The silver label Commodore 64

The silver label Commodore 64

The most valuable examples of the Commodore 64, generally speaking, are the early variants that have silver labels across the top. The silver label Commodore 64 is the earliest, most expensive example of the venerable machine.

In all, Commodore produced about 80,000 of these machines. That compares to several million of the most common variants. That alone makes early models relatively rare. When you do find one, there’s a fairly good chance it’s not 100% original. The silver label Commodore 64 is the equivalent of the Atari 2600 heavy sixer, but more rare.

Origin of CP/M’s PIP command

Origin of CP/M’s PIP command

CP/M was, as you probably know, the first popular microcomputer operating system. It was good but imperfect, and its cryptic command for copying files, PIP, is often cited as an example. Copy makes sense. Even the Unix equivalent, cp, makes sense–it’s copy without the vowels. But what does PIP mean? What’s the origin of CP/M’s PIP command?

Gary Kildall’s death investigation

Gary Kildall’s death investigation

Gary Kildall’s death investigation, or the seeming lack thereof, has taken on mythical proportions. Gary Kildall’s story seems to have that effect on people.

While Gary Kildall died under unclear circumstances, his death was less unusual than early accounts made it seem. That’s why the investigation seemed to fizzle out with less fanfare than it deserved.

Commodore 64 vs 128

Commodore 64 vs 128

Commodore introduced the Commodore 128 in 1985 as an upgrade path from the Commodore 64, the most popular model of computer of all time. The 128 addressed the 64’s biggest shortcomings while remaining mostly compatible with its hardware and software. That makes the Commodore 64 vs 128 a natural comparison, even more natural than comparing the 64 with the VIC-20.

The Commodore 128 was an extension of the Commodore 64, with more memory, a faster disk drive, a faster CPU, and 80-column video. It also featured a very high degree of compatibility, which helped both machines sell better.

Commodore 64 vs 64c

Commodore 64 vs 64c

The Commodore 64 went through a number of revisions throughout its long life. The most outwardly visible of those revisions was the transition from the tan, boxy C-64 to the thinner, lighter-colored 64c. If you’e wondering about the Commodore 64 vs 64c, here’s what you need to know.

C64 vs Apple II

C64 vs Apple II

The C64 vs Apple II was perhaps the most epic battle of the 8-bit era. Both companies sold millions of machines, yet both nearly went out of business in the process.

Comparing the two machines with the largest software libraries of the 8-bit era is a bit difficult, but that’s what makes it fun. The two machines are similar enough that some people ask if the Commodore 64 was an Apple product. The answer is no.

As a weird aside, it was possible, with a Mimic Systems Spartan, to turn a C-64 into an Apple II. Not many did, but the reason why is another story.

Cleaning electrical contacts with Everclear

Cleaning electrical contacts with Everclear

When I was 19 or 20, I paid a visit to my old grade school to do some computer repair. My fifth-grade teacher dropped in, saw me cleaning up the contacts on a circuit board, and asked why I wasn’t using Everclear. Cleaning electrical contacts with Everclear is, at least, a practice people talk about a lot.

Well, I couldn’t legally buy Everclear yet, for one thing. But let’s talk about why Everclear is good for cleaning electrical contacts but there are other things that can be better.

Advantages and disadvantages of Windows 3.0

Advantages and disadvantages of Windows 3.0

I hear the question from time to time what the advantages and disadvantages of Windows 3.0 were. Windows 3.0, released in May 1990, is generally considered the first usable version of Microsoft Windows. The oft-repeated advice to always wait for Microsoft’s version 3 is a direct reference to Windows 3.0 that still gets repeated today, frequently.

Although Windows 3.0 is clumsy by today’s standards, in 1990 it had the right combination of everything to take the world by storm.

Who bought Commodore

Commodore International went out of business in 1994, after nearly a decade of declining revenue. But the company left a significant legacy, which leads to some logical questions. What became of Commodore? Who bought Commodore?

Mehdi Ali: Commodore spinmeister

Mehdi Ali: Commodore spinmeister

I found the thumbnail biography of one Mehdi Ali recently. It reads, in part:

“His prior experience includes serving as the President of Commodore International, where he accomplished a major operational turnaround.”

I don’t think he and I share the same definition of “major operational turnaround.”
