About the Uz8021-v2 PCB
Uz8021-v2 is an open source PCB design by adzierzanowski, published on GitHub. It is a 2-layer board measuring 124 × 126.5 mm, with 50 components from 10 distinct parts.
Other key parts include the Z80CPU, CY62256-70PC, M52065 and 74HC14. By type, the board carries 23 resistors, 14 diodes, 7 ICs and 6 connectors.
It belongs with the retro computing and displays & leds designs in this gallery.
From the project
Zilog Z80 (and Intel 8080) assembler/disassembler for everyone and some other tools for my private Z80 stuff
This is a scratchpad repository containing my Z80 sandbox.
The assembler is more-than-two-pass assembler to make code more readable than optimized.
I've also written a 2-pass Z80 assember in C which is much faster. Check it out here.
For now the other part of the project consists of:
a main board with 10 MHz Zilog Z80 CPU and some LEDs, a RAM board with two 62256 SRAM chips, 32 kiB of memory each and 7-segment displays showing data and address bus state, * a CLKMOD board acting as a clock and interrupt controller.
