The MicroNova had a floppy drive unit and 10MB removable pack hard drive connected to it but does not appear to contain a dedicated disk I/O controller. The Serial (A-Sync) card in slot 6 is populated with more components than the card in slot 7 and is the most likely candidate for a controller. But this does leave open the question of what the interface protocol is? If it is truly RS-232 style serial this may make it possible to use the drives with any serial equipped PC to dump the data.
