Not vintage, but closely related.
Rather than write some emulation software, I'd like to see if I can
implement some simpler CPU designs in FPGA.
I see various development kits out there with various capabilities
(I/O memory, displays, etc.).
Is there any particular kit that stands heads and shoulders above the
others? Is there a preference between Xilinx and Altera?
I'm just looking for some pointers here.
Thanks,

There are many board vendors. Most are listed here:

This type of stuff is regularly discussed in comp.arch.fpga
The web site http://fpgacpu.org/ is a somewhat dated collection of related
material, but importantly includes the three articles from Jan Gray that
were published in Circuit Cellar in 2000:

There is also a Yahoo group, but it is pretty dead.
The first CPU in an FPGA was designed by me in 1990, The RISC4005/R16.
It had flashing lights and paddle switches just like any other REAL computer.
The architecture was a 16 bit that looked a bit like the AMD29000 RISC.
Does it now rate as classic ? :-)

Philip
