    RaspArch for Raspberry Pi 5

    RaspArch for Raspberry Pi 5

    RaspArch :: Run Arch Linux on your Raspberry Pi 5

    ABOUT RaspArch is a “ready-to-go” ARM (aarch64) system. It can only run on a Raspberry Pi 5 computer. Build 260111 runs only on a Rpi5. INSTALLATION Use Rufus or Etcher in Windows. MORE about RaspArch When you have installed RaspArch to your Micro SD Card you can use the system like any other Arch Linux (aarch64) system. I.e. install new programs etc. Arch motto is KISS ("Keep It Simple Stupid"). WHO SHOULD RUN Arch Linux/RaspArch? My answer: The system fits the “advanced” Linux user/enthusiast, who would be willing to run an occasional command from time to time. UNIQUE There is no other (good) Arch Linux System for Raspberry Pi 5. Not for downloading anyway. PERFORMANCE Everything works! The System is responsive and quite fast, especially when logged in as the normal user archpi. Desktop Environment: LXQt 2.3. KERNEL In Build 260111: 6.18.4-1-rpi-16k

    ttf-gdos

    TTF-GDOS is an Atari GDOS replacement that uses true type fonts

    TTF-GDOS is a GDOS replacement that uses true type fonts as well as gem fonts. It is small, fast & efficient and can easily be used without a hard drive. It also incorporates features roughly equivalent to font-GDOS: - a caching system so you can use more fonts for a given amount of memory, - built in bezier functions This release includes ttf2gem, a utility program that creates accurate gem fonts from a true type font (new for 2.3) Using true type fonts gives you 3 big benefits: - you can choose from a vast range of true type fonts - true type fonts are scalable so you can have almost any size font you want - true type fonts need much less disk storage than typical gem printer fonts, so even on a low spec machine you can use lots of fonts. Gem fonts and true type fonts complement each other perfectly - gem fonts are small and fast, while true type fonts are device and resolution independent so are scalable to any point size at any resolution.
