I'm putting some thought into installing an auto pilot in my M5-235. What's legal? S-Tec 20 & 30?

From the Maule Optional Equipment index on their website:

E. AUTO FLIGHT SYSTEMS (AUTOPILOTS) 1. Century Flight Systems a. 9074E Century IIB/AK 513 10.6 7.8 b. 9142E Century 21/AK 932 13.4 7.8 2. S-Tec Corporation a. 9193A System 40 (14v system) (ST-418) b. 9193A System 50 (14v system) (ST-418) c. 9195A System 55 (14v system) (ST-573) d. 9196A System 55 (14v system) (ST-620) e. 9197A System 20/30 (14v system) (ST-810) f. 9200A System 40 (28v system) (ST-609) g. 9200A System 50 (28v system) (ST-609) h. 9201A System 20 (28v system) (ST-820) i. 9211A System 20/30 (28v system) (ST-872) j. 9212A System 20/30 (14/28v system) (ST-873) k. 9223A System 55X (28v system) (ST-890) l. 9235A System 60 (28v system) (ST-495)

Kind of hard to read since it didn’t index properly, but basically Century 2B & 21 or pretty much everything S-Tec makes.
