I have a short story too (see below the oath quote). It does not include women because the oath text does not either. You can rewrite it to include gender mechanics (making the patient a woman, perhaps) but it’s probably not worth the effort. For starters, appendoctomy hadn’t been invented back then.
“Could I fuck a female doctor instead?”
“To my knowledge, there aren’t any in all of Pelopones. There is quite a selection of gay men, though. A nearby one is crossdressing, actually.”
In almost all microwaves, the control circuitry or mechanical switches only ever switch 2-3 power circuits: motor+fan(+bulb sometimes separately) and the heating (transformer+diode+capacitor+magnetron) high voltage circuit. It can therefore only switch the heat between 0 and max, usually in a slow (15-30s period) PWM cycle (that hopefully does not coincide with the tray rotation period). The inputs can be manual only, or sometimes there is also a scale, moisture sensor and microphone, along with thermal fuses for safety.
I think the pizza setting is just generic medium one with short 50% cycles to allow the heat to spread. The popcorn setting can be much more interesting:
