This leads me to a question. Like everyone and his brother,
i have a lot of CPUs laying around, non of which is a Risc
or a Misc CPU, and surely no stack machines. So i'm writing
my own Forth dialect and gonna implement it on the various
platforms (some PCs, an RCX (H8 CPU, AFAIK register-based)
and maybe a Gameboy Color(Z80 lookalike)). 
And if i'm good, i'll get a performance 
of about 1 Forth instruction per 10 machine instructions.

So, if there would be some cheap board with a Misc or Stack
based CPU, or some consumer product i can rip such a beast
off, i'd expect a much better match to the language. Is
there really no such CPU on the market? I can make my own
board if necessary, so the chip would suffice. Does anyone 
here have pointers? I can't spend a fortune, so it must be
cost effective. Hobby for now. Maybe an FPGA based design.
But looking on sites like opencores.org or how they're called,
it looks like there's nothing Misc-like on the "GPLed hardware"
design front at the moment. They seem to be busy cloning
industrial cores like the ARM, using a whopping 22K gates
for a CPU core. That's not what i'm seeking.

Anybody here who got a Misc design working at home, be it a
stock CPU, an FPGA or whatever without being a full time
chip designer?

And is iTVc still in operation?
