repairing/testing 82161a IL issue using 82162a

[dmh]

Thank you for the detailed and informative replies so far.

I have 2 x 82160a IL modules and calculators, however, I do not have an IL Development module and when I've seen them available they are VERY expensive!

I am planning to purchase a PIL Box but they are still unavailable. Not sure I can justify buying 2 though.

I will connect the printer and the tape drive in the same loop and see if I can print and advise.

I haven't opened anything yet, is the IL chip socketed or soldered?

Thanks, dmh
