Commodore Plus 4 and Commodore 16

Dan Bowman kindly pointed me to former Commodore engineer Bil Herd’s discussion of the ill-fated Commodore TED machines on Hackaday. Here in the States, few remember the TED specifically, but some people may remember that oddball Commodore Plus 4 that closeout companies sold for $79 in 1985 and 1986. The Commodore Plus 4 was one of those TED machines. So was the Commodore 16.

What went wrong with those machines? Commodore miscalculated what the home computer market was doing. The TED was a solution to too many problems, and ended up not solving any of them all that well. Arguably it’s more popular with vintage computer enthusiasts today than it was in the 1980s. Read more

Computers in 1985: It was a very good year

In some ways, 1985 was a really pivotal year for computing. The industry was changing fast, but in 1985, many relics from the past were still present even as we had an eye for the future. Here’s a look back at computers in 1985 and what made that year so interesting.

I think 1985 was interesting in and of itself, but it also made the succeeding years a lot more interesting. A surprising amount of the technology that first appeared in 1985 still has an impact today.

Commodore 64 common questions and answers

Dave Farquhar Retro Computing April 14, 2017August 5, 20171541, 1980s, 1990s, Baby Boomers, commodore, commodore 128, commodore 64, estate sales, garage sales, irving gould, Japan, Korea

I hear a lot of questions about the Commodore 64 over and over again. Many of them don’t warrant a single blog post. So here’s a list of Commodore 64 common questions and their answers.

If you want to know when the Commodore 64 came out, how many Commodore 64s sold, who made the Commodore 64, where the Commodore 64 was made, is the Commodore 64 worth anything, are Commodore 64 games worth anything, or if you can still buy a Commodore 64, read on.

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?

Commodore 64 vs 128

Dave Farquhar Retro Computing May 19, 2016October 26, 20221541, 1571, 1980s, 6502, amiga, apple, apple ii, c64, commodore, commodore 128, commodore 64, tape drive

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.

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.”

How the Amiga could have lived to age 30 and beyond

It was 30 years ago this week that Commodore released its landmark, long-time-coming Amiga 1000 computer–the first 1990s computer in a field full of 1970s retreads.

Yes, it was a 1990s computer in 1985. It had color and sound built in, not as expensive, clunky, hard-to-configure add-ons. It could address up to 8 megabytes of memory, though it ran admirably on a mere 512 kilobytes. Most importantly, it had fully pre-emptive multitasking, something that previously only existed in commercial workstations that cost five figures.

It was so revolutionary that even NBC is acknowledging the anniversary.

Being a decade or so ahead of its time was only the beginning of its problems, unfortunately.

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 forgotten computer that changed the world

Dave Farquhar Retro Computing July 22, 2014December 6, 2020amiga, apple, apple ii, commodore, commodore 128, IBM, macintosh

A rather hastily written and sloppily edited piece showed up on Slashdot yesterday morning that caught my attention, because it was about the Amiga 2000. The Amiga 2000 is a dear machine to me; in 1991, our family upgraded to one from a Commodore 128. I still have both machines, and there isn’t much that I know today that I didn’t first experience on one of those two machines.

This is an Amiga 2000 that looks fairly pristine. Inside there was lots of room for hard drives, memory, CPU upgrades, and video devices.

Although I think the piece was little more than a used computer store’s effort to unload some hard-to-move inventory, I do agree with the premise. For a machine that had a tremendous impact on the world as we know it today, the A2000 is criminally unknown. Read more
