The Amiga RTG GBAPII++ (also written as GBAP II ++) is a Zorro 2-based graphics card designed for classic Amiga computers. Here’s what the name and board stand for:

• GBAPII++ stands for GBA Picasso II Plus Plus.

• • GBA refers to the original designer or project name, often associated with open hardware Amiga projects.
  • PII stands for Picasso II, referencing the well-known Picasso II Amiga graphics card, as the GBAPII++ is designed to be similar in functionality and performance to the Picasso II, though it is not an exact clone and uses a different graphics chip.
  • ++ indicates enhancements or improvements over the original design12.

Key features:

• Based on the Cirrus Logic GD5434 chip
• 2 MB memory
• Zorro 2 bus compatibility (works in Amiga systems with Zorro slots)
• Comparable to the Picasso II in performance
• Open hardware: PCBs can be ordered and assembled by hobbyists
• Sometimes referred to as the A500-GraKa when adapted for the Amiga 500, due to its edge connector option12.

RTG in this context means Retargetable Graphics, a driver standard for Amiga graphics cards that allows the use of higher resolutions and more colors than the original Amiga chipset3.

In summary:
GBAPII++ is an open hardware, Zorro 2 Amiga graphics card inspired by the Picasso II, based on the Cirrus Logic GD5434 chip, and designed to provide affordable RTG graphics for classic Amiga systems12.
