Abstract: An extremely short (12₁₀ instructions) toggled bootstrap for

a Sykes 7100 disk system is presented. This bootstrap reads disk-resident

code, prestored in a 6 + 6-bit format which overwrites the toggled code

and then takes over. The resident code has room for up to 86₁₀ user-

written instructions which are used to load an appropriate disk handler.

Also provided is the program needed to prestore this code in the required

format on track 0 of the disk.
