TI-92 Clone: common questions

What microcontroller does the TI-92 Clone use?

The TI-92 Clone is built around the Connector-ML_RPi_GPIO-rpiZEROConsole-rescue, from the Raspberry Pi family.

How big is the TI-92 Clone PCB?

The TI-92 Clone measures 205 × 113.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TI-92 Clone?

94 components, from 87 distinct parts. The full bill of materials is listed on this page.

Where can I download the TI-92 Clone design files?

From the ccadic/TI92-revive repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the TI-92 Clone design in my own project?

The repository has no license, so all rights stay with ccadic. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the TI-92 Clone without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
