Yeah, would be extra great to eliminate the 6502 emulation in FPGA, and put a 14Mhz 65816 on the board. There would be a ton of extra gates left (that the 6502 emu took) to add extra hardware, like clock card, echo card, parallel port, serial port, Z80 card, extra RAM, RGB output, etc etc. Rich
I don't think so. I have a serial port and RGB output. There is space left for more hardware if needed.
Now where exacly will the FPGA get the clock info? And the RAM is outside of the FPGA. Internal RAM is used as ROM to hold the monitor, BASIC and cards firmware. So if you use an actual CPU, might as well add
EPROMs, a clock chip etc. Not exactly a system on a chip, is it? :)
