That is _exactly_ my point. 99% != 100%

should I wish to program them using an HP9816, or a PERQ, or a PDP11,
or... then the information is available to do so. I can write a
cross-assembler, debugger, downloader, etc. You may feel that's not a
sensible use of my time, byt darn it this is a hobby, and it is very
difficult to justify time spent on hobbies _other than 'you enjoy doing
But AFAIK the same information is not avaiable for any FPGA or CPLD. You
_have_ to use the mnudactuere's tools running on whatever machine they
tell you you should be using.
