BBC Master problem

[10walkham]

Hi All

Could anyone be kind enough to provide me with suggestions for this problem:

When my friend turns on his BBC master he gets the following text :

Acorn MOS
Searching
bad command
this is not a language

Thanks in advance

Liam

See Sprow's website:

You may also need to replace the battery pack inside the Master:

However I'm not sure why "Searching" and "Bad command" shows up. It would suggest the computer actually found a language ROM but gave up after a while.

Good luck!
