3D Printed Cartridge Case (Part 1)

Thought you fellows might quite like to see this: my order just arrived moments ago and contains a 3D printed lid for a Dragon 32 cartridge case. http://i188.photobucket.com/albums/z47/Rinkwraith/34FC9AC5-35AA-4D32-906A-05DD7FAB8D4D-3652-000000E2FE41DF48_zpsc3895074.jpg http://i188.photobucket.com/a...

Any use to you? Not that it matters, it's as good as it's going to get. ;)

Re: My Dragon cartridge boards (actually work!!!)

Please place the PCB in the center of an A4 sheet of white paper, and take a photo with the camera directly facing the solder side. This quick, simple task is all I'm asking for. :) Lol. Will do mate. It's pretty gloomy here today so will have to source a few extra lights and things - or a better c...

Re: My Dragon cartridge boards (actually work!!!)

Would it be easier if I just post the PCB images from the design software? Waiting on a new power supply for my laptop but I suspect it'd be a lot clearer than trying to make out black tracks between a black ground fill under a black solder mask. :)

Finishing work earlier today so it should be light when I get home - will try this afternoon. Promise. :)

That's just a dual NAND gate IC for inverting R/W. Only using one gate of it but I have so many of the things that I just threw it on for convenience.

Re: My Dragon cartridge boards (actually work!!!)

Drat - can't get an anywhere near usable photo tonight, there's just not enough light.

I should stump up for some decent light bulbs.

Re: My Dragon cartridge boards (actually work!!!)

The PCB price is a little high, but not too bad. I would be willing to pay about $15 - 20 each (including postage) for a slightly modified version of this PCB with just a 28 pin IC socket fitted (for inserting a 27128/27C128 - 16K EPROM). Never played with a 27 - have you ever tried reading from a ...
