If you'd like to buy one, please send me an email with your contact details and I'll email you as soon as I have the next batch of kits ready. You can contact me at oscar.vermeulen on hotmail-dot-com.
(June 2019: After a few months of waiting for new replica switches, I am making PiDP-8 kits again!)
Complete kit: $165.
Assembled & tested: adds $170 plus the cost of the Pi itself. Mind that making the kit yourself may be labour-intensive, but it is very easy: One IC socket, one connector, plus lots of 2-pin leds/resistors/diodes. Not available at the moment due to lack of time, unfortunately.
Shipping: $45 worldwide, with tracking.
Keep in mind:
you will need to provide your own Raspberry Pi (any Pi, except the very oldest Pi's with a 26-pin GPIO port) plus a microSD card. A USB hub is nice to have as an external mount pod to plug in 'paper tapes' and 'diskettes'. The $5 Pi Zero is recommended.
you normally operate the PiDP using your laptop as a terminal, or hook it up to a proper serial terminal of course.
... or build your own
Send the gerber zip file from the download section to a PCB manufacturer, you might want to check with me for any new updates though. I can recommend Seeedstudio and Elecrow as 'known-good'. Furthermore, you need to obtain the parts as listed in the 'Building the Kit' section. Note:
use special extra tall Raspberry Pi connectors if you want to mount a Model 2/3. A 'normal' header is fine for the Model A+ or Zero.
26 switches. You can of course change their PCB footprint in Kicad to accomodate any other type of switch. But with a slight bit of pin bending any small switch will fit.
The acrylic panel is more problematic. You need a provider who prints them at exact 1:1 scale and with exact location. I tried with cheap 'holiday prints on acrylic' type of manufacturers but they rescale and snap off edges. Also, make sure that you order 4 color print with transparent windows (35% shaded ideally). You'll then need to cut out a slot to fit the switches with a router or saw.
A very effective 'budget option': print out the front panel on paper. Laminate it, cut out the switch holes. Sounds ugly, but looks good. The LEDs will shine through the paper.
Get or Build a PiDP-8/I
As of July 2019, 2300 PiDP-8s have been made! You can produce your own at any time from the design files here. However, there are unusually large economies of scale in this project. The cost of the acrylic front panel, for instance, falls dramatically if you buy in quantities. Therefore I also produce the PiDP as a complete kit - until I finally run out of the custom-made switches...
