In my last post , I figured out how to use Apple’s leaked Flasher utility from the 1990s to reflash a ROM SIMM inside of my Performa 630. It’s basically the Mac equivalent of a BIOS update, but only for Apple’s developers. The research involved in that post was quite a journey of reverse engineering from both a…
Last week, US Steel announced it was being acquired by Japanese steel company Nippon Steel.
Roman soldiers weren't paid in salt, and they weren't given "salt money". Dictionaries of the 1700s and early 1800s are to blame for this myth.
A deep dive into the text mode editors we had and how they compare to today's
I think it is healthy to compare historical and modern computing. Let's see how the CPUs contained in recent USB-C wall chargers compare to the power of the Apollo 11 Guidance Computer (AGC). The Apollo 11 spacecraft carried 3 humans to the moon and back in 1969.
BASIC is often dismissed as an inferior language compared to its successors. Common complaints are its use of line numbers, its heavy reliance on GOTO for execution flow, and its lack of a stack for local variables. What many critics overlook is that at the time of its use (during the first wave of home computers)…
An in-depth analysis that explains how this console works internally
One of my most popular posts was also my very first… which has since been lost to the Great Blog Devouring of ’14. So… here’s the post from over ten years ago (has it been that long?!?!?!) about an event from almost twenty years ago. Still stuff I have to remind myself about some days.

Cray 1 Supercomputer Performance Comparisons With Home Computers Phones and Tablets
I’ve been buying a copy of Maximum PC magazine at the airport newsstand on every long-distance trip I’ve taken over the past two decades. I’m primarily a Mac user but Maximum PC, which started life as boot, bought at these … Continue reading →
The second block has more real work going on. If the character stored in the variable _ does not match the first character of the string a , the code recurses in such a way that this same block of code will again be entered. That is, t=-65 forces a return to the if (t < -50) block. The recursion steps through string a…
Everything was fine until BASIC entered the picture. Edsger Dijkstra in a hallucination of 2023’s AI Simplicity is the ultimate sophistication. Leonardo Da Vinci It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: as potential programmers they are mentally…

One of the first questions anyone asks about past societies is, ‘how many people were there?’ It is one of those basic bits of information and generally speaking those of us who teach t…
Blue Scuti made history, breaking NES Tetris in a way that was previously only theoretical. Here is a glimpse into the what, who, and how.
While repairing an eight-inch HP floppy drive, we found that the problem was a broken interface chip. Since the chip was bad, I decapped it ...

It was a happy time for PC users. Microsoft had just delivered Windows 95, an incredibly vast improvement over windows 3.1 and DOS.
In 2001, digital cameras were a rare commodity. They were expensive, bulky and captured images that were inferior to the organic look of…

Part 1 of the story of Motorola's 8-bit microprocessor design
It’s 1995 and I’ve been nearly two years in the professional workspace. OS/2 is the dominant workstation product, Netware servers rule the world, and the year of the Linux desktop is going to happen any moment now. If you weren’t running OS/2, you were probably running Windows 3.1, only very few people were using that…
How a mistake of less than half a millimeter in a single part nearly brought down the world’s largest passenger aircraft.
Why do the 8-bit designs of the 1970s still generate so much interest?
Filipe Cruz (aka psenough) invited me to Inércia 2023, a local Demoscene event organized by the Associação Inércia that took place in the infamous Incrível Almadense. I’ve done my fair share of bouncing ball assembly demos in the 80s and others more recently, but I don’t qualify as a demoscener, not even by the lowest…
A study of associations between stone tool evidence and fossil hominin remains shows that a wide range of species made stone artifacts.
October 1982 TR-03.214 A PERSONAL HISTORY OF APL by Michael S. Montalbano International Business Machines Corporation General Products Division Santa Teresa Laboratory San Jose, California A PERSONAL HISTORY OF APL Introduction I have several reasons for calling this talk a personal history. For one, I want to make it…
Nike computer - Installed in class room, not BC van. From Rolf Goerigk Left rack has the power supplies - outputs about 7 different voltages. Top panel is switches, meters, voltage warning lights.
