Looking through my stock, I find a bag of 33Ω Russian resistors. The value is a bit weak and there are only 60 of them (the register set has 64 bits)... Time to hit eBay so I can get nicer-looking resistors than the carbon YAGEO 1/2W used for the prototypes. I want to give a crazy, vintage and out-of-this-world look that will stun the novices like the professionals !

After a while though, I start to realise something: why bother with the tolerance? Oh wait, if I bin the relays precisely, then +/-5% resistors will wreck the whole thing...

There are now other approaches:

• Get 1% resistors => more expensive
• Bin the relay with its associated resistor
• Bin the resistors

It will depend on what curious-looking resistors I find...
