A USB floppy drive for retro computing

A USB floppy drive for retro computing

One of the reasons people keep a bridge PC around is the difficulty of writing 720k double density floppies with a modern USB floppy drive. In this blog post, I’ll share the secret of the MPF82E, a USB floppy drive that can write double density 720K disks, making it ideal for retro computing.

Chips and Technologies Super 386: A forbidden CPU

Chips and Technologies Super 386: A forbidden CPU

UMC wasn’t the only company with a forbidden CPU in the 90s. Fellow chip set maker Chips and Technologies took a somewhat similar approach late in the previous generation, with an independently created clean room implementation of the 386. This short-lived CPU may be the rarest 386.

Commodore 2031 disk drive: Last of its kind

Commodore 2031 disk drive: Last of its kind

Later revisions of the Commodore 2031 look just like the 1541. But was this drive just the IEEE version of the 1541? And what about this drive almost made the 1541 not happen at all? In this blog post, we will dig into the last 170k IEEE drive Commodore made for the PET series, from 1981 to 1983.

CMD FD-2000 and 4000: High density and beyond for the C-64

CMD FD-2000 and 4000: High density and beyond for the C-64

In 1992, the Commodore 64 was fading. You may be surprised to hear it was still the number three gaming computer in terms of market share in the United States, but its growth years were in the distant past. That year, a new third party disk drive appeared or the C-64. Sometimes when you do something for the last time, you don’t realize it will be the last. In this case, I think everyone knew these drives were the end of the line. But what a finale they were.

Franklin Computer: Rise and fall and reinvention

Franklin Computer: Rise and fall and reinvention

In 1981, a Philadelphia-area company called Franklin Computer had a good idea that didn’t work out so well for them. They decided to clone Apple computers. They ended up on the wrong end of a landmark lawsuit and yet they succeeded at reinventing themselves. In this blog post, I will go through the rise and fall and rebirth of Franklin Computer Corporation.

Commodore 1670 modem 1200

It was 1985. Just 3 years before, Commodore had made telecommunications affordable, releasing the first modem on the market that retailed for $100. They weren’t just making it possible to live in the future, they were making it affordable. But the industry was passing them by. Commodore needed to catch up, and the 1670 modem 1200 was what they came up with.

UMC Green CPU: The forbidden 486

UMC Green CPU: The forbidden 486

Clock for clock, the best 486 was a CPU you might not have been able to buy and may very well have never heard of. Aside from Intel, AMD, and Cyrix, there was a fourth 486 family that didn’t get very far due to legal issues: the UMC Green 486 CPU. In this blog post, we will cover what made this 486 so special and what made this forbidden 486 illegal.

Maverick: Final-generation C-64 copier

When I wrote my blog post about Fast Hack’em, a fair number of C-64 fans said they preferred Maverick. I seem to recall a lot of those kinds of conversations in the ’80s as well.

Why SID chips go bad sitting on a shelf

Why SID chips go bad sitting on a shelf

The distinctive thing about the Commodore 64 was its custom chips. And while the VIC-II chip provided competitive graphics, the 64’s secret weapon was the sound interface device, also known as the SID. The Mastermind behind the SID was a young chip designer named Robert Yannes, who went on to found the synthesizer company Ensoniq. But the chips frequently fail today and the problem is getting worse. Here’s why 6581 SID chips can go bad just sitting on a shelf.
