-Go to AMORT, TABLE, key in 1 for FIRST, 36 for LAST, 12 for INCR, GO.
-In both cases, what needs to be done is done (but not on the LCD on Plus42, see my previous message);
-Now press EXIT twice, you are back to the TVM menu (second page with P/YR), choose AMORT gain.
- Plus 42 says "#P=1 PMTS: 0-0". Pressing TABLE and GO just prints the variables, no payment;
- The HP-27S prints one paiement (1-1) and only then (why not before ?) says: "#P1=1 PMTS:1-1"

So, in other words, the 27S TABLE menu has defaults FIRST=LAST=INCR=1?

(Plus42 has FIRST=LAST=INCR=0 initially, which is why it doesn't print anything after the header, if you just press GO without setting any parameters.)

Yes.
I think it would actually make more sense to have defaults = previous values, memorize them as long as the TVM variables have not changed, but it seems that it is not how the 27S/17B work.
This is also this issue of printing on the LCD some info about the current set of payments being printed on the printer...
