The very talented Arnim Laeuger has been working with our new Replay framework to bring his games to the Arudino Vidor 4000 FPGA platform (called V4 from here down)
The Vidor is a low cost FPGA board available here : https://store.arduino.cc/mkr-vidor-4000
To support the cores, the firmware which runs on the Replay1 board ARM can now be built for the SAMD21 within...
Coming from an ASIC background, I generally don't use the FPGA tool IDEs. Sure they have a place for debug, but for consistency especially when using source control systems, scripting is the way forward. Both Intel and Xilinx have good support for TCL in their tool chains, but I find this a bit cumbersome.
I've built a set of python scripts...
I made some comments in a post here regarding FPGA selection for Replay2

One of the reasons we have been targeting the Arduino Vidor board is to get a low-cost alternative for Replay1 for people to play with - that is actually available. The other reason was to force the restructure of our code and build a system where we could...
Here "Erique" the world renowned Amiga demo coder is doing some actual hardware debug. I think he got a bit over excited if I'm honest....
The Vidor currently has some limitations with it's USB OTG support, primarily connecting a hub doesn't work. This is rather useful if you want to connect both a keyboard and mouse simultaneously.
A parallel track is to...
We've sold all the boards in Europe. Jim Drew still has one or two in the US which can be shipped anywhere.
If you have a Replay1 board, this is your last change to get one! Ping me or Jim.
Cheers,
Mike...
I have an original Replay1a board back for repair at the moment, so I thought I would take a picture of the family together.
R1a on the left. R1b next with the 68060 daughter board.
Top right the Arduino MKRVidor4000 we are targeting to be a low cost R1 replacement.
Bottom right the Zynq Ultrascale board which we are using to evaluating the...
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. I've got some left in stock, contact me if...
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 rather expensive. The PCB is double sided with a nearly solid ground plane on...
