The Scopetrex is a project by Tube Time for recreating the original Vectrex circuit on a modern PCB using components that are more easily available today. It is designed for displaying on a cathode-ray oscilloscope with an X-Y mode, or other vector display. Construction details, PCB layout, and schematics are at GitHub.
These PCBs have been manufactured based on the Rev. 1.1 design files from the GitHub page - the controller boards are not included. The parts list includes part numbers for ordering almost all the parts from Mouser, except for the sound chip, the CPU, and the right-angle cartridge socket. For your convenience, these rarer parts are available to buy here with the PCB. The included models are a YM2149F for the sound chip (substituted for the original AY3-8912, as allowed for in the Scopetrex design), and an EF68A09EP CPU (select the "E-suffix" parts list to suit this chip).
The EEPROM used in the Scopetrex design may by out of stock. It also needs programming with a compatible programmer. Although this model of chip isn't available, our OmberROM programming service can supply a AT27C256R-70PU non-erasable EPROM which will also work. However in that case a modification to the PCB needs to be performed during construction, which is also described in the notes.
