Ah, the 512-byte boot blocks... We got pretty inventive in those days
(and this was before secondary loaders!) with line editing etc.
I was thinking more of the RIM loader on the PDP-8. 16 words or 24

Bah! The RK8E bootloader for OS/8: 2 words... :-)
DPS8-M: 11 36-bit words. Sad. But on the other hand, no actual CPU
