Other key parts include the LM1117-ADJ. By type, the board carries 52 resistors, 8 connectors, 8 capacitors, 6 diodes, 2 test points and 1 IC.
It belongs with the test & measurement and usb & debug tools designs in this gallery.
From the project
This is my attempt to create a 80's style computer based on the Zilog Z180 CPU
A few softwares are needed for reading/using the files in this folder :
Kicad for reading the schematics and board layouts https://kicad-pcb.org/ Quartus 2 web edition for programming the Altera CPLDs https://fpgasoftware.intel.com/13.1/?edition=web * WinCUPL for programming the GAL of the VDU board https://www.microchip.com/design-centers/fpgas-and-plds/splds-cplds/pld-design-resources
