I looked up their website and cant find much about the Amiga, just stupid rubbish like the crappy Vic20, Philips Videopac etc...
You have to remember that the FPGA Arcade is not just for Amiga use, but alos for "rubbishy crap" like the VIC-20, Atari ST, orginal game consoles, etc.
Here's the main board:
http://www.fpgaarcade.com/common/replay_overview.jpgFrom the Amiga side you have:
2 x Joystick ports
2 x PS/2 connectors (mouse & keyboard)
SVHS Out
Composite Out
DVI Out (DVI to VGA via cable)
Sereo audio out (3.5mm jack)
SD Card (store FPGA updates, cores, ADF and HDF files)
Reset button
Daughterboard expansion (like the slot on an A500/A600/A1200)
DDR2 RAM (fancy 48MB of Chip RAM to go with your FAST RAM?)
Serial port
5 Power inputs (take your choice of which one you want to use)
On/Off switch
Spare I/O connectors
Current core:
Switch between 68000 and 68020 CPUs
Up to 4x Floppy drives (normal and fast modes available)
Up to 2x Hard Drives (HDF files)
Kickstart selection via menu (1.3, 3.0, 3.1, etc)
OCS, ECS or AGA chipsets
RAM user configurable (set how much Chip, Slow, Fast, etc you want)
P96 RTG to be included in update.
I'm sure I've missed something, and I haven't even mentioned the daughterboard yet. ;-)
