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
bytes.

Bah! The RK8E bootloader for OS/8: 2 words... :-)


DPS8-M: 11 36-bit words. Sad. But on the other hand, no actual CPU instructions. All addresses and Channel Control Words and Data.
