| Note | The Master Compact, released in September 1986, is built into two units - the main machine and the monitor stand. The monitor stand unit also had the 3.5" floppy drive and PSU for the main machine. The Compact was the first BBC not to have the interface for the cassette filing system (and issuing a *TAPE was ignored). | ||
| Configurations | Of the 128Kb of RAM, 64Kb are the 'main' RAM. The other 64Kb are "Sideways" RAM (four 16Kb pages). The 64Kb of ROM contains the Operating System (32Kb), the BBC BASIC v 4 (1986) (16Kb), and the ADFS (Advanced Disc Filing System) (16Kb) |
