I ran a DNA synthesis lab for years. Had 4 computers hooked up to oligo synthesizers. I named them Adenine, Cytosine, Guanine, Thymine. My boss hated it, could never figure out which one was which, even tho they had a huge letter written on the front of each one.
All the other ones were functional. HPLC for the HPLC machine, etc.
