This explains your memory issues. These instructions should not be entered as an Alpha, but with the printer attached and with XEQ "ACA" and XEQ "PRBUF".

Do you really think he entered these lines als alpha strings ?-)

James: how did you enter these lines? You have to have a printer connected and then type [XEQ] [ALPHA] ACA [ALPHA]. Only program lines enclosed in quotation marks "" are alpha text. Here is a test: Now that you have entered the complete program, run it with [XEQ] 44. What happens? Do you get a NONEXISTENT error? If not, press the ALPHA key to look at the alpha register. What do you see there? "============" or "PRBUF"?

Anyway: even if these two commands were entered as text this would not explain the missing 19 data registers. So there must be something else going on here. Howver, if James really entered every command that is not on the keyboard as alpha text... but since he owns two HP41s I cannot imagine he does not know such basics. But maybe he forgot after some decades without using these devices....?
