rockdoc2010 Posted January 16, 2015 Share Posted January 16, 2015 I am wondering if the Atari 1064 64K "cartridge" will be compatible with the 64K 2 chip mod that i have successfully installed? 128K? thanks Douglas Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted January 16, 2015 Share Posted January 16, 2015 No. It'll just be used instead of the on-board RAM. Quote Link to comment Share on other sites More sharing options...
Almost Rice Posted January 16, 2015 Share Posted January 16, 2015 You are better off seeing if you can get Ram 320XL upgrade from ctirad. It should cost about the same as a 1064. It is the best way to u/g a 600xl. Quote Link to comment Share on other sites More sharing options...
kogden Posted January 16, 2015 Share Posted January 16, 2015 Max RAM supported by any 6502 is 64KB. It only has a 16-bit address bus. The only way to get beyond that is by "cheating" and swapping 16K chunks of RAM in and out of address space with bankswitching and the 1064 doesn't work this way. There's several ways to get some extended RAM though. -Best sells an internal 256K (64K Base, 192K extended) upgrade that isn't too terribly tough to install. -There's also the RAM 320XL which is solderless and plugs in like the 1064. These are kinda hard to find right now. -And of course there's stuff like Ultimate 1MB and the MegaHz 512K expansion. The MegaHz upgrade is tough to install in a 600XL.

+CharlieChaplin Posted January 16, 2015 Share Posted January 16, 2015 Well, stay tuned - there will be a RAM 576XL soon by ctirad and it is as simple to install as the 1064. Just plug it into the PBI... Quote Link to comment Share on other sites More sharing options...

It may or may not work properly. Best not to do it. James Quote Link to comment Share on other sites More sharing options...
