Ordering NAND pcbs

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.

Instead of trying to wire up dozens upon dozens of NAND gates (which will be by far the most common logic gate in the full design) I routed a small PCB that fits 8 copies of 3-input NAND gates connected to a 4 pin pinheader each. On the PCB there are also common power in & power out connectors .

The PCB is only 20x160 mm (about 3/4 x 6 inch) so they're rather cheap to have made so I ordered 100 pcs of them from Dirtypcbs.

I also ordered a few thousands of transistors and diodes from a local company - I'm sure the parts will arrive long before the PCBs, so I have to start with using my old breadboards :-)
