The Computer Wore Pigtails is a series that appeared in the British girls' comic Mandy in 1967, featuring Transy, the “the first computer to look and act like a twelve-year-old schoolgirl” and who is also extremely trans. Her name is Transy, like.
I do not know how many stories there were but Girls Comics of Yesterday suggests that the series was reprinted in 1975 under the title of Electra the Sister with the Transistors between Mandy #462 and Mandy #470 which suggests that there were at least nine. The Bournemouth University UK Comic Database has three stories archived. I have been unable to find any other extant Transy stories, but I would love to read the rest.
Transy lives with Sally Gleade, whose father works at Imperial Transistor Machines (I.T.M.) where Transy was made and is presumably named after. They also attend Leewood School together. In the first story Transy has a problem: She sucks at rounders.

Transy and Sally are taking part in a school-wide competition for the best recorder duet and as such Transy has been a on a diet of music programmes, which are depicted as small circuit boards that she eats.

She wants some more variety, though.

Two other girls in the school overhear how good Transy and Sally are and decide to respond by trying to get her disqualified because “Transy isn’t a real schoolgirl.” Thankfully the headmistress tells them to get fucked.

That plan having failed, one of the girls resorts to violence and pushes Transy into the school swimming pool.

In fairness to her, the idea was just to get Transy’s uniform wet so that she couldn't take part in the competition, but failed to consider the reason why Transy isn't able to swim with the rest of the girls: She is made of metal.

It takes the whole class to haul her out of the pool.

Unfortunately she is totally waterlogged and shut down.


Yeah.

Thankfully the girls are able to drain the water out of her, dry her out with some hairdryers and a classmate named Betty lends Transy her dry uniform for the competition, which her and Sally win.

Next issue: Voice dysphoria.
