Took a quick break from the new Replay build system today and tested a batch of replacement 503 ICs. They appear to work well, so I can ship the board back to it's owner and get some desk space back! You can see the new 40 pin module working on the board below....
Finally, after being stuck in Swedish customs for nearly a month (thanks PostNord), the PCB for my 40 pin Konami 503 ASIC replacement has arrived. I'm experimenting with an Atmel 5V CPLD on these, rather than the old Altera MAX7064 which is getting hard to get, and...
The final complete R1 & 68060 DB to ship Well, actually the last (I thought) Replay1 shipped years ago, but I've had one sitting around which failed production test. When a core boots up, the ini file for that core tells the software which files to upload into...

I've released a new version of the Amiga core (svn.fpgaarcade.com). New features : 48M XRAM mapped as Chip and all chipset DMA pointers support 64M addressing (optionally enabled in OSD / .ini file) CPU cache stable - 2 way I + D with full snoop. ~16000 AIBB...
The Replay Board
The Replay board is a high quality base platform for the development and usage of “cores“.
A core can be thought of as a hardware model that closely recreates the hardware of a specific home computer (Amiga, C64…) or arcade machine (Pac-Man, Phoenix…) and runs on the on-board Xilinx FPGA.
Beyond the hardware, the Replay also includes a comprehensive framework library and firmware to aid developers with core implementation and reduces the maintenance burden of supporting future replay hardware versions.
The Replay also provides ample opportunity to expand the hardware with various daughter boards for specific applications such as the 68060 Daughter Board currently in testing.
The Daughter Board
The 68K Daughter board provides a socket for an optional 68060 CPU and 128MB local/fastram for use by the 68060.
A floppy drive can also be attached to the daughter board (for use with supporting cores), making this an ideal upgrade for Amiga / AtariST enthusiasts.
In addition, the board expands the Replay’s I/O capabilities with a second SD card slot (dedicated to the FPGA), *Ethernet and *USB ports, a real time clock, *audio in socket (24-bit 96KHz stereo ADC) and Midi I/O interface.
* Audio In Record & Sampling will be driver and core dependent.
* Ethernet consists of a 100Mbit controller.
* 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.
