The Group Buy for the KeyI-84 is now open! If you have been seeing those 4 function calculators hitting the top of r/mk and wished you could have a fully featured graphing calculator with custom switches, this is what you have been waiting for! We have designed 2 PCBs that connect to the original PCB of a TI-84 Plus CE, a custom aluminum top (with angled display) and bottom plate, and a set of keycaps to be produced by Signature Plastics containing all the legends from the original calculator. This does not change the function of the calculator in any way, and is a hardware only modification, which does not have to be tethered to a computer and retains the original calculator’s battery.
This product is fully assembled and ready to use out of the box.
Does not include cost of switches. You will have to either send switches to us or order them directly to us. To facilitate this, place your order, then send an email to firstname.lastname@example.org with the subject “Order ### Switch Mail” (insert your order number for ###). If you place the order with this option, but don’t send an email, we will try to contact you, but within a week of the groupbuy ending you must get in contact with us. If not, your order will be refunded except for the 3% paypal fee.
