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.

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.

Commodore 64 vs VIC-20

How do you compare the Commodore 64 vs VIC-20?

The Commodore 64 and its predecessor, the VIC-20, look a lot alike, and the VIC-20’s design certainly influenced the 64. The 64 is the best selling computer model of all time, and I argue the VIC-20 was the first really successful home computer. The success of the two machines allowed Commodore to surpass Radio Shack as the sales leader in the computer industry. Yes, both Commodore and Radio Shack outsold Apple.

But even though the two machines are closely related, there are significant differences between them. It’s important to remember that in the 1980s, two years was a comparatively long time because the market was moving so fast. Plus, the VIC-20 was always supposed to be an entry-level machine. In 1982, the 64 was supposed to be fairly high-end. Let’s compare and contrast the two venerable machines.

CD won’t rip? Try a different drive.

A few weeks ago I uncovered a stash of CDs from my college and early bachelor days that, for one reason or another, I’d never ripped to MP3 format.

When I started ripping the discs, I got one clue as to why I never ripped some of them: Some of them made the DVD drive in my Dell laptop sound like a Commodore 1541. If you ever owned a Commodore, you know exactly what I’m talking about. If you haven’t ever owned a Commodore, let’s just say my drive groaned in protest very loudly, and in exchange for putting up with the noise and insanely long rip times, I received a bunch of errors and a few MP3s that played really poorly.

Commodore hardware viruses–yes, they were possible

Dave Farquhar Retro Computing February 13, 2015June 3, 20241541, 1980s, 6502, commodore, commodore 64

The conventional wisdom is that computer viruses can wipe out your data, but they can’t do physical damage. The exception to that rule was, of course, Commodore, the king of cheap 1980s computers. Commodore’s earliest computer, the PET, had an infamous “poke of death” (POKE 59458,62) that could damage its video display, but the Commodore 64’s sidekick, the 1541 disk drive, had a couple of little-known vulnerabilities as well.

What it was like owning a Commodore in the 1980s

Since questions occasionally come up, and I remember well what it was like owning a Commodore in the 1980s in the United States, I’ll share my recollections of it.

It was very different from computing today. It was still interesting, but it was different. Technology moved fast in the 1980s, so if you blinked, you missed stuff.

The Post-Dispatch may be giving the wrong idea about the dollar value of vintage computers

Disclaimer: I wrote this article back in 2014. I leave it here as a snapshot of the state of how things were in 2014. The situation at the time you are reading this is likely different.

Articles like Top 10 collectibles for value, from the Post-Dispatch this week, frequently make me nervous, mostly because of statements like this one:

[D]id you know that computer parts can bring home cash, too?

Statements like that tend to get people’s hopes up way too high. I find the timing interesting though, seeing as a TRS-80 Model 1 sold at a St. Louis estate sale this past weekend. The estate seller’s reaction? “Normally you can’t give that stuff away.”

LOAD “*”,8,1 – what it means

Dave Farquhar Retro Computing August 28, 2013September 27, 20181541, 1571, commodore, commodore 64, IEEE, nintendo, tape drive

The smartest guy in the room cited the Commodore command LOAD “*”,8,1 as something he used for years but never understood why it worked except it was the command he used to load games on his Commodore 64.

So I explained it. Now I can explain it to you too. Read more

Dredging up some old Commodore trivia

Dave Farquhar Retro Computing May 6, 2012June 17, 20241541, 1571, 1980s, amiga, commodore

I’ve seen a couple of Commodore-related search queries hit lately, so I’m going to take a stroll down memory lane with two questions:

Can you connect two computers to one single 1541 or 1571 disk drive?

And what was the fastest Commodore modem? Read more

Floppy disks for Commodore and other vintage computers

Dave Farquhar Retro Computing June 12, 2011September 9, 20181541, 1571, 1980s, apple, atari, commodore, IBM, vintage computer

It’s been many years since 5.25-inch floppy disks suitable for Commodore, Apple, Atari, and other vintage 8-bit computers (not to mention IBM PCs and PC/XTs) have been something you can buy at the store down the street. I found some 360K DS/DD disks on Amazon, but they aren’t available in huge quantities.
