ti59 and TMC0501 microcode simulator

This project allow to run microcode for TMC0501 generation calculator. See http://www.datamath.org/Chips/TMS0500-CS.htm for more information

This is based of previous work from Hynek Sladký :

The goal is to able to run microcode of several calculator and understand how the differents chips work together.

For that each chip is implemented in a separate file and communicate with bus like shared data.

How to use it

build (only tested on linux)

make

download firmware

./bin/get_rom.sh

run the selected model

./bin/SR50.sh

./bin/ti59.sh

Key mapping is print on startup

You can check doc dir for more technical information.

printer

you can pass option "-p" to enable printer

./bin/ti59.sh -p

CROM

you can pass option "-l" to load master lib

./bin/ti59.sh -p -l rom/module-lib/TMC0541.txt

You can test it using "2nd Pgm 01" "SBR ="

It should print

MASTER
1

and display "1"

Additionnal library module can be found on http://www.datamath.org/Chips/TMC0540.htm

Debug

log

You can enable log in log.txt file

  • '-v level'
    • level=1 : low
    • level=3 : medium
    • level=7 : high

ROM

You can disassemble on stderr the rom with '-d' option

./bin/ti59.sh -d

./bin/SR52.sh -d

CROM

You can disassemble on stderr the rom with '-D' option

./bin/ti59.sh -l rom/module-lib/TMC0541.txt -D
