I recently acquired this device with no doc's so I'm not sure how to test it to see if it is working. When I plug this empty (no eproms) unit into my HP-41CX, should I be able to read anything from my calculator?
Anyone know how to configure the dip switchs for some valid combinations of eproms?
Some photos and a blog post

I know only one switch setting for a 16K EPROM-Set with 2x2764 and 1x 2732.
The left 4 switches on the picture in your blog are selecting the type of EPROM-Set. 1 up, 2up, 3 down and 4 down is 16K. Only switch 2 has to be different to the picture.
With the other bank of switches on the right side you can select between port 1+2 or 3+4 in this case.
Thanks Winfried.
This helps alot. I continue to build out the blog post.
I hope to clarify DIP settings for port switches so I can addrees port 1+2 or port 3+4? Maybe on inspection this will be more obvious but if you get a chance, let me know.
All the best,
Ron
