Update #2: of course, being the newbie I am, poor diagnosis.
All the selectors for each bit are just fine. I had just been “feathering” the keys rather than pressing down on them fully. No issues there.
Carriage return, however, is a slight issue in which the carriage returns but not fully - I need to manually move it to its furthest extent before the spacing mechanism works correctly.
I will still look to the more permanent solution for the magnet loop. I got a reply from Paul for that power supply so (in spite of what I anticipate to be elevated shipping rates) I might gear towards that.
I continually appreciate your inputs and feedback. Please do let me know if I may have missed anything based on my findings above.
Regards,
Jomar
