acromite53 | 337 Posted October 22, 2019 Share Posted October 22, 2019 (edited) I'll be documenting my progress here in the making of a Sega Neptune. Here is the bottom of the system. I have relocated the capacitors so they won't be in the way of the 32x board. The Genesis board still fits in the bottom shell. The capacitors don't get in the way. You can see that there is a lot more space to work with now. The cart slot has been cleanly removed. I'm testing the length of wire for the cartridge slot extender. I am using a Cat 5e ethernet cord to source the wires. Here is what the reverse looks like. I will be relocating those 3 black components to the bottom as well. I've begun adding wires to the cartridge slot. I tinned the pins and stripped cables. I will be bending the wires underneath the cart slot.

SoleGoose | 95 Posted October 22, 2019 Share Posted October 22, 2019 I bought a specific 3D printer just for this type of project. Haven't got around to it (and might never), but I'm curious to hear about your attempts as you go. Link to comment Share on other sites More sharing options...

A neptune casing would be awesome. Link to comment Share on other sites More sharing options...

acromite53 | 337 Posted November 1, 2019 Author Share Posted November 1, 2019 One side done. 32 more to go. Link to comment Share on other sites More sharing options...
acromite53 | 337 Posted November 11, 2019 Author Share Posted November 11, 2019 Ok this is so frustrating. I have the whole cart slot soldered in but it will not read carts. I get the boot up message and then a black screen. Sonic 1 doesn't even give the startup message. I have no clue what the problem is. Is the signal not transmitting through the wires? I'm using stranded 24 AWG wire. Should I use thicker or solid? I just dont know. Link to comment Share on other sites More sharing options...
MachineCode | 159 Posted November 13, 2019 Share Posted November 13, 2019 Solid vs stranded wouldn’t matter there. Check continuity between the pins inside the slot where the cart actually contacts them, and the solder points on the board. If that’s good, check to make sure that you haven’t accidentally bridged any connections when soldering using a continuity tester as well Link to comment Share on other sites More sharing options...
