IIRC, The Tube switch on the ABC's keyboard. Whilst it claims to have  
M512 ROMs, when booted it did report itself as an 80286 - sadly it  
only booted up once, and it had been quite messed with when I got it  
(no sound) - I tried the copro board in my ACW with similarly  
depressing results.

Interesting that you have 'some' of these boards, as by all accounts  
the ABC 310 was never really marketed or produced.
