Must see – Apple Macintosh se/30 TO – Raspberry Pi / Quadra 605 (LC475) / Media display Upgrade
Here is another Macintosh se/30 case modification, this video is part one. This time I’ve installed an iPad 2 display , a raspberry Pi , and a Quada 605 logic-board in the cases. The unit can also be used as a media display via a USB 2 port on the rear.
If you are wondering why I just didn’t install an emulator on the Pi to run the old Mac OS, let me state once again, emulators are not my cup of tea. They are slow, buggy, cannot use the floppy drive, and are a pain to configure for the network. The Quadra (LC 475) board makes it a great little 68LC040 setup.
You can select between the three (Macintosh 605, Raspberry Pi , or display) by using the toggle switch next to the main power switch on the rear. In fact, you must select one of the three options before turning on the main power, as the toggle switch is not DC rated. However it is really robust, and it will withstand selection between the Mac, Display, and Pi, when it is used, BEFORE (sorry for the capital letters) the main power switch is turned on.
The Raspberry Pi is a model 3b with WiFi. The Quadra board has 128mb of RAM, an Ethernet card, and is using a SCSI2SD with a SD card formatted as four 2gb SCSI drives. The Quadra System is 7.5.3, but I will be upgrading that to 8.1 shortly.
The system has three internal speakers, a pair of iMac G3 stereo speakers for the Raspberry Pi and Media Display, and the single original se/30 mono- speaker for the Quadra, but of course, the Quadra can still play stereo out of its port on the rear of the Mac when using external speakers.
Here is a list of the parts I used—
Parts I Made-
1. Power Supply base plate, 16 gauge sheet metal
2. Power supply mounting bracket, 2mm aluminum
3. SCSI2SD activity LED bracket, 2mm aluminum
4. Raspberry Pi mounting bracket, 16 gauge aluminum
5. VGA cable
6. IR sensor bracket, 2mm aluminum
Apple parts-
1. se/30 cases
2. se/30 chassis
3. se/30 Floppy Drive
4. se/30 Power supply housing
5. se/30 -5v circuit from the analog-board
6. se/30 speaker
7. Macintosh II Floppy Drive cable
8. Quadra 605 Logic-board
9. Quadra 605 power connector from the power supply
10. Quadra 605 bottom case that I cut the back plate from.
11. iMac G3 1st generation stereo speakers and cables
12. iMac G3 1st generation Hard Drive tray (for LCD driver-board bracket)
13. iPad 2 LCD, part number LP097X02, with third party driver-board.

7. 5mm female power connector for fan power
8. 3 Pole, double throw, three position power switch AC rated at 15a 380VAC (selector switch, between the Mac, Media center, and R Pi) MUST USE THIS SWITCH BEFORE TURNING ON THE MAIN POWER
9. SCSI2SD version 5.1 with 8gb SD card
10. 32gb SD card for the Raspberry Pi
