Matrix Inspired NABU Digi Rain Homebrew

NABU Discord user “E E Johnson” recently created a really cool Matrix style screen saver called “NABU Digi Rain” and put his open source code up on Github:

Matrix NABU Digi Rain

Features and NABU keyboard control keys:

  • C will toggle chonky or thin font
  • + or – will speed up or slow down the update speed
  • R will reset/clear the screen
  • Pause will of course pause the program

NABU Digi Rain is available as a homebrew .nabu or a CP/M .com file which is awesome! If you have a NABU computer, you should download NABU Digi Rain right away! It runs great on our NABU Network Internet Adapter software and is now available using the NabuNetwork.com v2.0 software located in the Homebrew Software section.

If you have the hardware the F18A builds set a custom colour palette making the dark green darker and replacing white with a very bright green. Currently this feature isn’t supported by emulators like MAME, so you’ll need real hardware to see it.

The random function is originally from Aleksi Eeben’s 1K WHACK for the VIC20. The z80 version used here is from Deep Dungeon Adventure by ARTRAG, John Hassink and Huey of Trilobyte. See random.asm for license information.

The fonts are derived from emutyworks 8x8DotJPFont, which itself is derived from Num Kadoma’s Misaki font. See the font files for license information.

If you’d like to help with the NabuNetwork.com preservation project, feel free to get in touch as we are always looking to improve things around the site. Remember, NABU Forever!!!
