An adapter to use up to two standard Atari joysticks with the Dragon.
The board uses four PNP transistors marked “B1014”, which correspond to 2SB1014 (Japanese PNP small‑signal transistor, TO‑92). Pinout (flat side facing, leads down): E–B–C. As the original part is discontinued, a 2SA1015 or a general‑purpose PNP (e.g. 2N3906, BC557) with matching pinout and similar ratings (−50 V, −150 mA, hFE ≈ 100–320) may be used.
