emulating an Apple II+ in an FPGA

It's hard to really describe in words how DEEP and vast the FPGA world is. You'd think that learning your HDL is sort of 90% of the work. But it's really not true, learning Verilog is the easy part. :) The hard part is learning how all the tools work together to yield the desired result. I've found that stuff straight-forward as well. Designing for FPGAs definitely takes a different mindset. You don't really write code, you design hardware. Practically everything is concurrent and simultaneous --- so the concept of one instruction after the other simply doesn't exist (for the most part). It's weird to see a block of code that, ummm, is always running. I mean, always there. It's good and it's bad. And your registers are always the exact size you specify --- doesn't matter if it is 3-bits wide or 100 bits wide. And there's no limitations except physical ones..... My current project is going to use picoblaze (8-bit microcontroller core ) with hardware for a timer and time-critical things. Keith
