HP-67 Card Operation Query

[teenix]

Hi All,

Can anyone help with a spare few moments and a working HP67 card reader?

While a program is running, you can position a card in the card reader slot ready to start reading during a Pause instruction. The motor switch will be tripped, but because the program is running it will be ignored until the Pause instruction executes.

I was playing with the 67 emulator and if I write a simple loop program like...

LBL A
7
Enter
Add
GTO A

If I press R/S to halt the program, the card is read into memory.

Just trying to find out if this is how a real 67 works?

cheers

Tony
