1x 22x2 edge connector (main PCB)
1x 10x2 edge connector (main PCB)
2x trimmer (main PCB)
1x 6x2 switches DIP (main PCB)

EPROM 1cen.bin contains the following: "ADAR LTD 1981" at location 0x8FE

On CPUs PCB there is a black epoxy block (DIP40-600mil). No idea of what it is.

update 20151208: redumped EPROM 7cen.bin. It is etched "MM2758A" which according to schematics is an 1Kx8 EPROM, but in reality it is an 2Kx8
