HP-71B and some (to me) interesting modules

RE: HP-71B and some (to me) interesting modules
Thanks Jan, for sharing all these details. And great news that you will order a PIL-Box, it will unlock and ease exploration of your 71B and all the wonderful software around the community for it.

I'm a bit confused about your configuration though. In the SHOW PORT output, it shows a 16KB ROM (or EPROM) which you list as being a 64K RAM module, and also 32K RAM in ports 4.00 and 4.01, which would have to be the 64KB RAM module. I assume these two modules were swapped between you initial SHOW PORT and later description, is that the case?

The EPROM in Port-2 looks uninteresting (all files are BASIC) however the names have no meaning for me as I don't read German. Can someone suggest Anglicized versions of the filenames?

OTOH, the module in Port-3 looks quite interesting with several new looking LEX files.

I suspect the modules are used as a pair, with the P2 module containing all the application specific code, and P3 containing utility keywords and BASIC (sub?) programs (INDEX2, PRINT), and it will be interesting to explore these once available.

While waiting for your PIL-Box, suggest you read up on the ROMCOPY LEX file, and also start to explore Joe Horn's Online LIF Disk Project, a collection of most of the community LEX and utility files for the 71B, 75C and a little 41C stuff.
