dphirschler Posted November 5, 2014 Share Posted November 5, 2014 I want to replace my old battery in the Mini Memory cart with a socketed battery. Before I open my cart and measure it, can one if you tell me the dimensions of the battery socket I need? Hoping it's 20mm as I have a new battery here ready to go.

+arcadeshopper Posted November 5, 2014 Share Posted November 5, 2014 (edited) So much easier to change now: (btw this one works on the mobo too..) 2032 cell Also there's these instructions http://www.mainbyte.com/ti99/minimem/minimem.html Edited November 5, 2014 by arcadeshopper 5 Quote Link to comment Share on other sites More sharing options...
+OLD CS1 Posted November 5, 2014 Share Posted November 5, 2014 Good question. I am really not sure. I got a handful from Mouser to do mine. You can see it in my gallery. Quote Link to comment Share on other sites More sharing options...
dphirschler Posted November 5, 2014 Author Share Posted November 5, 2014 I don't want the battery external. And the mainbyte site only tells you how to solder a new one in, not a socket. Doesn't even tell you the size of the battery. This is below mainbyte's usual standard of thoroughness. Darryl Quote Link to comment Share on other sites More sharing options...
+save2600 Posted November 5, 2014 Share Posted November 5, 2014 It's a standard CR2032 type coin cell battery... and a socketed one probably doesn't fit inside the case, hence the soldered solution. Looks like they're not taking orders anymore either, but I'm sure you can get those batteries with the soldered leads at a place like Mouser or Digikey.

+OLD CS1 Posted November 6, 2014 Share Posted November 6, 2014 I used these from Mouser: 571-1205911 The Mini Memory board is a lot more "friendly" than the Amiga 2000 or Amiga 4000 for 2032 sockets. 2 Quote Link to comment Share on other sites More sharing options...
Fritz442 Posted November 6, 2014 Share Posted November 6, 2014 (edited) I used Radio Shack #270-009 holder, but you have to remove the protrusions on the bottom to make them lay flat against the board. I removed them with a dremel tool and flattened the top arm just a bit and push it down all the way. Cut the new inner slot on board. Last image with door removed.

dphirschler Posted November 6, 2014 Author Share Posted November 6, 2014 Just found a coin battery socket I can scavenge from an old PC motherboard. I don't know why it just now occurred to me to look for it there. I've been scavenging parts from this board for about a year. I'll let you all know how the surgery goes...

dphirschler Posted November 7, 2014 Author Share Posted November 7, 2014 Well, the coin battery socket (from a CMOS battery in a PC) is too small. It's 20mm. The one in the Mini Memory cart is easily 24mm or more. So I don't think this is an equivalent replacement. Darryl Quote Link to comment Share on other sites More sharing options...

It does not have to be a 24xx or 23xx, a 2032 works just fine and is abundantly available. 1 Quote Link to comment Share on other sites More sharing options...
dphirschler Posted November 7, 2014 Author Share Posted November 7, 2014 Oh, that's good to know. Darryl Quote Link to comment Share on other sites More sharing options...
dphirschler Posted November 8, 2014 Author Share Posted November 8, 2014 The problem is (and I should have probably noticed before I soldered it in) that there isn't enough vertical clearance for the socket. grr! OLD_CS1, does yours fit in the closed shell? I'd just like to know for sure before I order one from Mouser. Darryl Quote Link to comment Share on other sites More sharing options...

OLD_CS1, does yours fit in the closed shell? I'd just like to know for sure before I order one from Mouser. It sure does! I searched for the lowest-profile socket I could find. Tell you what: I am pretty certain I have a spare or two. I will dig through my bins tomorrow and if I have one I will ship to you Monday. Can you wait that long?

+OLD CS1 Posted November 10, 2014 Share Posted November 10, 2014 I cannot find my spares in my parts bins, but they might be in storage. I was planning on heading out to storage tonight. Quote Link to comment Share on other sites More sharing options...

+OLD CS1 Posted November 16, 2014 Share Posted November 16, 2014 My two spares went out USPS Priority (apparently you cannot purchase a lesser service on-line directly) yesterday. We are all waiting to see the outcomes, fellas! Quote Link to comment Share on other sites More sharing options...
dphirschler Posted November 26, 2014 Author Share Posted November 26, 2014 I've completed the surgery, but I haven't tested it yet. But it did fit back together this time. :-) Darryl 1 Quote Link to comment Share on other sites More sharing options...
