About the Mem PCB

Mem is an open source PCB design by ddanila, published on GitHub. It is a 2-layer board measuring 100 × 60 mm, with 6 components from 4 distinct parts.

Other key parts include the DIP-28_W15.24mm, DIP-32_W15.24mm and DIP-24_W7.62mm. By type, the board carries 3 ICs and 3 capacitors.

From the project

Reconstruction of the Soviet/Estonian Juku E5104 processor board as both a physical PCB and a runnable, headless digital model. The project’s distinctive piece is an LVS-style check that compares the structural Verilog connectivity with the machine-readable board model.

- The C emulator and the structural jukutop model boot the real Juku ROM, render the same framebuffer, accept keyboard input, boot EKDOS from the vendored disk images, and reach disk BASIC READY. The deep value-level guard sync/cosimcheck.sh compares jukutop's typed CPU-bus events against the C emulator (cosim). The default…

Mem: common questions

How big is the Mem PCB?

The Mem measures 100 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mem?

6 components, from 4 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Mem design files?

From the ddanila/8080-cosim repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Mem design in my own project?

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