We now have again two HP41CV units left, with all back ports and battery side cover. It is still a wonderful machine, that can be enhanced with peripheral and modules to a still competitive machine - not in speed but in functionality. And with the legendary HP keyboard click!
One unit is a full nut and the other is a half-nut: the newer design which is more reliable since it has fewer inner parts.
Price is 130 € plus shipment.
