Zellweger Uster TCA-C

These two cards contains the CPU(Intel 8085) and RAM, respectively.
The CPU card have 4 x 2732 EPROMs(4KB each) and some support chips.
The RAM card contains another 4 x 2732 EPROMs, in addition to 6 x 4118(1KB) RAM chips. There's also sockets for another 6 RAM chips.

It may be possible to use larger RAM/EPROM chips as the sockets are physically larger, but without documentation, I do not want to experimant.

TCA-C Telephone Call Analyser

I really wish I knew more about this piece of equipment.

The date is a guess based on some stickers on modules inside the unit. The RAM amount is based on the fact that I found 6 x 4118P (1KB) RAM chips on one module. Strangely enough, I didn't see any RAM on the CPU card.
