Can anybody answer my following question?
Does the HP-19C show the next program step (keyboard code) as long as the SST button is hold down like the HP-29C does. Unfortunately I don't have a working HP-19C and cannot test it by myself.

Thank you. Then my emulation does not work correctly yet.

Do you need another go at analysing a 19c?
I finally got a working one a while ago and could pack a parcel again.

Thank you for the offer. My non working HP-19C was already a great help. Meanwhile the SST key hold down does work. If I'm stuck again I will mail you.

Another HP-19C question:
Does the print head advance from right to left or left to right when printing ?
How many lines were printed in TRACE mode when executing a one number function? Are they always two lines? Is there a blank line after the result?

right to left

[INPUT] -> [PRINT]
[9] -> [nothing]
[0] -> [nothing]
[f] -> [nothing]
[sin] -> [90.00] SPACE SPACE [SIN] CR LF [1.00] SPACE SPACE [***] CR LF
[g] -> [nothing]
[sin-1] -> [SIN-1] CR LF [90.00] SPACE SPACE [***] CR LF
[987654321.9] -> [nothing]
[PRX] -> [987654321.9] SPACE SPACE SPACE SPACE SPACE CR LF
[STO] -> [nothing]
[0] -> [STO0] CR LF

nop, look below

there is alway a CR LF at the end of the operation so the print head is ready to print whatever it need to print
paper result (

Code:
90.00 SIN
1.00 ***
SIN-1 // -1 is superscript and takes only one character space
90.00 ***
987654321.9
STO0
// right aligned print head is ready to print

note: all printing is done right to left so what the print head does for the following line
[987654321.9] [PRX] -> SPACE SPACE SPACE SPACE SPACE 9 . 1 2 3 4 5 6 7 8 9 CR LF
edit: typo + add picture + note
Thank you very much Silvain,
Fantastic comprehensive answer!
Right to left was what I assumed and now I can be sure. It explains some behaviour of the microcode. I still have to solve other peculiarities in the printer protocol before there will be the first HP-19C Emulator ever.
