What are we going to do? We're going to punch in a binary program to handle that
kind of reception! You're gonna feel real badass about it too...

If everything went well, you can run Collapse OS with `g3000<return>`. You'll
get a usable Collapse OS prompt!
Like with the `recv` program, nothing stops you from dumping that binary to a
floppy.
## Saving to disk
You could save your sent content as-is by following the instructions you had
for the `RECV` program, but that would mean that your executable would boostrap
itself every time it starts, which takes multiple seconds. You're better off
saving a compiled version of Collapse OS, something you already have once you
see the "ok" after running `g3000<return>`.
Before you do that, however, you need to update your `LATEST` field, something
you can do with `CURRENT @ 0x08 BIN+ !`. You also need to know where your
binary stops, something you'll get with `H@ .X`.
Then, you can go back to TRSDOS with the BREAK key followed by `o<return>` and
proceed with writing the proper memory area to disk.
TODO: make this work. this doesn't actually work. Saving it before compilation
works though.
## Configuration
