There are FPGA implementations of the 6502 out there. If you've not seen
it, check out the MiSTer[0] project, FPGA implementations of a LOT of
computers, going back as far as the EDSAC, PDP-1, a LOT of 8, 16, and 32
bit systems from the 70s and 80s along with gaming consoles from the 70s
and 80s.
Keeping this semi-TUHS related, one guy[1] has even implemented a
Sparc 32m[2] (I think maybe an SS10), which boots SunOS 4, 5, Linux,
NetBSD, and even the Sparc version of NeXTSTEP, but it's not part of the
"official" MiSTer bits (yet?).
