I'd thought of it, but then of course POKE wouldn't accept a linear address 
of sufficient size to 'reach' the memory. As per my other message, I've 
fixed the machine now (bad PCB trace for A11 between slots 3 and 4), but 
your code was still handy because I didn't know that 'DEF SEG=$hxxxx' was a 
thing. I've filed it away in my brain as I'm sure it will be useful again 
one day! :)
