# zasm and ed from ROM
|
||
|
|
|
||
|
|
SMS' RAM is much tighter than in the RC2014, which makes the idea of loading
|
||
|
|
apps like zasm and ed in memory before using it a bit wasteful. In this recipe,
|
||
|
|
we'll include zasm and ed code directly in the kernel and expose them as shell
|
||
|
|
commands.
|
||
|
|
|
||
|
|
Moreover, we'll carve ourselves a little 1K memory map to put a filesystem in
|
||
|
|
there. This will give us a nice little system that can edit small source files
|
||
|
|
compile them and run them.
|
||
|
|
|
||
|
|
## Gathering parts
|
||
|
|
|
||
|
|
* A SMS that can run Collapse OS.
|
||
|
|
* A [PS/2 keyboard adapter](../kbd/README.md)
