Hello all,

firstly, apologies if this has been asked (I couldn't find it though).

Secondly:

Has anyone created a Schematic of the Original Megadrive #1 (the one with the External Port on the Back) that could be read using some form of modern Schematic Viewer/Creation Application? If it runs under an Open-Source Application then all the better.

I know that we have that terribly poor quality Schematic from Years ago but it's a hassle to use, I find.

Many Thanks,

Minty.

If this and this is poor quality for you then I have nothing to say.

I find those 2 files very usable too, all letters can be read and all lines traced easily...

Indeed they can be read. However they cannot be searched and do not benefit from being in a Format useful to a modern piece of Schematic Software.

I suppose this comes down to People favouring a manual Approach or a Software assisted Approach - one takes Time and relies on the Person having the Time and being awake, the other automates much of this and would indeed save Time.

You Guys carry on reading manually.

One can always invest the time to make a "prorper" schematic, but I guess the mindset is that it takes a lot longer to referenge the images for 15 seconds and find what you want, and later 1 second references with software arent wort the time to get that far.
At least that is how I feel.

Indeed. Print this pics to A4 paper and all looks just fine. And yes, F3 (Ctrl+F) doesn't work with it, that's pity. Poor new generation.

Yes, this is quite clear.

I asked prior to investing any Time on this myself.

It would be a useful Resource for the Megadrive Community though - I shall set about giving our Community what will benefit it.

I think that you are attempting a Quip there - more fool you.

The Aim should always be to improve our standing and thus make it possible for us all to move forward development wise - you can continue to do it the hard way for me, Hardwareman.

If I made anything it would be made in Basic Schematic

It has been a few Years since I had to create a Schematic, as such, what's the most universal Format/best Format to create it in? I used to use EasyPCB and Eagle.

Ideally I'd like to go for something that would allow Open-Source Applications to read and modify the Schematic for future posterity.

I use BSch out of preference. I can work with it about as comfortably as with pen and paper (I still prefer paper).
It is open source, so if one really wants, one can add support for other formats.
I could not got into other free programs, the programs I liked where veeeeery expensive commercial things and I'd stay away from pirating.

Why make it complicated is that it's easy? What do not you like about these schemes except the quality? The fact that the symbols are not on the IEEE/ISO standard?

None of your further Comments are useful to this Discussion, thank you.

Very good. I shall look into what the Options are. I shall get my Megadrive #1 PCB and attempt to get an accurate Trace as compared to the Photocopy that we have made use of up to now. I'll work on my PCB with the extra External-Port on the Back (one of the earlier European Models).

Having the Schematic in a digital format will permit others to perhaps use it with their own Designs in future.

Thanks for your Input.

OK, I get it. Want someone to do everything for you. I'm leaving.
