The rom disk arrived quickly, quite difficult to assemble as it is contains a lot of surface mount components but managed and worked first time.
The new RFS monitor and all the included software works well, I even have cpm now! Would be nice to have an 80col screen, is the 40/80 column board going to be released for sale?
I certainly can recommend this board for all MZ-80A owners.

Thank-you, please feel free to report bugs and any new developments (occurring as part of my FusionX project) I will upload to github and send you the flash rom binaries (you will need a compatible programmer such as the TL-866 II to make the update).
The 40/80 column board has been installed in several users machines albeit I havent listed it on Tindie as it requires mainboard changes (removal and socketing of an IC) and quite finicky to install. Having just acquired an MZ-80A with a Kuma 40/80 modification installed I am looking at reverse engineering this mod as it may be more practical to obtain 80 column output, especially if you dont need the external colour output.
