About the HP71B, I asked a few questions to Doc. Mike Meyer a couple of days ago and I was told that the same AC adapter used by the topcats (HP9x), HPIL printer and tape driver, HP9114B and HP82143A (HP41 printer) can be used with it. I tested and it works fine.
I am using four AAA NiCads with mine and I was also told by Doc. Mike Meyer that the HP71B cannot charge batteries. The AC adapter works the same way that the AC adapter for the HP82240A/B: it feeds part of the power, but cannot charge batteries. Kind of "power support".
If you have the MoHPC CD pack, have a look at CD #2 (if I am not wrong) and you will find the book "Controlling the Word with the HPIL". There are many good information there. I read a few parts of it briefly, because I'm still learning hwo to deal with the HP7.
One thing I did so far was to connect the HP41 to the HP71B and execute ID in the HP41 (if I am not wrong, ID is an Extended I/O function, not a standard HPIL funciton; you should check, please) and I could read:
[HP71 ]in the HP41 ALPHA register. They talked to each other!
As I'm getting acquainted to the HP71 I'm asking more questions, too.
Hope this helps for now,
