The Replay Board
The Replay board was designed as a low cost universal development board for running the
*cores provided here. It was time consuming to port the designs to 3rd party reference boards,
many of which had features we didn’t need. The board provides a high quality base platform,
which can be expanded with various daughter boards for specific applications.
One currently in pre-production final testing is the 68060 Daughter Board.
*FPU & MMU maybe or and is Hardware/Software dependant.
A hardware wrapper and flexible firmware support for using cores on this board is provided,
see the Replay Framework page for details. (Currently under redesign).
*Cores for example might include, AmigaOS3.1-3.9 / AtariTOS1-4 or Apple][+/ ZX Spectrum etc.
The Daughter Board
The 68K Daughter board provides a socket for an optional 68060 CPU and expands the Replay
with a second SD card slot, *Ethernet, *USB, and 256MB local/fastram for the 060 plus a real time
clock. It has a Floppy controller, a Midi interface and an Audio in facility for recording/sampling
etc. The Midi interface supports both Midi in and out for synthesizers, sequencers etc.
The CPU can also support a fan if required for higher clock frequencies etc.
The Daughterboard is also designed to be used with other Core’s and Operating systems.
* Record & Sampling will be driver dependent when available on applicable Cores.
It has a 24-bit 96KHz stereo ADC.
* Ethernet consists of a 100Mbit controller. It also has a dual-port USB 2.0/Hi-Speed host controller.
Here’s a list of recommended parts and where to get them. Unfortunately the Replay board is out of stock and discontinued, but fear not, the Replay 2 board is in the making and will hopefully be ready Q1 2018. (This version will also include USB Ports for HID Keyboards & Mice).

Cores for your FPGA Replay
Although this project started out for recreating arcade games, I wondered back in 2003 if it was possible to implement a complete home computer system. The available FPGAs were much smaller in those days, but a complete VIC20 still fit.
Now we have a large number of platforms ported, including 16bit systems such as the Amiga and Atari ST.
The focus is always on implementing the original hardware as accurately as possible, but optional improvements are available too, such as a higher speed CPU, and in the Amiga case more Chip ram, RTG graphics, and modern sound with AHI support.

The Amiga was based on the Motorola 68000 CPU and was sold by Commodore between 1985 and 1994. Its advanced graphics and sound made it popular for gaming and video production.
The Commodore 64 is a computer that was manufactured by Commodore between 1982 and 1994. It was very popular during the 80’s and early 90’s.
