Epyx Fast Load cartridge

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.

Taming Windows 95/98/98SE/ME Out of Memory Errors

Dave Farquhar Retro Computing, Windows April 6, 2017September 10, 2023disk cache, optimizing windows, win9x, windows 2000, windows 7, windows 9x

The symptom: If you install more than 512 MB of RAM in a system running Windows 9x (that’s any version of Windows 95, 98, 98SE, or ME), you get weird out of memory errors. Here’s how to get around those memory limitations to make Windows 95 and Windows 98 work with 2 GB of RAM.

The culprit is a bug in Windows 9x’s disk cache. The solution is to limit the cache to use 512MB of memory, or less, which is a good thing to do anyway.

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.

Advantages and disadvantages of Lotus 1-2-3

Lotus 1-2-3 was the killer app that made the IBM PC the standard for computers. It wasn’t the first spreadsheet, but it ran on a computer that could easily address more than 64K of memory, it was fast, and relatively bug free. So it was super successful. Today we know it as the thing people used before Excel. So what were the advantages and disadvantages of Lotus 1-2-3?

Why Jack Tramiel left Commodore

Retro computing fans, especially Commodore and Atari enthusiasts, all know the story. Jack Tramiel left Commodore, the company he founded, in early 1984 at the height of its success. Then, within a few months, he gained control of Commodore rival Atari.

But why?

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

Dave Farquhar Retro Computing February 3, 2017May 8, 20241541, capacitors, commodore, MOS, power brick

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?

Whatever happened to Dr. Thomas Pabst?

Dave Farquhar Retro Computing January 16, 2017March 27, 2023

In 1996, Dr. Thomas Pabst, a German MD then living in England, created a web page where he talked about motherboards, video cards, and a then little-known phenomenon called overclocking. Dubbed Tom’s Hardware Guide, Dr. Pabst’s hobby site spawned a long list of imitators, creating a new industry: PC hardware enthusiast sites.

In 2006 he sold the site and walked away.
