The Xerox Alto, Smalltalk,
and rewriting a running GUI

We succeeded in running the Smalltalk-76 language on our vintage Xerox Alto; this blog post gives a quick overview of the Smalltalk environment. One unusual feature of Smalltalk is you can view and modify the system's code while the system is running. I demonstrate this by modifying the scrollbar code on a running system.

If you ever connected to the Internet before the 2000s, you probably remember that it made a peculiar sound. But despite becoming so familiar, it remained a mystery for most of us. What do these sounds mean?

Why I Ripped The Same CD 300 Times

I collect music by buying physical CDs, digitizing them with Exact Audio Copy, and scanning the artwork. This is sometimes challenging if the CD was self-published in a limited run in a foreign country ten years ago. It is very challenging if the CDs have a manufacturing defect that renders some tracks unreadable.

Dawn of the Microcomputer:
The Altair 8800

Subscribers to Popular Electronics were a sophisticated group. The magazine’s editor, Arthur Salsberg, felt compelled to point out as much in the editorial section of the December 1974 issue. The magazine had received letters complaining that a recent article, titled “How to Set Up a Home TV Service Shop,” would inspire a horde of amateur TV technicians to go out and undercut professional repairmen, doing great damage to everyone’s TVs in the process. Salsberg thought this concern was based on a misunderstanding about who read Popular Electronics. He explained that, according to the magazine’s own surveys, 52% of Popular Electronics subscribers were electronics professionals of some kind and 150,000 of them had repaired a TV in the last 60 days. Moreover, the average Popular Electronics subscriber had spent $470 on electronics equipment ($3578 in 2018) and possessed such necessities as VOMs, VTVMs, tube testers, transistor testers, r-f signal generators, and scopes. “Popular Electronics readers are not largely neophytes,” Salsberg concluded.

Intel x86 documentation has more
pages than the 6502 has transistors

Microprocessors have become immensely more complex thanks to Moore's Law, but one thing that has been lost is the ability to fully understand them. The 6502 microprocessor was simple enough that its instruction set could almost be memorized. But now processors are so complex that understanding their architecture and instruction set even at a superficial level is a huge task. I've been reverse-engineering parts of the 6502, and with some work you can understand the role of each transistor in the 6502. After studying the x86 instruction set, I started wondering which was bigger: the number of transistors in the 6502 or the number of pages of documentation for the x86.

The 640K memory limit of MS-DOS

The Legend teaches us that Bill Gates once declared that “640 KB ought to be enough for anybody“, then designed MS-DOS to enforce this limitation. The truth is of course a little more complicated than that.
