Vectron VGA Plus

Topics regarding the Uzebox hardware/AVCore/BaseBoard (i.e: PCB, resistors, connectors, part list, schematics, hardware issues, etc.) should go here.

Vectron VGA Plus

Post by danboid »

I have seen a few people ask about adding VGA output to the UB so I wonder if it might be possible to use the Vectron VGA Plus for that purpose, if its possible to wire it up and write a driver for it? Its description reads "Vectron VGA Plus v2 generates a 640x480@60Hz VGA signal and has an interface that works with retro computers or microcontrollers." which sounds promising to me.

I thought it might be worth posting on here to get the thoughts of the more experienced hardware hackers, which doesn't include me.

This board was created as an addon to the Vectron 65 plus which looks like quite a cool open source 8 bit computer:

The Uzebox does not really have an external address bus - so it would be quite a kludge to attach this.

It also isn't really in the spirit of the Uzebox "2 chip design".

I think if you wanted VGA out from the Uzebox you would just replace the AD723 with some chip that would be a scan doubler. A smallish FPGA could do this.
