The finished product.

The rear of the unit. Connectors are for audio, ethernet and keyboard. If you look closely you'll notice a lot of scratch marks where the big information label used to be. That label was insanely difficult to remove. Had I known it was made of some kind of ultra-sticky gelatine crap I would have just painted over it.

Close-up of the front panel controls. The buttons are made from LEDs and ones in a row to the left light up when active.

Four screws (+ two for the knobs) out and the front panel comes off to expose....lots of LEDs on poles!!!

This is no normal Macintosh....

Analog board removed. There's space for another hard drive in the bracket...

The thing the boards are slotted into is actually a cut up chunk of old motherboard with all the ICs and resistors ripped off.

The PCB was really rushed, anything I wasn't sure about at he time I just left out. So, as you can see, it required a lot additions. The rotary encoders are mounted with roller door bearings. They're packed with heavy grease that gives the encoders a very smooth feel while turning.

Insert motherboard here. One edge of the board sits between the original logic board and the paddle pop stick. The other end is held in place by two screws into the chassis. I was also going to tie it in with wire/string but this seems to be good enough.

Testing.

Video card. Quad AND gate and a 22MHz oscillator (made with a cmos quad NAND gate) are visible.

The 486 motherboard. The power regulator's heatsink has been upgraded a bit.

The back shells of these things are coated in conductive paint, better than metal shielding I suppose. The PCB to the left is the Macintosh sound generator. It plays the distinctive compact mac startup sound through the original speaker when the player is switched on.

Screenshot. Not a very good photo - it's difficult to photograph bright text without obscuring it a bit.
