The MMI 5300 was a memory chip from the early 1970s, storing 1024 bits in tiny fuses.1 Unlike regular RAM chips, this was a PROM (Programmable Read-Only Memory); you programmed it once by blowing fuses and then it held that data permanently.

If you’re looking to get a better handle on how to read schematics, this helpful guide will give you a head start. Every new electrical circuit board design starts as an idea. That idea is then defined, with words and diagrams, in a specification.

Have you ever needed a clock speed that wasn’t easy to generate? What if you wanted to build and run your own PLL? Within an FPGA?? As an example, many of my favorite FPGA boards have 100MHz clocks coming into them.

Our ECE 5760 Final Project uses the Terasic DE1-SoC’s Cyclone V FPGA and Cortex-A9 cores to fully simulate a Xilinx XC6200 FPGA. We test the functionity of the hardware-simulated FPGA and experiment on its ability to discern between input frequences using a genetic algorithm.

Never use a lousy schematic editor again! SKiDL is a simple module that lets you describe electronic circuits using Python. The resulting Python program outputs a netlist that a PCB layout tool uses to create a finished circuit board.

We will admit it: mostly when we see a homebrew CPU design on an FPGA, it is a simple design that wouldn’t raise any eyebrows in the 1970s or 1980s. Not so with [Henry Wong’s] design, though. His x86-like design does superscalar out-of-order execution, just like big commercial modern CPUs.

Making a copy of a purchased game used to be as simple as copying a disk. As the game industry grew, so did fear of revenue loss which drove investment in countermeasures.

While it might not be quite as revered as its predecessor, the Game Boy Advance is arguably the peak of “classic” handheld gaming, before things got all 3D and dual screen on us.

Many old Commodore 64/1541 disks have read errors, but this doesn’t mean the data isn’t recoverable – with the right nibtools settings and some cleaning. The ZoomFloppy adapter is the de-facto standard for connecting Commodore disk drives to modern computers, using a USB connection.
