14:57, 5 February 2021 B360K was a famous 3.5" CPC-Floppy format mostly used in germany without any ROM.
Under Basic-Amsdos you had always to start B360K.bas, then you could use your external drive with 80 tracks resulting in 360kB free.
To use the second side of the disk your drive needed a side select switch.
Provided was the Basic-File to use the format under AMSDOS, a b360k.com file to use it under CP/M+ and a program to format a disk using |Format80 on drive B:

The original |B360K RSX was not compatible with other external roms installed. [Shining] has written a ROM-Version, which is compatible to [M4 Board] for example.
