Device Acorn BBC Microcomputer Model B (Issue 4)
Keyboard OEM AWC (“Wong’s”)
Switch Futaba simplified linear (“Type 1” keyboard)

This machine was subjected to some very messy upgrades, which started falling apart, and the whole computer has since died. This keyboard uses the same space bar stabiliser arrangement as my loose Type 1 keyboard.
