 Uses old Open ROMs keyboard scanning routine, which is basically example routine by TWW/CTR, hacked to work within Kernal. It's greatest advantage is multi-key rollover, it's disadvantages - it's much less compatible (uses several bytes of memory which are normally free for user software - thus, it is considered legacy for now), does not support all the system variables (`RPTFLG` and `KEYLOG` are unsupported), and ignores the configuration options - this can be changed, but it requires some effort.
 
-Needs 70-250 more space in KERNAL segment (depending on the features enabled for current default routine). If unsure - disable.
