I have seen these Chinese Xilinx FPGA boards on ebay. They seem to be a good deal; however, I think you will need a programming "pod" -- at least $40 (USD).

Having used CPLDs and FPGAs since 1985 (in CUPL, PALASM, ABEL, PHDL, AHDL, VHDL and Verilog), I'm eager to see and learn from your code. Perhaps I can use it to resurrect my first calculator - an HP-25 with a dead ACT chip.

One of my ideas for a future project is making a Woodstock/Spice FPGA core, using a bad HP-34C but with a good key pad and create a desktop version with a bigger display -- a "franken-HP-34C" that is super fast. Nice to think about but probably many months before I could start something like that.
