Manufacturing is hard. The thickness of my supplier’s clear acrylic material has magically increased 15%, meaning that the latest batch of Floppy Emu acrylic cases are impossible to assemble. The buttons and light pipes don’t fit in the cut-outs made…
Watch this video on YouTube After a long hiatus, there’s new progress for the Plus Too FPGA-based Macintosh replica. Till Harbaum has ported my original, unfinished design to the MiST board, and has begun making fixes and improvements. The video…
Make a Windows program by stuffing bytes into a buffer and writing it to disk: no compiler, no assembler, no linker, no nothing! It was the obvious conclusion of my recent efforts to gain more control over what goes into…
Who says assembly language programming is dead? Keeping with my recent theme of peering inside Windows executable files, I decided to bypass C++ completely and try writing a Windows program entirely in assembly language. I was happy to discover that…
Did you know that a C program’s main() function is not the first code to be run? Depending on the program and the compiler, there are all kinds of interesting and complex functions that get run before main(), automatically inserted…
Did you ever wonder what’s used to stuff the sausage of a Windows executable file? In yesterday’s post I examined a simple text-only C program, and discovered that 18 lines of C code created a 6144 byte executable program. Using…
Want to know more about how assembly code works, and how Windows executable programs are put together? I thought it would be fun to write a “hello world” program in C, and then examine it with some common reversing tools,…
A 14-year-old Texas high school student has been arrested, suspended, and threatened with expulsion for bringing a hand-made digital clock to school, after officials and police believed he’d tried to make a bomb. This kid loves robotics, makes his own…
How would you use modern RAM and interface logic to replace 8 MB of vintage SRAM? A cheap and simple solution would make a big difference for many retrocomputing and hobby electronics projects. This question arose from a discussion at…
