The pattern I mentioned above is what happens when I am running the machine in BASIC 4, running it in BASIC 2 (I think it is) produces this:

SHIFT key pressed stops all keys returning anything except:
@ produces a + and pressing 0.-+ returns graphics

Without SHIFT pressed you get:

QAZ gives WSX with WSX giving WSX
EDC = RFV with RFV = RFV
TGB=YHN and YHN=YHN
and so on

but in BASIC 2 I can press SHIFT and RUN STOP together tp load a programme in from tape
