A $2000 computer, unless it's a notebook, is a pretty fancy system. I saw an
ad on the TV yesterday from a local dealer for a complete Pentium box at just
under a GHz with a large (40GB) HDD, plenty of RAM, USB, modem, ethernet, and
17" monitor for < $600.
Altera and Xilinx have published parallel port JTAG programming interfaces for
their devices.
If you attach the EPROM/EEPROM that contains the
configuration file for an
FPGA to the appropriate pins on the FPGA, it programs itself each time the
power is applied. FPGA's are generally RAM based and "forget" what they
are
when they're powered down. Programming the PROM that configures them is quite
straightforward with nearly any PROM programmer, and the mfg's don't make
requirements for programming them a secret.

Programming most of the logic in 'C' is
pretty well accepted practice since
EPROMS are as big and inexpensive as they are today. Critically timed code
has to be written in assembler, and people often forget that. Many designers
compensate for code that is inefficient, slow, and large, by using a
controller chip that has WAY (20x) more code space and performance than
needed. The coders will use it all.

That is not what I asking for. Once I developed a design (using undefined
software) I don't want have a $2,000 computer running windows 2022 to
re-program my chips from a printer port that developed in 2002 as the
chips only have a 20 year life span, from data files that have been
sitting on a floppy for years.
People like the software for FPGA's and
CPLD's because it's either free or
under $100 US.
It is getting a FPGA programmed that is the problem. I found this out
the hard way, as they don't make under $500 programers for the serial
FPGA proms and very few people even publish a J-TAG interface for a
printer port for the stuff that can be programed that way.
