#32523 — Re: Raspberry Pi

If you're looking for a true bare-metal FORTH on the Raspberry Pi, you may be interested in a recent port of jonesforth that removes the dependency on Linux.

OK, that looks interesting, but to avoid the need to buy & keep
new SDs for each such experiment; eg. TinyCore ...etc.,
I wonder if it's possible to 'fix' the SDs MSDOS booter, so that
by just dd-ing a few bytes [via your card-reader], you could
point the <load and run> to various such systems.

I don't expect the following to work, but just as a naive concept:
= if MSDOS booter jumps/starts the 1st-of-4 partitions which is
  marked-as-bootable [needs only 1 byte to be set], the simplistically
  that seems that you could direct the rPi to run different bare-metal
  aps from the same SD. Of course not without 'reprogramming' it.
OTOH perhaps you could use what I've been doing to mark sound-files
with only on on/off-switch: 
FOR i := 1 TO n
  mark the file i;
  Prompt to cutNowFor iMarked;
  restoreFileToDefaultMarking

This would allow the SD to be programmed by the last-set/run ap.
