Our very first (IBM PC compatible) computer in our household was an Olivetti M19. That PC has long since been given away.
Last week, I managed to obtain another M19, with the full 640KB RAM and a 20 MB hard drive.
Unfortunately, the hard drive isn't working anymore and the housing around the keyboard cable is starting to come loose (seems like this is a common problem).
I know that the M19 could be upgraded to also accept an I/O expansion box on the left hand side of the computer that housed a separate PSU and therefore enabled a user to connect a colour monitor to the PC.
Anyone perhaps own an M19 with this I/O expansion box? How do you connect this to the PC and then disable the on-board connection to "tell" it not to use the monochrome monitor with its built-in PSU? I realise you then don't use the monochrome monitor but, I assume there are jumpers that must be changed?
If anyone has one of these I/O. expansion boxes, I would be interested.
