Summary of the RCA Studio IV configurations:


Studio IV system ROM running the built in colour demo.


My own Studio IV SuperChip interpreter! Versions for both PAL and NTSC are included.


3 versions of Tiny BASIC are included:

  1. The original 1978 version, which was recently found at the Hagley Museum and Library.
  2. NTSC 2020 version ported by me from the VIP version. Half of this is based on the 1978 version (initially we only had half) the other half is based on the VIP code with adaptations to run on the Studio IV.
  3. PAL 2020 version, same as above but adapted to run on a PAL Studio IV.
