What are the power requirements for the board including the 060 expansion?
The board is powered only from +5V power rail. The peak power consumption is:
FPGA Arcade alone : 700mA (3.5W)
FPGA Arcade + 060@106MHz : 2.2A (11W)
On the daughterboard there are 3 USB host ports which can sink up to 0.5A each. So you need another 7.5W for USB devices which gives 18.5W in total.
Another question: Will I need a fan?
Running the 060 at over 100 MHz makes it quite hot. A fan is necessary. If you decrease clock frequency to 80-90 MHz it can run with passive cooling.
Can one also split it up, for example 12MB of CHIP RAM and 36MB FAST RAM?
I'm not going to implement any other memory configs. Why do you need this?
How is speed of CHIP RAM, SLOW RAM and ZORRO II FAST compared to FAST RAM on FPGA-arcade?
Excluding Fast RAM on the daughterboard all the other memory has the same access speed. The maximum transfer rate is 28MB/s but it depends on DMA load.
