Used by the routine at BootstrapEntry.

Stage-2 Micromega 1.1 loader. It first checksums itself, then reads a 16-byte custom header that names destination 4000, total length A81D and 0C overlapping chunks. Each of the twelve main chunks carries 0DB6 tape bytes but only advances the destination by 0DAC, so the last ten bytes of one chunk overlap the next. A short final chunk finishes the A81D-byte main image at Loading..E81C, which overwrites the REM bootstrap. Control then returns to BASIC so line 4 can ROM-load the final support block on top of this loader.

While the chunks load, TimingSwitch alternates two timing-parameter sets and TimingPatchCopier patches them into the sampler at TapeSampler.
