Epyx Fast Load cartridge

Dave Farquhar Retro Computing May 12, 2017September 15, 20221541, commodore, commodore 64, tape drive

The Epyx Fast Load cartridge, released in 1984, was the first commercially successful Commodore 64 fast load product. Commodore’s 1541 disk drive was much slower than competing disk drives, so fast load cartridges became popular. While the Epyx product was first, and sold very well, it didn’t have the market to itself for long. Its developer, Scott Nelson, went on to produce other fast loader products as well.

Epyx Fast Load was a plug-in cartridge that replaced the Commodore 64’s stock ROM disk loading routine with a more efficient routine that was about five times as fast. The result was that software that normally took three minutes to load often took closer to 30 seconds with the cartridge.

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.

1541 vs 1541C

The dark beige/tan Commodore 1541 disk drive is rather well known. The lighter beige, almost white 1541c is more of a curiosity. The drives are closely related, but the difference is more than just the color. Let’s take a look at the 1541 vs 1541c.

Commodore 64 vs Amiga

Looking at the Commodore 64 vs Amiga seems a little odd, at least to me. After all, the machines were never intended to be rivals. The Amiga was supposed to succeed the 64. Commodore bought Amiga because they couldn’t make a 64 successor on their own, so they intended for the Amiga to replace it. It didn’t fully succeed, and maybe that’s why the comparison is still interesting.

Looking back, the machines may seem similar today. But in 1985 they sure didn’t.

Commodore 1541 vs clones

The battle of the Commodore 1541 vs clones existed because Commodore’s early track record was rather imperfect.

Commodore’s 1541 floppy disk drive was the first consumer disk drive that cost less than $300, so it has an important place in computing history.

What some people forget is that while it broke new ground, its early owners loved to hate it. It was slow, it was loud, and ran hot. Early units were unreliable too. And to add insult to injury, in 1982 and 1983, Commodore couldn’t build them fast enough to keep up with demand. Even though it had problems, people were eager to buy it. (Disk drives for other computers tended to be problematic too, in this young industry.)

The 1541’s problems led to a number of clones that tried to be a little bit better.

Meaning of the word commodore

Dave Farquhar Retro Computing January 24, 2017April 9, 20171980s, 1990s, commodore, jack tramiel

Commodore was a high-flying 1980s computer company that imploded in the early 1990s. But the name is a bit curious. What is the meaning of the word commodore?

An LCD monitor for retro computing

Purists prefer CRT monitors for a more authentic experience, but if you don’t mind an LCD, here’s a good LCD monitor for retro computing. Look for a Dell 2001fp manufactured in June 2005 or before. For bonus points, try to find one with a soundbar.

Commodore 64 commands

Dave Farquhar Retro Computing October 4, 2016July 11, 2018cmd, commodore, commodore 64, unix

People frequently ask me for a list of common or useful Commodore 64 commands, including disk drive commands. Since the C-64’s built in operating system is more of a combination command line/Basic interpreter, it takes some getting used to if you didn’t grow up with it.

These commands assume a stock, unmodified C-64, freshly powered on. Many fast-load cartridges, ROM replacements, or so-called DOS wedge programs include shortcuts for these commands. But these commands work on any C-64 with a disk drive, modified or stock.

Commodore 1541-II DIP switches

Dave Farquhar Retro Computing September 21, 2016June 20, 20211541, commodore

Commodore’s 1541-II disk drive has a pair of DIP switches on the back to let you change its device number. DOS and Windows computers use drive letters to address its disk drives (usually A: and B:). Commodore used the numbers 8-11 to address them. Here’s how to set the 1541-II DIP switches so you can run more than one drive.

Commodore 1540 vs 1541 disk drive

Dave Farquhar Retro Computing August 25, 2016October 11, 20251541, commodore, FCC

The dark tan 1541 is the most common C-64 peripheral in existence. Its counterpart for the VIC-20, which looks exactly like it at first glance, is pretty rare. The 1540 vs 1541 is a fairly common topic among Commodore enthusiasts.
