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 16384, total length 43037 and 12 overlapping chunks. Each of the twelve main chunks carries 3510 tape bytes but only advances the destination by 3500, so the last ten bytes of one chunk overlap the next. A short final chunk finishes the 43037-byte main image at Loading..59420, 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.
