Hi,
I'm currently trying to start one of my M40s for the first time since
over 5 years, and it doesn't boot.
I had the 8" floppy drive removed in order to image the floppies on
a PC.
Now I've put it back into the M40.
But it doesn't boot anymore, it just says 3 numbers: "4 5 8".
I assume these are indicators of failed startup tests, but I cannot find
information about what these numbers actually mean.
Does anyone here have some documentation about the M40,
most preferably hardware documentation or a service manual?
Any help would be appreciated.
regards,
chris
