Hello! It has been a little while, but #nakeddiefriday is back in town.
Today's exhibit is an old PIC1650A. Yes, one of *the* PIC series of microcontrollers. Note it was designed by General Instrument in 1980. It was fabbed in a single metal layer, metal-gate NMOS process. The image is about 4.3x3.8 mm.
No full-res link as SP is still borked.

AI can explain disassembly, but security still depends on good design.
🔐 Episode 519: Password Is All Zeros
In this episode, Elecia and Chris joined by Mark O. and James Rowley to explore:
- The fascinating world of safecracking
- How the lock industry often operates in isolation from broader security practices
- The ethics of doing a bad job when building systems meant to protect lives and property

This tutorial will discuss hacking double variables.
«Ma che cosa è cambiato da allora?»
«Perché nessuno realizza più progetti così fighi?»
... ci siamo chiesti, io e questo mio amico...

Beh...
Sicuramente è cambiata l'industria: ora si spinge - molto di più - sui #FreeToPlay con le #MicroTransazioni.
Perché qualcuno dovrebbe investire il proprio tempo per fare #ReverseEngineering di qualcosa che è già gratuito, per definizione?
Eppure - già all'epoca - alcuni di questi titoli erano già free-to-play: vedi, ad esempio, #Metin2.
Quindi? 🤔

He picked up a Motorola 68000 based machine at a local swap meet. A few boards, a backplane, and a power supply. The only information provided is the machines original purpose: gas station pump control.</p>
<p>The computer in question is an embedded system. It uses a VME backplane, and all the cards are of the 3u variaety. The 68k and associated support chips are on one card. Memory is on another. A third card contains four serial ports. The software lives across three different EPROM chips. Time for a bit of reverse engineering!</p>
<p><span id="more-914854"></span></p>
<p>[Dave] quickly dumped the ROMs and looked for strings. Since the 68k is a big endian machine, some byte swapping was required to get things human readable. Once byte swapped, huge tables of human readable strings revealed themselves, including an OS version. The computer runs <a href="https://en.wikipedia.org/wiki/PSOS_(real-time_operating_system)" target="_blank">pSOS</a>, an older 68k based real time operating system – exactly what one would expect a machine from the 80’s to run.</p>

I have this amazing weird little camera with a built in projector. A Nikon coolpix S1000pj from 2009. It's perfect for partypics and fits about 80 photos on a 256 MB SD-Card but there is one thing that would make it even cooler - if it could just project any image on the card! But it doesn't. Even editing a jpg from the card with the metadata staying intact gets rejected. There has to be a way to make that work but it's outside of my skills... Maybe someone here has any ideas or has even figured that out? A little script to make images compatible would be a dream!
