Well, there is no problems with any of my batteries or the internal power
supply - it all passes the tests in the HMM--so the solution is to replace
the system board (according to HMM). But that is what I want to avoid,
because I can live eith the minor issue of typing the date in at every boot
and just run on wall power.
And, erm, of course the downloaded file creates a bootable floppy...it's
when booting on that floppy and running the program that the error
occurs... ;)
If you do have a system board for the 360C, then I may be interested in
that tho... :)
