Vampire V4 Standalone is an FPGA Amiga-compatible currently in development by Apollo Accelerators. It is built around the Apollo Core 68080 (AC68080) first launched in the V2 line of accelerators, the V500 and V600, which are compatible with the Amiga 500 and Amiga 600, respectively. Although not originally designed as such, the V500 has also been installed in the original Amiga 1000 and Amiga 2000 desktop systems, as these all used the same, socketed version of the original Motorola 68000 processor. While the V2 was only designed as an accelerator, it was equipped with local memory, ethernet, microSD and retargetable graphics (RTG), named "SAGA" or Super-AGA.
