Homebrew 16 bit relay computer

The following video shows the calculation of collatz sequence steps by the relay system:

The new wiring of the complete system is finished, first tests look very promising.

This was the old wiring:

So, the next connector is finished, now onto the memory module. This is what the module looked like before:

During the modification:

Unfortunately, a mishap occurred:

Which I had to repair

And now it is finished:

So, the ALU module now has a connector for the data bus and the control lines...

A new video is online, in this video I describe how logic using relays works and how the registers are designed...

So, the first module, the address calculation module, is now finished...I added a plug to connect it with the control unit.

The wiring of the system is a bit messy, as can be seen in the following image:

So, I disconected the modules...

I will rewire the system, and I will use the following connectors for this purpose:

A major success has been achieved...the system test, which thoroughly tests all components of the system, was successfully completed. The following video shows the execution of the test. Phase 1 is now complete, and in Phase 2, the system will be extended with input and output registers.

To be sure that the system is working fine, development of a system test software ist started...the software will test:

a) all CPU-commands

b) the ALU

c) the adress range

The first step is a dynamic generation of a jump table with the subroutines for the three tests and a collection of the results.
