The picture on ebay was of low quality, however and I could not see the display very well. It looks like the display area was pretty small though so I'm guessing it may be an LED type display.

Ah! This makes much more sense. I'm pretty sure that the 1330 does have an LED display and the same (or similar) Seiko printer as used on the 46.

I'm not sure why the printer drum does not turn when you turn the printer on, it might just be stuck. Try pulling the paper though when the printer show be running this might start up the drum. I have this problem with a Wang 500 calculator.

Even if you get the drum to start turning you still might have a printer problem. The HP-46/81 often needs to have the power supply capacitors changed before it will work properly. Read this artcile about it.


The HP-46 is a far more interesting calculator than the Monroe 1330 and much, much more collectable. So don't feel bad about paying a lot more for it, it's something a lot of collectors here would love to have and will pay a good price for.
