Very nice, interesting and helpful! I like especially the Rowtron and the OC-2000 carts, those have interesting shapes <img decoding="async" class="wp-smiley" src="/wp-includes/images/smilies/icon_biggrin.gif" alt="" />

Atari 5200 carts are big too: 11.3 x 10.4 x 2 cm. But I think it's possible that the Rowtron carts are even bigger.

Yes, Xonox carts are longer, but not as wide and high.

Notes:

Acetronic & Radofin carts are beside the color identical to cartridge pong carts by Acetronic, Audio Sonic, Blackpoint, etc.

ITMC carts are identical with the Arcadia carts by Ormatu, Sheen and Intervision and the cartridge pong carts by Unimex (Mark IX), Poppy (9015), Conic (4a8), etc.

Being identical means that they also have the same size and shape?

Very interesting! I wonder how many people inserted cartridges in a wrong system and wondered why the game would not run

Or do the connectors on the PCBs have different sizes so that it's impossible to insert the cartridge the whole way into the wrong console?

But the games would not run on the “wrong” console, no?

Someone should check all possible combinations, maybe we find something out here, maybe ITMC and Unimex Mk IX carts run on the Ormatu/Sheen/Intervision consoles, three generations on one machine, LOL

But seriously, at least the Interton and Arcadia compatible systems share almost the same hardware, don't they? Doesn't the Arcadia family have just an upgraded version of the Interton CPU?

Edit: Ok, found it. The two systems share even the same CPU, the Signetics 2650A, and almost the same video chipsete: Signetics 2636 for the Interton family, Signetics 2637 for the Arcadia family. Does anyone have data sheets of those two video chips? If the share the same instruction set, it should not be very hard to make Interton family carts playable on Arcadia family consoles ...
