Extending and Expanding

So now you have your shiny new LittleSixteen working but you would like to do more with it? Well, here's some things you can do:

Diagnostics

  • If you want to make sure that your machine really works 100%, don't hesitate and just use Rob Clarke's Diag264. You will need to build a test harness, though.

Loading Software

  • The first thing you should get is one of the many SD2IEC variants. Since L16 features C64-like connectors, you no longer need a dedicated version. My favourite one is SD2IEC Pluggable by hackup.
  • The above only emulates a 1541 drive (and not even fully). On the 264 series we had the somewhat faster 1551, which can be emulated with ytmytm's TCBM2SD.
  • For loading software directly from ROMs, you can use my OpenC16Cart.
  • If you need more storage, you can use Marko Šolajić's c264-magic-cart.
  • If you prefer having the original Datassette experience, just use of the many Tapuino variants. Again, you no longer need a dedicated version, so you can use this one, for instance.
  • The above stores TAP files on an SD card. If you prefer using real audio files, you can try MP32C64.
  • Another similar alternative is DatassetteAudioAdapter.
  • You can get pretty much ALL of the existing 264-series software from Plus4World's Archives.

Audio

Tired of TED's sound? Plenty of options!

  • If you have a L16 V3 or earlier, you can add a SID chip with a ReSeed board. This is built-in into V4 and later.
  • Want something like the SFX Sound Expander for the C64? Then get a SoundX. This also gives you a real MIDI I/O interface!
  • Would an 8-bit DAC bring you happiness? You're lucky then, as ReVox is just a click away!

TBD: DigiMoooZ, ReBlast.

Memory

These only apply to V3 and earlier, since V4 already has 512 kB onboard.

  • What about 256 kB? Get a Hannes256.
  • Want even more? Hannes512 will give you 512 kB!
  • Still using V2 and are stuck with 16 kB? Fixteen will get you to 64 kB at least!

ROM

  • OpenRomSwitcher might help you using modern large (E)EPROMs for KERNAL or BASIC on V3 and earlier.

Joystick & Controllers

  • Wanna make a party game? Get up to 8 extra joystick ports with WheelOfJoy.
  • If you would prefer less joysticks but with more buttons, WheelOfJoyMini allows you to connect up 4 extra ones with 2 buttons each.
  • Want even more buttons? Use 2 SNES controllers through NessieSoup.

I/O

  • Fancy a full-fledged RS-232 port? Stop daydreaming and get Plus4Serial.
  • What about a PC-style parallel port? Plus4Parallel is there to help.
  • Need several I/O ports? With Plus4i8255 and an old Intel 8255 chip you get 3.
  • What about an I2C interface? Get Plus42Wire!
  • Still using L16 V3 or earlier and want a User port? Try 16UP!

Misc

  • Wanna make your own custom expansion board? Proto264 might help get you started. TBD: PlusVIA, MultiExpander
