pick one, and you’ll most likely find it sounds nothing like the contemporary genre it’s supposed to be recreating. The more gamey genres, though, like “Adventure” or “Chase” actually sound pretty okay. The moods are hilariously specific, too — you can have a “noble” song, or a “striving” or “serious” one. [harke] also demonstrates building a full song with the “7AM Illusion” preset, exporting the MIDI, and then adding her own instruments and vocals in a DAW to fill it out. The result is what you’d expect from a composition relying on the Microsoft GS Wavetable synth.

Microsoft might not have cornered the generative music market in the 1990s, but generative AI is making huge waves in the industry today.

Hackaday Links: July 27, 2025

July 27, 2025 by Dan Maloney 9 Comments

Sad breaking news late this Sunday afternoon of the passing of nerd icon Tom Lehrer at 97. Coming up through the culture, knowing at least a few of Tom’s ditties, preferably “The Elements” or “Poisoning Pigeons in the Park,” was as essential to proving one’s bona fides as committing most Monty Python bits to memory. Tom had a way with words that belied his background as a mathematician, spicing his sarcastic lyrics with unusual rhymes and topical references that captured the turbulence of the late 50s and early 60s, which is when he wrote most of his well-known stuff. First Ozzy, then Chuck Mangione, now Tom Lehrer — it’s been a rough week for musicians.

Here we go again. It looks like hams have another spectrum grab on their hands, but this time it’s the popular 70-cm band that’s in the crosshairs. Starlink wannabe AST SpaceMobile, which seeks to build a constellation of 248 ridiculously large communication satellites to offer direct-to-device service across the globe, seeks a substantial chunk of the 70-cm band, from 430 to 440 MHz, to control the satellites. This is smack in the middle of the 70-cm amateur radio band allocation here in the US, but covers the entire band for unlucky hams in Europe and the UK. The band is frequently used for repeaters, which newbie hams can easily access using a cheap hand-held radio to start learning the ropes.

Microsoft Looking To Enforce USB-C Features Through WHCP

June 7, 2025 by Maya Posch 36 Comments

As much as people love USB-C, there’s one massive flaw that becomes very obvious the moment you look at the ports on any computer. This being that there’s no (standardized) way to tell what any of those ports do. Some may do display out (Alt-Mode), some may allow for charging, but it remains mostly a matter of praying to the hardware gods. According to a recent blog post, this is where Microsoft will seek to enforce a USB-C feature set on all (mobile) computers compliant with its Windows Hardware Compatibility Program (WHCP).

This also comes after years of the USB Implementers Forum, re-branding the USB specifications, with the most recent iteration thankfully using the bandwidth (in Gbps) as specifier (meaning no ‘USB PlaidSpeed’, sadly). Claiming to follow this end-user friendly spirit, the Microsoft blog post goes on to a minimum set of features that USB-C ports should have, as detailed in the above table.

Most notable is probably that PC charging support is required, as is support for at least one external display. As for the negatives, this seems to only apply to laptops, and no actual charging requirements are set (USB-PD voltages, wattage, etc.), so what the actual impact of this will be remains to be seen.

One thing remains certain, however, and that is that by trying to make USB-C the One True Connector for literally everything, there will always remain cases where end-user expectations remain unfulfilled.

An LLM For The Raspberry Pi

May 10, 2025 by Al Williams 32 Comments

Microsoft’s latest Phi4 LLM has 14 billion parameters that require about 11 GB of storage. Can you run it on a Raspberry Pi? Get serious. However, the Phi4-mini-reasoning model is a cut-down version with “only” 3.8 billion parameters that requires 3.2 GB. That’s more realistic and, in a recent video, [Gary Explains] tells you how to add this LLM to your Raspberry Pi arsenal.

The version [Gary] uses has four-bit quantization and, as you might expect, the performance isn’t going to be stellar. If you are versed in all the LLM lingo, the quantization is the way weights are stored, and, in general, the more parameters a model uses, the more things it can figure out.

Celebrating 30 Years Of Windows 95 At VCF

April 6, 2025 by Adam Fabio 78 Comments

It’s been 30 years since Windows 95 launched. [Ms-Dos5] and [Commodore Z] are celebrating with an epic exhibit at Vintage Computer Festival East 2025. They had no fewer than nine computers — all period-correct machines running versions of Windows 95. The pictures don’t do it justice, so if you are near Wall, NJ, on Sunday, April 5, 2025, definitely go check out this and the rest of the exhibits at VCF.

An exhibit like this isn’t thrown together overnight. [Commodore Z] and [Ms-Dos5] worked for months to assemble the right mix of desktops, laptops, and peripherals to showcase Windows 95. Many of the computers are networked as well – which was no easy task.

One particular Thinkpad 760e required pliers and force to remove a stuck PCMCIA modem card. After a struggle that was ultimately destructive to the card, the pair determined it was stuck due to a sticker that had effectively glued the card into the laptop. As the sticker finally gave up, the card popped itself out of the laptop.

A Very Trippy Look At Microsoft’s Beginnings

April 3, 2025 by Tom Nardi 38 Comments

It’s not often you’ll see us singing the praises of Microsoft on these pages, but credit where credit is due, this first-person account of how the software giant got its foot in the proverbial door by Bill Gates himself is pretty slick.

Now it’s not the story that has us excited, mind you. It’s the website itself. As you scroll down the page, the text and images morph around in a very pleasing and retro-inspired way. Running your cursor over the text makes it flip through random ASCII characters, reminding us a bit of the “decryption” effect from Sneakers. Even the static images have dithering applied to them as if they’re being rendered on some ancient piece of hardware. We don’t know who’s doing Billy’s web design, but we’d love to have them come refresh our Retro Edition.
