The Sega Genesis Nomad. What an amazing beast. Didn’t work up until today. The seller had kindly offered a full refund if I returned it. Not while I have an empty weekend to do some repairing! I knew there was a definite issue with the DC-in jack as it was as loose as a goose.
So I pulled the Nomad apart and found that the DC-in jack was damaged causing positive and ground to short! This is likely why it was not working with a battery pack installed. I followed where the DC-in jack traced back to and soldered one of my DC-DC step down converters (after calibrating to 9V) from the Saturn external PSU project. Soldered on the positive (red) and ground (black) and bingo! Life!
After closer inspection I found (unsurprisingly) that the DC-in jack was exactly the same as a Mega Drive 2. Centre positive as well. I removed the DC-in jack off one of my functional Mega Drive 2 units and attached it onto the Nomad.
Replaced the front plastic screen and cleaned out the controller buttons, put it all back together and plonked in my nearest cartridge(s). Tested with the external battery pack and it works well also. A great success! Here’s a video of the Nomad during initial tests too.
All those and more, we also have a new editor who will be focusing their work on Famicom – Please welcome Nick to the scene. He already has a Famicom on the way and is relatively new to the world of soldering and tinkering. He was voted most silent person in the Counter LED videos here and here
Some great news and some even better news followed by unreal news though. As you can see above there are three items. A TeraDrive, Mega Drive and a Nomad.
The Nomad is broken – no power off AC and no power off a battery pack. I have no GameBit to disassemble it at the moment. It’s good news though because I get to attempt to repair it. Will victory be mine? Stay tuned!
Next up we have the Mega Drive 2. I purchased a broken Mega Drive 1 to use with the Mega CD / TeraDrive expansion slot and to scrounge together some parts to fix up my more prized High Definition Mega Drive 1… However the seller I bought from had other intentions – sending me a Model 2 Mega Drive. I contacted them and they are sending the other Mega Drive 1 up to me and told me to keep / throw out the Mega Drive 2. Small victories!
And lastly but certainly not least – The TeraDrive has been tested and works well. Both floppy drives are functional. I have been unable to test the Mega Drive side of things – but it should be working. I’ll know once I pick up one of those 15KHz video converters that has been on my to buy list for quite a while now. I have also uploaded some of the flyers and the quick reference guide that came with the TeraDrive – it’s over in the galleries here
Of course I could not sign off without leaving a video…
Just a quick update – I received the Sega Mega CD Karaoke add-on today. Gave it a test and found there is a buzzing noise from the unit when it is powered up.
More annoyingly the microphone does not work. I’ve pulled it apart – Pictures Here – and found the microphone cartridge seems to be dead. So I’ve gone ahead and bought a $10 600-ohm Model BG-58 microphone replacement cartridge off eBay. It will be a few weeks before that arrives though.
In the mean time I have purchased a very nice looking boxed Yukawa Dreamcast – My first international Dreamcast. I am still waiting on the Nomad to arrive from the US – the good news is it has hit land here, shouldn’t be more than a few days now before I am gaming on the go!
All you avid retrojunkies might have noticed that the menu bar has slipped up to the very top of the page. I am still tweaking the banner and alignment, but it is good enough for now. Here’s to the week ahead!
