Need some memory refresh on HP-71b and PILBox

[smp]

Hi folks,

I've had my HP-71b and PILBox stored away for a few years, and recently decided to buy the calculator stand available on eBay, so I dug it all out and got it all running again, anticipating the arrival of the stand today.

I have updated anaconda3 and pyILPER, and I've successfully attached my .dat files for Drive1 and Drive2. I copied over PILTERM.BAS and KEYBOARD.LEX and I have everything running on my MacBook Pro.

I used :MASSMEM to access Drive1 on pyILPER, but for the life of me, I am not remembering how to access DRIVE2. I tried :MASSMEM:2, but I get a "No Loop" error from the HP-IB. Remembering from my HP-86, I've been trying :D7xx and :D8xx, but those are not working, either.

I am currently digging up my PDF manuals, but have not come across the HP-IL Interface User's Manual, yet.

In the meantime, can anyone provide me a bit of memory refresh on how to access both DRIVE1 and DRIVE2 in pyILPER?

thanks very much, in advance!
