Master 512
Getting Started

The Tube is activated and we get the new start up message telling us we have an 80186 co-processor and 512K RAM.

Actually, you are unlikely to see this screen without some deft fingerwork. You have to press CTRL-BREAK followed by a very rapid F-BREAk to bring up the supervisor prompt, otherwise the 80186 boot sequence attempts to mount disc drive 0 to load the DOS Plus operating system.
