Free: A1200HD/40 w/monitor, software

[SamuraiCrow]

If your monitor is a genuine Commodore monitor, I remember that there were problems with some of them losing their picture after a while of use.  If your A1200 is an NTSC model then you should be able to hook it up to a television the same way that you may have done with your C64 years ago.  Alternatively, you could use the composite connectors to hook it up like a VCR.  If you don't have stereo sound just hook it up to one of the sound jacks and the computer will auto sense mono audio for you.

Also, try holding down both mouse buttons when you start it.  If the screenmode is incompatible with PAL or NTSC then holding down both mouse buttons will let you get to the early-startup menu.  If it has a flickery screen it may be in PAL mode.  If so press space to get it into NTSC mode.

I forgot to mention that the mouse almost always plugs into mouse port 0.  Port 1 is for the joystick.

It sounds to me like it's booting to an incompatible video mode.  Doing the early-startup screen from the TV-set may be enlightening.

Great to hear that it works.  I still have my A1200HD/40 and will be using it for my undergraduate research project on coroutines at the Minnesota State University: Mankato. :-D  I'm glad we can keep another one working.  Are you still planning on posting those pictures?

It's beautiful! :-D

In this picture it looks like it's got an external high-density 1.76 megabyte floppy drive under the other one!  Those are a gem to find, to be certain considering how difficult it is to find medium density 880k (720k PC formatted) floppies nowadays.

-edit- This one is a bit clearer.

It might have taken too long to spin up since it doesn't have Kickstart 3.1 and the delay time on Kickstart 3.0 isn't as long.  It's possible that the hard drive may have crapped out on it, though, since it doesn't show up on the picture with the install screen on it.  (The last picture.)
