Hello there !
Finally I got my scrap rescued Macintosh Plus alive !
The system start, make 'bong' and then display a floppy with a cross or a question mark if I put a blank floppy in the drive...
From a SE/30 I succesfully make a 800 k 6.0.8 boot floppy. I say "successfully" because the SE/30 can boot without error with this floppy.
Putting this floppy into the Plus and he smile and start to boot... then floppy read, head moves etc... I see the welcome message.
But at some point I get an "illegal instruction" or, less frequently, a "illegal address" error... Then I have to restart the computer.
I have two way to search : bad "reading" from the floppy drive or something wrong into the processor board (rom, ram, etc...).
Because the boot start well my opinion is for the second option...
There is another strange thing. I have try to boot from a external scsi drive (made with the SE/30). After power up I can see activity on the scsi drive but the speaker of the Plus really make strange noises (long krrrrr) and the display become crazy... Nothing readable to the screen at all ! This external scsi drive is working well on the SE/30.
Any advice will be helpfull.
Regards.
Philippe
