This is not needed, and it will not work with a RAM module. If these nibbles are zero, the RAM will be used back as main memory and the port content will be lost at the next HP-71B turn-on. Actually, this is why ROMCOPY is setting these nibbles.

I'm assuming you are now too much FRAM71-oriented :-)
