Goddy Posted December 3, 2014 Share Posted December 3, 2014 Hi all its a very nice forum you have here I was wonder if I can get some help I bought a few days ago a cheap Atari 600XL it works brilliant it also came with a SIO2SD I have done some googling and read a few forums and I think I am very limited to what I can run with only 16k correct ?.I have tried to run some software on the SIO2SD I have got the SD card setup ok I tried to load Dropzone and a few others but no go I guess it needs more than 16k so can anyone recommend a game that will run on 16k using the SIO2SD or am I limited to the cart games till I get my 600XL upgraded with more memory.ThanksGoddy Quote Link to comment Share on other sites More sharing options...
adam242 Posted December 3, 2014 Share Posted December 3, 2014 I don't know of any disk-based games that will run with only 16K... the good news is that the 64K upgrade is very, very easy to do - 2 RAM chips and a few pieces of wire. Quote Link to comment Share on other sites More sharing options...
Paul Westphal Posted December 3, 2014 Share Posted December 3, 2014 If you can solder, the ram upgrade is easy. The chips are 4464-100 and can be found at unicorn electronics. I have some as well. Quote Link to comment Share on other sites More sharing options...

Goddy Posted December 3, 2014 Author Share Posted December 3, 2014 Thanks for the help That mod doesn't look to hard to do my soldering skills are ok but I will get some practice in before I try it out I followed a Ebay link from the post that Atari8warz put up for me cheers for that too and I just want to make sure that these are ok to usehttp://www.ebay.com/itm/TI-TMS4464-10NL-DIP-18-x4-Page-Mode-DRAM/271387430539?_trksid=p2047675.c100011.m1850&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D27538%26meid%3De12867072746431c8cc51f61ac1e96a4%26pid%3D100011%26prg%3D11353%26rk%3D1%26rkt%3D10%26sd%3D261078481809 Quote Link to comment Share on other sites More sharing options...
atari8warez Posted December 3, 2014 Share Posted December 3, 2014 (edited) Yes, they're good. My originals were TMS4416-15 (150ms), these are 100ms so they will be just fine. Just remember it will take nearly a month (sometimes even more) to get'em from HK or CN and reading vendor's eBay feedback carefully always helps. Also, I checked this particular listing and seen they charge shipping and still have a long handling time, you may want to find a listing with free shipping so that if the chips are bad you can get a full refund. Lot of people from CN and HK ship free with the same shipping time. Just a point to consider. Edited December 3, 2014 by atari8warez Quote Link to comment Share on other sites More sharing options...
+orpheuswaking Posted December 4, 2014 Share Posted December 4, 2014 I would crack it open and take a look, it may already have the upgrade in it if it came with a SIO2SD. Quote Link to comment Share on other sites More sharing options...

He doesn't have to crack it open to see if it has a RAM upgrade, if the output of "? FRE(0)" in BASIC is 37902 then it has 64K. 1 Quote Link to comment Share on other sites More sharing options...
Goddy Posted December 4, 2014 Author Share Posted December 4, 2014 I done a memory test on it by typing bye then return on the basic screen when I powered it up pays to read the manual it does only have 16k I guess the person I bought it off just gave up on it he did tell me it was only a 16k machine Quote Link to comment Share on other sites More sharing options...
gilsaluki Posted December 6, 2014 Share Posted December 6, 2014 Super easy to upgrade, and cheap. I did two of them recently by following directions here. Memory chips are available cheap on Ebay. Quote Link to comment Share on other sites More sharing options...

Indeed, but where is the fun in that Quote Link to comment Share on other sites More sharing options...
