[M3devel] How small can Modula-3 runtime be?

[Dragiša Durić]

Theoretically, many things are possible.

But, with great smart cards having 4KB of RAM, and 100+KM of ROM (program memory) I am a bit sceptic here. It's good somebody played with that, but Pascal and Modula-2 are many times more logical choice for really low end hardware. More than enough to talk APDU :).

My interest is DVB receiver. There is usually RAM in tens/hundreds of megabytes and Flash in tens at least. And CPU with MMU, to run decent kernel. Lots of interesting devices, also.

Ever implemented TCP/IP bare bones? My team did, and while interesting project, it's nothing to write home about :).
