I found out what was going on here. A medium-sized story, but...

I'm using a 16K image in a 32K EPROM. I used the EPROM programmer's own 
buffer editor to change the bytes.

Now here's the thing. When you load in a 16K image for a 32K EPROM, the 
programmer software "doubles up", and loads the image into both halves 
of a 32K buffer.

When I edited the buffer, I only changed the values in the lower half. 
Stuck the chip in the socket, and of course the circuit wiring makes the 
top half available, or at least at the highest priority, which is still 
set to 254/235.

I have now bent up A14 and connected it to GND to force the lower half. 
Works fine now :)
