Historical Robotron media — separate from DAC's MIT-licensed work

S550 boot ROM, 287 CAS decoder PROM and TOS/M 1.0 disk image.
Original third-party rights remain with their respective holders. We have
not established a redistribution licence or public-domain status for these
historical binaries. Their availability in an archive is not a licence.
DAC's MIT licence does not apply to these files.

Preservation source: usovmv/robotron-1715m-fpga, Release v0.1:

The manifest records exact source identities, conversions and SHA-256 hashes:

The boot disk is decoded from sw/images/tosm10_orig/A92V010A.TD0.
Do not substitute sw/images/tosm10_x/robotron.img: its PIP.COM is damaged.
No guest patches have been applied. No character ROM is supplied here; the
core's existing fallback glyphs and OS-loaded character data remain in use.
This is a tested historical reference setup, not media dumped from Danila's
physical machine and not proof of its factory-installed OS or ROM revision.

Historical reference firmware, exact specimen revision unverified. Same separate, unestablished redistribution rights as the other historical binaries; not MIT.
