This is a microcode emulation, not a function emulation of the original calculators. I actually do not understand well the very complex calculator logics. I just implement the the original TMS080x 4 bit mcu and have the calculator ROM run against it. I believe the TI DataMath ROM was obtained from a TI patent document, while the Sinclair Scientific ROM was extracted by reverse engineering a 40+ year old chip via acid bath and microscope analysis.
The emulator was created to be;
Emulation core is based on Ken Shirriff's work. This is not a new project. This project was done in June 2014. I am creating this page here to link this to a tindie project page and sell the remaining kits I had created over the years.
This kit uses 2 of the now retired HP QDSP-6064 LED module. The PCB was designed to have these LED modules fiction-fit installed instead of soldering. They can be repurpose into other projects and should not be soldered.
