/RAM is the Ram disk. You can install the driver, but since its in Ram, you cant boot from it (since a reboot will clear Ram). But you can boot ProDOS (with NSC installed) from a floppy or harddisk, then switch to /RAM. Saving will save files with a date-stamp, eg:

 

1) Boot a floppy with NSC driver

 

2) Switch to /RAM:

] PREFIX /RAM

 

3) Save file and catalog /RAM:

] SAVE TEST

] CAT
