HP-41CV Card Reader "Memory Lost"

[fpatton]

I checked port 4 on both the CV and the CX with a working "Securities" card, and they both seemed to read it just fine. I hadn't thought about the port being bad, since I had tried it on both calculators, but it was worth a shot. CV edge connectors got a very good cleaning with DeOxit during the rebuild.

Oh well, it happens! We'll consider this a source of spare parts if I ever pick up a card reader. Thanks for the input!
