Step 8: Switches and ports.
Front connectionsI decided to add two front USB ports, and an SD memory card reader.
I cut a few sections of styrene to fit, and clip into the front of the metal frame where the original ADB and floppy connections were.
Once you have mounted these two sections (one shown upper, the other just underneath) slot the frame into the casing, once inside you can carefully trace through the gaps to get an accurate placement of the ports.
At this point the dremel is very handy for drilling out the holes to position the ports.
Once you have the ports in place you can assemble and check the position again. Use some epoxy resin to glue these in place.
Rear Ports and switch.The original macintosh had a power switch at the back, most modern computers have switch on the front hooked up to the motherboard. The original macintosh did however have a 'reset' and 'interrupt' switch to the side.
I created a small L shaped section for the rear ports. On the side of this I mounted the power and reset switches. Once the L shaped section was placed into the case I then inserted the original buttons (a plastic section that fitted into the vents at the side), once these were inserted it made it very easy to glue the switches into the correct place. Check the original plastic depresses enough to click the new switches.
I went to great efforts to make the CRT and front of the screen look original so decided to extend this effort to the back.
When fiddling around with various bits and pieces I worked out that the USB extension cables fittied inside the metal surrounds of the old Serial connectors perfectly.
I placed the L shaped section against the back and marked out the various port holes. Using the dremel I was easily able to cut out sections to allow the USB extension cables to meet up with the metal off the serial connectors.
Once these are lined up use both epoxy resin, and a hot glue gun to secure these in place.
I also added an ethernet port to align with a hole above the power connection.
