About the Zilog MultiSerial PCB

Zilog MultiSerial is an open source PCB design by roberto314, published on GitHub. It is a 2-layer board measuring 100 × 100 mm, with 42 components from 26 distinct parts.

Other key parts include the Z8440, 74HC14, IS63WV1288DBLL-10xLI, 74LVC253 and 74LVC595. By type, the board carries 21 connectors, 10 ICs, 5 capacitors, 4 resistors and 2 jumpers.

It belongs with the retro computing designs in this gallery.

From the project

A modular 8-bit Computer able to recreate (nearly) every Retro computer of the late 70s to mid 80s.

A modular 8-bit Computer able to recreate (nearly) every microcomputer of the mid 70s to early 80s in Hardware without FPGAs (although an FPGA can be added). Can also be used as a teaching tool for:

VHDL or Verilog C RTOS (STM32F401 runs ChibiOS Link: https://www.chibios.org) Python bash and linux in general (Olimex board runs linux with fbterm and tmux) Harwaredesign Timing of CPUs maybe Assembler SPI and I2C Interfaces CPLDs and FPGAs
