MC-10 Tape Emulator: common questions

What microcontroller does the MC-10 Tape Emulator use?

The MC-10 Tape Emulator is built around the CH32V203C8T6, from the RISC-V family.

How big is the MC-10 Tape Emulator PCB?

The MC-10 Tape Emulator measures 102.1 × 73.8 mm, has 4 copper layers and is 4.69 mm thick.

How many components are on the MC-10 Tape Emulator?

95 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the MC-10 Tape Emulator design files?

From the SteveLRojas/MC-10_Tape_Emulator repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MC-10 Tape Emulator design in my own project?

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

Can I test firmware for the MC-10 Tape Emulator without the hardware?

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