| The monitor was originally mounted in the cabinet
horizontally. Unfortunately, many of my favorite games were
vertical games and would not fit on the screen correctly. Some
of the 'less vertical' games would fit OK like 1943, but the
full 224x288 games like Galaga cut stuff off at the top and
bottom. And to make matters worse, the frequencies used on then
were just slightly different which made it so you had to adjust
the vertical hold to play them and the adjust it back when it
switched back to horizontal. So I decided to try to create a
harness to rotate the monitor. |
| Be advised that this is VERY DIFFICULT. It
took me about a month and a half to do this. It works but it
is not as 'smooth' as I had hoped. There are many factors here....
like that fact that the monitor BARELY fits in the cabinet when
its rotated 45 degrees and that it is heavy and can hold a lot
of voltage. Here is how I did it. This is by no means that only
way to do it. But it works and I'm not going to complain. |

I first constructed a frame that the monitor
would 'ride' in out of two 24" disks of 3/4" plywood.
One mounts in the front and one at the back of the monitor.
The back has two pieces that mount on top, and on bottom of
the rear of the monitor frame. |
| Here are some pictures of the monitor mounted
in the frame, and a close-up of the mounting bracket. There
is also a 2x4 piece that mounts from the front to back pieces
above the monitor, for support that is not shown in the picture. |

 Shelf
supports |
I started by mounting 2x4 supports in the four
corners of the cabinet shelf to provide support for the shelf
and all the supports that were going to be mounted to them.
All the monitor supports are secured to these 2x4's and hold
up the monitor from underneath the shelf. |
Wheel Supports |
The next step was to provide supports that could
hold up the monitor and allow it to rotate. I did this by cutting
a hole in the original shelf that the monitor sat on so that
the bottom rear piece could stick through it with the monitor
resting on the shelf. The plan was to put in the supports with
the shelf still in place then remove the monitor, cut out the
shelf and then replace the monitor. So the monitor was in the
cabinet on the shelf with the bottom rear and front pieces of
the frame attached. I then designed the supports with rollerblade
wheels and attached them to the cabinet. |
| The front wheel supports attached to the shelf
supports and hold up the front of the monitor frame. I attached
2 2x4's from front to back on the sides of the shelf supports
so the rear wheel supports could be mounted to them from each
side. After the wheel supports were mounted in the cabinet under
the edges of the monitor frame, I removed the monitor and cut
out enough of the shelf so that the monitor could rotate. I
ended up cutting a bit of the actual metal frame of the monitor
so that it would fit. If you don't understand any of this just
look at the pictures on the following page. |
