For what it is worth.
I have ported the ciforth model (only 64 bits,the 5.4.0 level) onto
linux running on a riscv, taking advantage from earlier Dutch
implementation of noforth for triecky code words (UMD/MOD).
http://home.hccnet.nl/a.w.m.van.der.horst/lina.html
As usual, all words are extensively tested, all words are documented.

There is I/O for this DongshanNeZha STU board.
Serial port is easily configured to accomodate 31.25 baud (midi)
and manx happily plays the "FIG leaf rag" on my keyboard.

For these single board linux computers (also Orange pi, raspberry pi)
I supply

worddoc({INITIALISATIONS},{MMAP-IO},
 {memory_map_io},
 {},{},{Fills VMA-IO with the memory base address or else an error code.
 forthdefi({DEV-MEM}) has been filled at forthdefi({COLD}).
 If that failed VMA-IO will contains a same negative number,
 that indicates the error.  }

Once you have mapped the io space in virtual space and access it
via VMA-IO, you can apply all knowledge gained from the documentation
of the underlying System On a Chip.
For this particular board the printed circuit layout, the schematics
(9 pages) and a full 1000+ page documentation of the SoC (Allwinner
D1) is available. That is why I bought it.

Sorry, if I had announced this before.
An official announcement has to wait before a burn in period has expired
and I manage to have TICKS available (blocked by really paranoia protection
shit.)
