Please note that due to my travels around the annual HP Handheld Calculator conference, no orders will ship until after my return on October 7. Thanks for your patience.

WP 34S Overlay

I am accepting orders for adhesive vinyl overlays for the WP 34S layout to apply to an HP 20b or HP 30b. The price is $6 for one or $5 each for two or more, including shipping anywhere in the world.

At present it is printed on waterproof matte white self-adhesive vinyl, with a protective spray with a satin finish. The adhesive is very strong, so be extremely careful when affixing it to make sure you have the alignment right. I highly recommend you use a needle-nose tweezers for applying the key labels to ensure precise alignment.

If you would like the alternate white shift keys and the / division symbol instead of what is pictured below, please make a note when sending payment and I will give you that.

Due to printer issues, I am having problems making these again as of June 2018. Please expect a delay of 2-3 weeks prior to shipment.

Please select the desired quantity and then click "Pay with PayPal" to pay for it. Please allow 2-3 days before it will be shipped.


I have more information about the WP34S, including the ability purchase a full-configured calculator, here. If you would like to make your own, I have written directions on how to flash the calculator.

This is what the overlay looks like when placed on a calculator:
