The EX5 does not have the signals to correctly control a 27C160 and takes no advantage of the doubled capacity so while they can be used, the OS image needs to be burned into each half of the chip to be sure one is visible to the EX5 under all circumstances. Alternatively, a small mod needs to be done to the chip to ensure that the lower half of the chip is selected by default and the lower half burned.
Thanks for this input. I actually asked Keir from this Amiga forum and he gave me a similar answer.
“M27C160-50F1 is much easier to find. This part is twice the capacity of M27C800, when you program it I recommend you burn each 512kB section twice”
I just have to be a bit more familiar with the “jumper” settings on the adapter to access bank 1 and bank 2 as Keir`s “documentation” is a bit unclear at some points.
Can I damage my device by using a wrong eprom or will it maximum be an error at boot-up?
