# Amiga GBA1000 Project

The GB A1000 is a motherboard based on the Amiga 1000. The project was developed by Georg Braun and has the following features (Rev 4):

* CPU: Motorola MC68030 at 40 or 50 MHz

* FPU: Motorola MC68881 or MC68882 at CPU-speed

* RAM: 8 Mbyte 32-bit SRAM, 2 Mbyte ChipRAM

* Chipset: ECS Amiga (ECS-Denise 8373 and Fat Agnus 8372/8375)

* Built-in flicker-fixer with VGA-output

* One Zorro-II slot

* 1 Mbyte Flash-ROM for optional software

* Real-time clock with battery backup

* IDE-controller

* Two Kickstart-sockets

* Fits directly into an original Amiga 1000 case

We only have info and files for Rev 4.

Rev 5 adds a 68040 / 68060 CPU at 50MHz but there are no public schematics for it.

I will attempt to build a GBA1000 this year, this repo will host all the information and research work needed.
