badbrad Posted April 8, 2006 Share Posted April 8, 2006 I'd like to upgrade my 400 to 64K. Can somebody point me in the right direction? Maybe somebody here even has the parts. Quote Link to comment Share on other sites More sharing options...

I dont know who has a current upgrade for a 400, but you might consider talking to warerat and see if he will modify his 800 upgrade for you. He has upgraded 800s to 32k OS boards and XL OS. It might cost you a pretty penny though and you would lose joystick ports 3&4. I would advise you to get a 800 and warerat's OS. This has a real keyboard and leaves your 400 in prestine condition.

+Guitarman Posted April 8, 2006 Share Posted April 8, 2006 I'd like to upgrade my 400 to 64K. Can somebody point me in the right direction? Maybe somebody here even has the parts. B&C sells the original Atari memory upgrade for the 400. It is listed as a 48k upgrade but the board itself says 64k. I'm sure part of it is reserved memory. I have it installed in mine and it works great. From B&C's site: ACA020 MEMORY 48K UPGRADE 400 14.95 Quote Link to comment Share on other sites More sharing options...
badbrad Posted April 8, 2006 Author Share Posted April 8, 2006 My whole issue is this. I would like to play Shamus II while retaining my ability to play the other Synapse carts. Is there a workaround on the 800XL to play the old Synapse carts reliably? Quote Link to comment Share on other sites More sharing options...

I'm saying that the XL has an issue playing Synapse carts. And yes, I do have an 800XL. Quote Link to comment Share on other sites More sharing options...

I think he is the one that sells APE Warp+ for XL/XE computers. That is the multi OS that should allow you to use the 800xl with 400/800 OS. Alternatively you could buy one of his 1Mbit or 8Mbit carts. Then load up XL/XE fixed versions of the game onto those carts.

badbrad Posted April 9, 2006 Author Share Posted April 9, 2006 Well, I'm kind of a purist when it comes to carts. I have the carts, I like to plug them in and play. I guess I'll just have to set up both systems in the meantime. Quote Link to comment Share on other sites More sharing options...
walter_J64bit Posted April 9, 2006 Share Posted April 9, 2006 I recall back in the day there was a 64k upgrade for the 400 but the 400 couldn't run any XL/XE programs. Quote Link to comment Share on other sites More sharing options...
Rybags Posted April 9, 2006 Share Posted April 9, 2006 Does the Translator allow you to plug in carts? If not, it would be fairly simple to either modify it, or just modify an 800 OS to be RAM-resident on the XL and allow it. Quote Link to comment Share on other sites More sharing options...
