Now in stock : PiSCSI Housing for building a external SCSI emulator based on a Pi
After i sold a few kits and assembled external PiSCSI (RaSCSI) sets, i started to think that it would be neater (and safer) if the Raspberri Pi and the PiSCSI tht wouldn't be out in the open.
So i started to design a PiSCSI Housing to complement my version of the PiSCSI (RaSCSI).
The design is based on a PiSCSI hat with a Raspberry Pi 3A+, but it would most likely work also with the smaller zero versions of the Pi.
Compatibility PiSCSI Housing and Raspberry Pi's
Like i already stated , the design of the housing was based on the combination of a PiSCSI in combination with a Raspberry Pi 3A+.
The PiSCSI hat will stay on the same location, so the opening for external power will stay at the same spot (As long as you don't use GPIO extensions of any kind)
On the Left side there's a smell opening for the Micro SD card (you'll need pliers to insert or withdraw the SD card)
Front side has an opening dor the Female DB-25, so you can connect the PiSCSI device easily to any host.
Compatibility PiSCSI Housing and Raspberry Pi's (Cont.)
On the Right side there's an opening for the USB Port of the Raspberry Pi 3A+ which allows you to insert a usb stick if needed.
On top of that opening is a opening for a Berg connector, which allows you to externally power the PiSCSI.
If specifically stated when ordered i could leave out the Berg connector and opening and use the internal 5 volts header to supply power via a standard DC barrel connector.
Mounting the Raspberry Pi in the PiSCSI Housing
If you are using the Raspberry Pi 3A+ , you can secure the raspberry on all 4 holes of the RPi 3A+ PCB
Screwsholes are on the bottom side of the housing, allowing you to screw them into the spacer nuts of the Rpi.
The PiSCSI hat will be connected to the Rpi , secured with 2 screws into the same spacer nuts.
The front side of the PiSCSI hat rests on 2 supports inside the housing.
if using a zero , only the back 2 holes can be used to secure the RPi , but that should still be enough since the PiSCSI hat will be supported on 4 spots.
Many thanks to A.kuker , for not only creating this fantastic interface,
But also providing enough info to let me design my own version of the PiSCSI hat.

I built the XL kit to use for Macintosh SE/30 and Classic II. Simple and enjoyable to build, it worked well straight away, and the sockets in the XL kit are nice to avoid mistakes.
I used a Raspberry Pi 2B and placed the PiSCSI image on it and configured it via the web interface on the ethernet connector. The DB25 connector matches that of the Macintoshes, so a 'straight' DB25 male-male cable works fine for external use. Starting up the Raspberry Pi is not very fast, but after that it works smoothly and comfortably on the old Macs. Great for breathing new life into old classic Macs.
Translated review from the Dutch Website : Ik heb de XL kit opgebouwd om te gebruiken voor Macintosh SE/30 en Classic II. Eenvoudig en plezierig om op te bouwen, het werkte meteen goed, en de sockets in de XL kit zijn prettig om fouten te voorkomen. <br />Ik heb een Raspberry Pi 2B gebruikt en daar de PiSCSI image op gezet en geconfigureerd via webinterface op de ethernet connector. De DB25 connector matched met die van de Macintoshes, dus een 'rechte' DB25 male-male kabel werkt prima voor extern gebruik. Opstarten van de Raspberry Pi gaat niet heel snel maar daarna werkt het vlot en comfortabel op de oude Macs. Prima dus om oude klassieke Macs weer nieuw leven in te blazen.
I used the RaSCSI Standard Kit. And indeed DIP solder is a lot easier than SMD ;-). Included good instructions for use.
I have a Pi Zero II and it actually works very well
Point of attention: The Acorn boots up faster than the Pi-Zero, so wait a moment or press Crtl-Reset.
