This post has a little bit of everything. Hardware diagnostics, some suspiciously similar datasheets from two separate Taiwan chip manufacturers, and firmware reverse engineering. Read on if that sounds like fun!| Downtown Doug Brown
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 software and hardware perspective. I had to disassemble the code to figure out which computers were compatible and what the software was expecting to find. I also had to create a ...| Downtown Doug Brown
