Multi Calculator Kit

[PANAMATIK]

The year 2017 is the year of the multi calculator kits. Three different multi calculator boards are in development. Teenix probably the most complete on a dedicated board, Harald a replacement board for the Classic series based on teenix software, and my "Low Power" board for the Woodstock hardware.

Here a brief comparison as far as I know

Teenix:
All Classic 35/45/55/65/70/80, all Woodstock 21/22/25/27/29 all Spice 31/32/33/34/37/38 and 67 and 19C running on a new developed board with own keyboard.
Some of the models are simulations rather than true emulations. (Correction added: ALL models are true emulations)
Using 16-bit PIC PIC18F47K40 with 128k Flash memory
Easy to assemble or ready to use PCB.

Harald:
All classic 35/45/55/65/70/80 (Correction added: also all Woodstock and Spice models like teenix's) running on a board which fits into the Classic hardware, using the original case and keyboard. Easy to fit into the calculator just by plugging in.
Based on teenix software with dedicated Classic display driver interface
using 8-bit PIC processor (Correction added: using Renesas processor with DMA Cntroller)

Panamatik:
Classic 35/45/55/70/80, all Woodstock 21/22/25/27/29 all Spice 31/32/33/34/37/38 and 67 running on any Woodstock hardware using he original case and keyboard.
Based on new ACT software with many extensions. True emulations of all calculators.
Using 8-bit PIC16LF1819 with 32k Flash and 512k external Flash, IR printing, GPS receiver, Real Time Clock. Relatively difficult to plug in, because two ICs have to be unsoldered and modifications of the board have to be done.

The race is on. Who will have finished his software first. I'm still struggling
