I have ordered a pcb for my Z80 homebrew computer project (based on CP/M 2.2 os). The new pcb is an extension of the main board, which contains a level shifter (to 3,3V) and the 256Mbit flash chip. The flash chip represents four 8MB disk drives in CP/M. The pcb has been designed with Eagle layout editor (old version 6.5.0). The PCB ordering process in elecrow is versy simple: 1) Add a zip the all layout files created by the Eagle job. A preview is shown! 2) The size of the resulting pcb is automatically calculated by the web page. Select the color of the pcb. 3) Order the pcb. 4) Get the pcb about two weeks later.
