Phil, Thanks for the C4 info. I am trying to find out how Cegmon was normally installed with the FC00 page re mapped to either F4 or F7 I think ?

Are there many of these come up on Ebay.?? Im starting to look here in NZ to see what I can find in garage sales etc... Good luck ...

Steve I saw that for sale Steve and was tempted but the freight looked prohibitive for me. Hope it works for you. By ...
