Just returning back to this, I finally got round to hauling my own 
AKF30 out of the loft and wired up an experimental cable. I don't 
think it's CGA, it's another "standard" I'd not heard of called PGA.

Some rampant Googling forwarded me to this:
   http://project64.c64.org/hw/1084s%20Monitor.txt
which appears to be the same model, however no Analog/TTL switch on 
the back :( Opened it up in case it was just blanked off but although 
there's a PCB presence for it I'm not sure what else is missing, and 
my monitor-fu is not strong enough.

Would still be nice to get it working - the cable gives me the same 
issues Anders had in TTL mode, namely:

...but no analog mode. Is there any way of forcing it into analog 
mode other than soldering a switch up - or does anyone have a service 
manual for this please?
