I'm waiting for the prototypes of the 2x4KB cartridge clones to be delivered, so i started a new project:

A clone of the DragonPlus Expansion Board.

Top layer is finished.

First look:

Hi,
great work indeed!
This is a very interesting project.
Are you planning to order a small batch when finished?


cheers

Hi,great work indeed!

Thank you Some mistakes are going to be fixed though

Are you planning to order a small batch when finished?

If enough people are interested, i will make a little batch.
If not, i make it myself, because then it's cheaper.

Hi Fabian,
I will gladly buy two boards.
One to 'collect' this artwork and the other to be populated and used on a Dragon64

cheers

The second layer is finished.
Now i have to get a new pair of eyes
But i find it looks stunning..

Here for your viewing pleasure.

It looks awesome!

I've uploaded a picture of the character set and linked the dumps of the character rom and the prom to the Dragon Plus page.

Cheers,
Rob

Has anyone managed to get a good dump of the 82s147 PROM ?

I have a plus board where this has failed, would be good to replace it sometime.

Cheers.

Phill.

Phill, just take a look at the Dragon Plus page, I just uploaded a good dump of the 82S147 PROM.

Fabian, welcome to the forums! What a beautiful project!

Do you have the original board, or are you basing it on the photos in the wiki? What do you use for layouting?

Robcfg, by the way, what is the story of the clone boards on the wiki page?

Manu sent me the boards that are scanned in the wiki.

He had the original board with everything removed, and the clone board with the original components fitted.

I dumped the character rom and prom chips, and I'm trying to make the board work. Anyway, we have what we need to emulate or clone it.

I think he got the board from a computer shop in Paris, that was about the only distributor of Dragon stuff near to where he lives. I'll ask him if he remembers anything else about it.
