Oh come on, man...
I have to hex-edit a copy of disk][ 13-sector ROM, make it read the boot sector, post-nibblize, un-garbage it, and stop the motor. THEN it's readable
And for added crappiness, can't do the un-garbage separately since monitor steps on zero page
All this crap just cause they couldn't fit a 5&3 postnib into 256 bytes. (the 16-sector ROM fits postnib16 into 256) https://mastodon.sdf.org/media/PuFTjMqtXniKNeqLJzM
