[comp.sys.acorn] A310/Large OS chips

On the question of the large OS chips for A310 and I guess A305 machines...

The problem with them is not that the sockets are not large enough. If you
take a close look you'll see the chips don't use all the pins on the sockets.

However, Acorn decided to wire these extra pins to +5volts - thus rendering
them useless as possible address pins.

I don't know how the IFEL 4Meg board and other's like it intend to overcome
this problem - anyone with this knowledge care to answer?
