Thanks!

Just need to work the controller port out (5 min job) and post pics, and then make and upload the SMS video.

Will then start the next system - NES. More to do on that system probably, ie maybe region free.

Each system will be left barebone, as the idea is to finish all consoles and then make a case and cram them all into it.

After NES, probably do Intellivision; etc.

Second system: Nintendo Entertainment System - NES

Did all the below with no research, just worked the stuff out myself (more fun if you can do that).

Opened NES console, removed the board. The large silver box on the top left is the RF / AC power (yes, AC) / composite out / audio out.

Image

As per the SNES, the AC in only gets converted into DC that then gets converted into 5v by the 7805.

Couldn't desolder the large bits that connect the silver box to the motherboard, however, these contacts are always ground, so used a small drill and carved the bits off the board! Brutal, but works. This only left five contacts that were easy to desolder.

Image

The game cart port worked occasionally, so needed to bend the pins back a little so the game cart slotted in better, used a needle for this. The small board is the game cart board, which only takes about 25% of the space inside the cart. Nintendo made it this large so it could be loaded like a VHS tape in the day.

Image

Spent about an hour and a bit getting the shilding off the small board in the silver box, removed the RF modulator box too, just have a couple of capacitors to relocate, and remove that large capacitor and replace with a smaller one.

Image

Used a little sticky tape to get the game cart roughly level; powered system - all fine so far.

Image

Some of the board can be trimmed but nothing major, probably 10-15%, the expansion port can go, capacitors relocated, mod the cart port to then be extended with wires.

I'm just wondering how on earth you're going to be able to put it in a case with 11 cartridge slots and make it look at all presentable.

I looked at the empty NES console casing earlier and thought to myself that if I were only incorporating about 4 or 5 consoles into a system, i'd probably have used that. That's why i'm thinking of frankencasing an Intellivision console as it is wider - might get two consoles side by side in layers, maybe - time will tell if it fits. It not, i'll look at "fake console designs" on YouTube for nice case ideas, and make one of the designs for real - futuristic design.

He could use a sliding lid, like the Master System 2 has, to hide the cart slots.
