There is an existing 1 MB solution that replaces the on board 4164 RAM with 41256 and adds one 74S153. It installs RAM to banks 0-14. I have done it on my 610 but it is not fully working now. I think this is because i didn't have a 74S153 and used a HCT. Right now I have some 74S153, but I haven't had the time to work on it again. The modification is described in this document: ftp://ftp.musoftware.de/pub/uz/hsg/hsg0.pdf This one is in "german", The phrasing is so bad, even a native german speaker has to read it about three times to fully understand it. I think I will give it a try to translate it. Christian Am 04.05.2012 12:02, schrieb Michał Pleban: > Hello! > > I am developing a 1MB RAM extension for CBM-II computers.
