Of course, I don't remember exactly which one...
It's the GSF (Good Signal Flip-flop) trimmer (U102) on the Z-axis board (dwg 13). See description of Digitiser Control Logic > Bus Control > Internal Acquire Mode, page 2-61 in my manual (070-2874-01), Jan '82. Also, see Table 2-8 on page 2-122 and are F,G-2 in dwg 21.
