I didn't think I would have time to work on this in 2011 but I spent a lot of time on it in the past few days. I'm currently working with a MV1B running a unibios 2.3.
So far I have a fully working memory card proto board that I can move between systems - AES or MVS. For all AES and the 6, 4, 2 and several 1 slots it works fine. On the MV1B I have the system seeing that the hardware is installed, card detect is working but it doesn't fully read the card properly. When you finish a game it will ask if you wish to save, if you select yes it will try and give an error.
At first I thought this project only required CE, WE and OE to be found, sadly we also need CD1, CD2 and WP. I've found CD1, CD2 and WP which is why the system is able to see the card.
I know for sure now that this mod can be done. I'm not sure how long it will take to complete but I will finish it. When I finish the mod the new board will require you to install a new bios socket plus 6 surface mount wires.
More to come!
