Scott Baker's Comprehensive Content on Magnetic Bubble Memory Technology

In the 1970s, a groundbreaking nonvolatile memory technology named Magnetic Bubble Memory made its debut. However, as we delve into the world of technology, it's clear that this memory has been outperformed in every dimension – durability, reliability, price, density, and performance.

Scott, a tech enthusiast, has taken an interest in this obsolete technology and shares his findings in a blog post. He discusses the Intel 7110 Bubble Memory, also known as "Intel Magnetics" and "Memtech", and other related systems such as the HP 98259 bubble memory boards, the Memtech bubble memory cassette system, the Allen Bradley 8000MBC bubble memory cassette, and Heathkit H8 bubble memory boards.

Scott's article also sheds light on various multibus boards, which can integrate multiple memories, and multimodules, which can plug into multibus boards. He even shares photos of clone multimodules and boards he made himself.

One unique feature of Magnetic Bubble Memory is the defect map, printed on the package and stored within the bubble memory itself. This map helps in avoiding defective storage areas. Interestingly, engineering samples of the Intel 7110 Bubble Memory have the defect map set to "FF", but its meaning remains unclear – whether it signifies defective or not defective storage areas.

For any given application, there is a better alternative technology than Magnetic Bubble Memory. Nevertheless, for those who enjoy delving into the intricacies of old tech, Magnetic Bubble Memory can be an exciting option to explore.

In addition to his exploration of Magnetic Bubble Memory, Scott also mentions the existence of Scott's Basic Bubble Computer. This computer, built around the Magnetic Bubble Memory technology, adds another layer of intrigue to the story of this once-promising memory technology.

As we continue to advance in technology, it's fascinating to take a step back and appreciate the history and evolution of the technologies that came before us. Magnetic Bubble Memory, though outperformed, remains a significant part of that history.
