Known devices

- An I-O Processor
- 6 Teletype scanners
- 14 Teletypes, with behavior similar to JOSS's (with red/black instead of JOSS's red/green)
- A FASTRAND drum at 19.7 million words. This has a geometry of 96-tracks and divided into 54096 50-word sectors.
- 3 line printers
- 12 paper tape punches
- 2 paper tape readers
- Theoretically, network muxes for the IMP interface

The issue provides a device inventory, including the FASTRAND geometry and IMP-interface muxes, but names no file, entry point, or requested change. First clarify where this information belongs and what format is expected; done would require an agreed documentation target and a checked-in representation of the list.
