Description
TL;DR: A researched link pack for the DEC VT-180 “Robin” CP/M system, centered on the surviving BIOS and boot-track source.
The VT-180 was DEC’s CP/M-capable extension of the VT-100 terminal. Useful documentation for it is scattered across old personal collections and preserved copies of long-lived technical sites. This product collects the relevant locations from one surviving DEC reference page so you do not have to reconstruct the trail yourself.

Why this set matters
The small BIOS archive is the interesting piece: it preserves assembly source for the VT-180 CP/M BIOS and boot track. The machine-specific manuals provide the hardware and service context needed to make sense of that source, while the CP/M and Z80 manuals cover the operating-system and CPU environment around it.
Known limitation
The BIOS source references a DISKDEF macro library that is not included in the identified VT-180 source archive. This product should therefore be treated as a researched preservation/reference set, not a guaranteed complete build environment.
What you are buying
CacheRat provides the research, identification, organization and verified source locations. The underlying third-party documents and source files remain at their preserved locations; CacheRat does not claim ownership of them.
External preservation links can change or disappear over time. Recheck availability after purchase if a host later moves a capture.
