I'm playing with coding vector graphics on an arduino with an oscilioscope display.
I was thinking of transplanting the arduino into my vectrex to give it a big processor boost.
I am guessing that as some point there is an x,y input to the tube amplifiers that i could patch into (without destroying the unit).
Has anyone done this before?
Looking at the schematic, there's a single DAC for x axis. This is also fed to an analog mux to give the y and z outputs.
There's a very convenient connector J301 that takes the l.v. signals x,y,z to the crt power amp board. So That's where to hack in....

In the manual it shows step by step how to connect to a Vectrex monitor. www.zektor.com/zvg/downloads/vectrex.pdf |

It's a converter that goes between the vectrex and a pc and it costs $250! I will progress my arduino version... The vectrex uses +/- 5v so an intermediate amp is required. |
