Econet did not; there was no authentication at the network level. Nor could you attach a floppy drive directly to Econet; you'd use a computer (BBC, Master or Archimedes) that had a floppy or (later) hard disk drive attached, running server software, or an Acorn FileStore unit. Some versions of the server software did implment authentication and permissions. ...


Econet networking was first developed for Acorn's System line, which had a 6502 CPU clocked at 1MHz. It was later used in their ARM-based Archimedes machines with 8-25MHz CPUs, as well as the RISC PC line which pushed into the hundreds of MHz. So the system clock clearly doesn't need to be identical for all stations on the network. There is, however, ...


In Econet, using synchronous serial transmission, the sender provides the clock together with the data. The receivers need to synchronize with that clock. And the network clock doesn't (necessarily, although it might be somehow derived from the same clock) need to be connected in any way with the system clock. In the BBC Micro, this clock (and the whole ...


Additionally you had full read/write and execute access on any other station's RAM (including video RAM) if you used assembly language. This is without any authentication required, so there was no security in that aspect.
