Mum had us in the early 80s, so a bit later, but she told me about lots of it.
She did the terry nappies and it was a bit eco thing back then amongst NCT types, which neatly covered up the fact the disposables didn't bloody work anyway. 
She says there was a woman who came to her NCT class who was ashamed about being pregnant over the age of 30 - the midwife sent her there as they were older mums on average.
The health visitor used to calibrate her scales with a bag of flour before weighing us newborns! (You can imagine how inaccurate this is). Mum claims mothers were treated as idiots and she found it very stressful, but knowing my mum I take this with a pinch of salt.
Pregnancy testing was much less advanced. She never had tests in any of her pregnancies, just went along to the GP at about 2-3 months and he agreed she was. She claims also that women who miscarried before then wouldn't necessarily know about it, which strikes me as very implausible really! Anyone know? In fact I don't think she properly believes you can get a positive test before about 8 weeks as she is treats the idea with some scepticism.
She was offered scans with us (elderly primigravida etc.) but refused as they were seen in some circles as likely to be dangerous.
Her GP seems to have done lots of the ante-natal care, and gave her an unofficial sweep 'to see if that gets thing moving' (it did!) when she came in overdue. No monitoring or anything! He turned up in his dressing gown to the hospital, having been phoned he'd know she was having it. This was on a then new-fangled ward that was specifically for low-risk deliveries and not so medicalised, but that GP must have been worked off his feet!
