Man, your job is amazing I love your page, but…

The sync (composite) and audio cables are swap in my sg1000. I take about two days of work check every ic, caps and regulator to finally get it :D.

Anyway, keep going!. There are a lot more people who are grateful than the people who comment

Thank you!!!!

Hi, I am currently working on a casemod project. I would like to use cases of defunct old retro consoles and put a mainboard in it (frankly I doubt much fill fit in but a small mainboard and a hdd).

I’d love to do this for the Mark II and the Mark III (because I love the design). I already found the dimensions (W x H x D) for the Mark III but I can not find them for the Mark II. Can you help me out and send them to me? Because if it is to small I can totally forget about it (Mark III has enough space).

This would be great!

Thanks much!

Hi, thank you for your information. They were very valuable. I would like to tell that in my case the location of audio and composite were swapped.

I also wanted to ask you a thing. For me the colors are much more “saturated” colors than I’d expect.
With reference t the tms9918a palette , both dark red and light red are very close to what we’d say FF0000, and dark blue looks like 0000FF. For instance, the sky in congo bongo is really blue (and not violetish, as it should be) and the three reds of the first level look pretty similar. In Magical Tree, the face is red instead of pink (light red). Did you experience this problems?
