Try as I might, I got about 95% working but the Bond/Note calculations as described in the manual and applications manual are not making any sense to me and I cannot get them to work.

As I am not much of a financial wizard, I think I failed on this one

Tony, thanks for doing this. If you give me the page number of the manual where you are stuck, and the specifics, I'll be happy to take a look and see if i can help. No guarantee, but I'll try.

Just the formulas on pages 113 and 114, specifically the definitions for E and N

an example from the HP-92 applications book Pg 85 - a bond settlement date is 9/17/1976, maturity date is 12/15/1976

(from 1st formula Pg 113)
N - doesn't look to be used in the case, although its definition seems a bit vague, whole periods, fractions of periods
E - is used, days in coupon period before settlement
coupon = 6 month, 12 month assumptions ??
I assume the entire bond period in this case??
If it is the days between the last coupon period start and bond settlement.
When does a coupon period end?

DIM/b - is that DIM divided by b (basis Switch) or just that DIM relates to a 360 or 365 "days between" value.

Accrued Interest is also included in the answer, but no mention of the method involved, I assume just coupon interest divided by the days in question.

I have been asked to do night survey flying in pitch black conditions in very remote areas next week, so I will have to focus on that as it is risky. If I get time (and internet) I will try to do some study into bonds which may reveal some more clues.

cheers
