I had nothing to do with this port :-)

I left 16-bit for new projects +/- 1997 when I started with FPC, and ported all remaining stuff to it in 2000. (mostly because I started using Windows NT/2000 at work, and soon after at home too). I kept a 386 mobo for a while for minimalistic stuff, but as hardware started to pile up, I got rid of it.

Note that it is all still very initial, and I haven't heard the exact plans (asked for rationale, Nikolay said "because I can"). E.g. how many TP idiosyncrasies (think inline($54) etc) are going to be implemented.

Self hosting (16-bit compiler that generates 16-it programs) is probably out of the question. (at least if I my memory is correct and 286pm only does 16MB max) So probably it will always be (64/)32-bit -> 16-bit crosscompile.

Yesterday hello world (and thus the whole RTL startup) ran on a 80186 (LX200 iirc)
