About the CY7C1041DV33 SRAM Board

CY7C1041DV33 SRAM Board is an open source PCB design by snorklerjoe, published on GitHub under the MIT license. It is a 4-layer board measuring 69.9 × 95.3 mm, with 102 components from 18 distinct parts.

Other key parts include the TXS0108EPW, 74FCT521ATSOG8, 74ACT139 and 74LVC244APW. By type, the board carries 50 resistors, 29 capacitors, 11 ICs, 8 diodes, 3 connectors and 1 jumper.

It belongs with the retro computing designs in this gallery.

From the project

A homebrew 65c02s-based computer and custom operating system, with a handful of modern features.

The goal of this project is to build a 6502-based portable machine, running my own operating system.

See the complete implementation plan and progress here: Implemementation Plan

PCB assembled, PIC is able to load code for the 6502 to execute, the 6502 can read/write to the 2-port SRAM.

These are some general points; for the full hardware specification, see here: Hardware Specification
