Designing Vectrex clone - circuit diagram final

dub 18, 21:02

9.3.2011

One week later …

Every second wednesday is 8bit club, layout of board is more or less finished.
Only some part for generating CE, OE and RW for RAM is discussed (Thanks Poke) and than we have PCB layout. It is very similar to original board.

Main changes:

  1. most of parts are SMD
  2. layout support 68A09 and 68A09E
  3. ACB stereo for output from AY-3-8912
  4. -5V regulator on board

Attached are some pictures, design files come later.

Designing Vectrex clone - circuit diagram

dub 18, 20:41

When I take something into head, I want to finish it as soon as possible.
For some peoples it looks that I have nothing elso to do, but I have only very strange job (service technician) :-)

Because this I have to spend a lot of time on bussines trips and what else should I do when I am at hotel than cloning Vectrex?

Than one week later we have circuit diagram, with raw pcb circuit layout.

Attached to this post is circuit diagram in Kicad format

Designing Vectrex clone - first idea

dub 18, 20:03

23.2.2011

Vectrex was one of “toys” which I want to have. I checked ebay lot of times, but because CRT it is not so easy send this to Czech republic.
Than I postpone this and leave it for future.
This was few years ago.

Two months ago things start to move.

After discussion at 8bit computer club in Brno with Poke I decide to create clone.

First idea was:

  1. copy complete main board with only small changes
  2. as vector display use XY scanned laser

Blog?

dub 18, 19:51

This blog is something like log of my last few weeks which I spent working on Vectrex clone. This was not written during my work, but afterwards.

I hope that this should be good inspiration and may be some more clones will appear…
