Front of the DECserver 90M
Side 1 (or top?) showing the 10base2 connector. This would be the right side of the module if installed in a DEChub 90 Ethernet Backplane.

The back. The mini-DIN connector is for powering the device in a desktop configuration. The white connector provides power and Ethernet when installed in a DEChub 90.
The plastic ring fits around the 10base2 connector on the side. The screw fits into the back to hold the PCB in place.
The front bit of plastic
This label was floating around inside the case. What it was originally attached to is unknown. The part number stated on it is "74-46799-02 A01 PPI" - maybe Google will lead someone here who knows what it is off.
The inside of the case. Also visible is the unknown part number label, and the front plastic bit.
The DECserver 90M PCB. The module installed in the upper right corner appears to contain flash memory.
A module that appears to contain flash memory. It plugs into the DECserver 90M PCB in the rear right corner. Its numbers are: AS45201712, C02, A1 L4 5022854. A picture of the other side is also available.
The back of the module. The chips are AM28F020 - 2 Megabit (256 K x 8-Bit) Flash Memory. The front of the DECserver 90M claims 1MB of Flash Memory and there are 4* 256K Flash Memory chips here - 1MB.
