I don't know whether you have particularly strong

including both bottom-end parts in the sub-$30 range and top-end just-released
OMFG-that's-expensive stuff. I tend to be biased towards Xilinx FPGAs since
they're what I have the most experience with.
The intersection of microcontroller, FPGA and implementation language on cctlk seems to be
the null set.
I had been tinkering with Cyclone parts, but most people here use Xilinx. I think Verilog
vs VHDL is about half and half.
Over Christmas, I bought myself a Pipistrello board with level converter shield

To use as the capture part of the DECtape reader prototype (easier than dragging one of my
16500Bs into work).
Using the OpenBench Logic Sniffer 64MB port

As you say, as the parts have become cheaper, non synthesized CPUs are becoming less
interesting. I had hoped to split the
custom things that I needed to do into the FPGA, and leverage the jellybean stuff to the
microcontroller where I have more
experience and there should be more running code available (assuming you can pull the
toolchain together and have it work
with the code that's out there).
