The AMRAM has two PCBs sitting on top of each other, joined with a rigid connector.
On the bottom is passthrough for other expansion connectors and a 3V square lithium battery.(The exact replacement battery is expensive. It *is* possible to fit a PC CMOS compatible lithium battery and holder, but it's not as neat and there is not a lot of space between the two pcb boards of the Amram)
On the top, 32K RAM (contents are held by lithium battery so can survive a reset or power off), which can be programmed like ROM and occupies two ROM positions (1 and 2) and also sockets for expansion ROMs up to ROM 7.
There is a bank of DIP switches to enable/disable ROM slots, a switch to enable/disable writes to 32K RAM (left side of top pcb), a LED to indicate RAM is ready to write and a switch to reset computer (right side of top pcb).
It seems the first few batches of these were distributed without boxes, so you had to provide your own because the . A suitable box I have with mine is home can be madefrom a "General purpose ABS Enclosure" which is a black plastic box designed for electronics. This is the type of box shown in the picture.
Came with software to program it.
