After all that, your full fully expanded Amstrad CPC 464 to CPC 6128 spec set-up should look similar like this as shown below: <BR>

Now you have a choice to play games or save / load programs from tape, either 3” or 3.5” discs! As software is concerned, its the same as CPC 6128 with a few add-ons included. <BR>
This idea originally comes from [http://www.obsoletecomputermuseum.org/amstrad/ David Cantrell's CPC 464] at [http://www.obsoletecomputermuseum.org Obsolete Computer Museum] but he didn't write out the instructions how to do it like I did. Its took me months of research to work out how it works on my own CPC 464 one by one and writing it out on rough paper, after I have looked at his web site for the first time and thinking that "Wow! That's what I always wanted on my CPC 464" while I was searching for Amstrad CPC 464 Specs on Internet. Now its here on this web site and I'm very proud that it works perfectly on my expanded CPC 464.<BR>
