A project log for AYTABTU - Discrete Computer

After the apocalypse we have to build computers from stuff we can make at home, I.E Transistors, diodes and resistors.

Well, every journey has to have a beginning so I started of with a relatively simple part of the entire system - the UART.

Currently I have the receiver part of the UART working in theory - it's behaves correctly and can decode an incoming character when run in LTspice.

Next steps would be to prototype some parts of it at solderless breadboards followed by making some PCBs for it.

It will be a lot of transistors when the system is done, the total for the UART receiver is as follows (decoupling caps are excluded from the count)

The LSspice files for the UART is available at :
