Emulate the VIC-20 home computer with Linux

Filed under
Hardware

Emulation is the practice of using a program (called an emulator) on a PC to mimic the behaviour of a home computer or a video game console, in order to play (usually retro) games on a computer.

Home computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single non-technical user.

Back in the 1980s, home computers came to the forefront of teenagers’ minds. Specifically, the Amiga, ZX Spectrum, and Atari ST were extremely popular. They were hugely popular home computers targeted heavily towards games, but they also ran other types of software.

The Commodore VIC-20 is an 8-bit home computer that was released in 1980/1. It featured a MOS Technology 6502 CPU, with 20KB ROM and 5KB RAM although 1.5K of the RAM was used for the video display and aspects of the BASIC and kernal.

It offered limited low-resolution graphics (176 x 184) with storage provided by cassette and floppy disk.

MNT Pocket Reform 7-inch modular mini laptop takes a range of Arm (and FPGA) modules

MNT Pocket Reform is an open-source hardware mini laptop with a 7-inch Full HD display, an ortholinear mechanical keyboard, and trackball, that follows the path of its older and bigger sibling: the MNT Reform 2 laptop initially launched with an NXP i.MX 8M quad-core Arm Cortex-A53 module. The new laptop will not only support a similar “NXP i.MX 8M Plus” module but also a range of other Arm modules namely an NXP Layerscape LS1028A module with up to 16GB RAM, the Raspberry Pi CM4 module via an adapter, Pine64 SOQuartz (RK3566, up to 8GB RAM), as well as based on AMD Xilinx Kintex-7 FPGA for industrial use.

IPFire 2.27 - Core Update 169 is available for testing

The next Core Update - one of the biggest in size we have ever put together - is available for testing. It introduces the support of two-factor authentication (2FA) for OpenVPN clients, updates several core parts of the system, provides mitigations for another two types of CPU side-channel attacks, as well as package updates, bug fixes and other security improvements. For OpenVPN clients, the setup of two-factor authentication based on time-based one-time password (TOTP) is now supported. It can either be enforced on a per-client basis, preserving the flexibility of mixing end-user devices with machine clients, where no manual interaction is feasible during OpenVPN connection establishment.

9 Top Free and Open Source Elixir Web Frameworks

One of the types of software that’s important for a web developer is the web framework. A framework “is a code library that makes a developer’s life easier when building reliable, scalable, and maintainable web applications” by providing reusable code or extensions for common operations. By saving development time, developers can concentrate on application logic rather than mundane elements. A web framework offers the developer a choice about how to solve a specific problem. By using a framework, a developer lets the framework control portions of their application. While it’s perfectly possible to code a web application without using a framework, it’s more practical to use one. Read more
