Upgrading a Microbee PC85 to a PC85b and adding extra Game ROMs.

[Ernest]

Hi Chesh,
The second bank (top 64K are as follows)
ROM E - IC25  Lower = Pak1 - Upper = Pak9
ROM F - IC27  Lower = Pak5 - Upper = Pak13
ROM G - IC24  Lower = Pak2 - Upper is reserved for the PC85b MENU
ROM H - IC23  Lower = Pak3 - Upper = Pak11 
ROM I - IC22   Lower = Pak4 - Upper = Pak12

The ones above are wrong, below is the correct layout.
