Let's look at this little gizmo Sony produced in the early 1990s.
In 2004 I built the first AppleCrate , an 8-board system, as an inexpensive, easy to program vehicle for experiments in parallel programming�a kind of "blade server" for the Apple II, if you will! AppleCrate I (at the time I didn't realize that it was number "I" ;-) was great fun, and it enabled some very interesting…

An in-depth analysis that explains how this console works internally
From OP 2230, "Workmanship and Design Practices for Electronic Equipment" , published by the direction of the chief of the Bureau of Naval Weapons , 1 December, 1962. pp. 7-9 --- 7-14.
EDIT - the original article has an image of the PCB with the floppy power connector mounted the WRONG WAY. This is the INCORRECT WAY. Do NO...
The memory management in DOS is simple, but that simplicity may be deceptive. There are several rather interesting pitfalls that programming documentation often does not mention.
To kick off MARCHintosh, I built this tiny pint-sized Macintosh with a Raspberry Pi Pico: This is not my own doing—I just assembled the parts to run Matt Evans' Pico Micro Mac firmware on a Raspberry Pi Pico (with an RP2040). The version I built outputs to a 640x480 VGA display at 60 Hz, and allows you to plug in a…

In 1994, a teenager wanted to be noticed in the ANSI art scene. So he created "Inspector Dangerfuck": a profane, stoned, gray-skinned cartoon detective.
This week, we got the emulation of MS-DOS programs (mostly) working on the Internet Archive. Up to now, every single emulated system has been via the JSMESS project, which supports well over 600 sy…
Editor’s Note: This article ends on a cliffhanger. The next part goes out in a week. I will start with an honest admission. I didn’t set out to write about the world’s first app store. I set out to write about Brother printers. But doing my research,
Some final thoughts on this epic expedition.
While there may be some situations in which DOS has a better command, Unix works better overall.
It was a happy time for PC users. Microsoft had just delivered Windows 95, an incredibly vast improvement over windows 3.1 and DOS.
"Why do you jackasses use these inferior linguistic vehicles when we have something here that’s so precious, so elegant, which gives me so ...
{This material originally appeared in the March, 1991 International Edition of Byte magazine, a McGraw-Hill publication} To describe TAOS (pronounced 'dowse' as in the oriental religion Daoism) as an innovatory operating system would be a profound understatement. It has so few points of
This blog has previously examined a very very strange code fragment in the BIOS module of DOS. To recap, when deciding whether a boot sector might have a valid BPB, DOS checks whether the first byte is a relative jump (opcode E9h) or a short jump (opcode EBh), both used by different DOS versions. But it also checks…
There is a story repeated so often that it has become a truth -- that medieval folk drank weak beer to avoid the perils of drinking water -- but it's a myth.
A while ago I decided to pick up some 35mm cinema film to help me experiment with projection optics.
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
This led to some general discussion that this particular device really is in a class of devices, now called the "killers", which need to be made.
I found an old pad of graph paper in my father's desk and was reminded of the days of plotting by hand.
For those of us around Apple for the launch of the 1984 Mac, things are awfully familiar.
Last January the Steve Jobs movie came to town and called me up. I was leaving work one day when I got a phone call from a guy named Todd ...
