So at lunch today, I setup both the Mac Plus and the Mac SE on my desk in the bedroom, this is where I plan to work on them, away from cat supervision.
The Plus does power on, but as I was unpacking boxes, I
found the floppy for it had been removed, the previous owner said it was
bad, so this does not bother me much, although I may put it back in
just test it myself. I also found an Apple 300 external CDROM, I plugged
it into the Mac SE, it powers on and takes discs, but the system did
not see it. All I have is a startup disk rather than the complete
operating system. so it may mean I just need drivers for it.
found an unopened copy of HyperCard, this was an early attempt at a way
to collect and present data, sort of a precursor the the World Wide Web, minus the network support.
I do not know if I have the heart to actually open it and try to use
