Dopeyman06 Posted July 4, 2023 Share Posted July 4, 2023 So I just recently acquired this 1200XL. And I noticed that it's already been modified with a 28 pin socket and some eproms. Can someone give me some info on what it's been changed to? Also, this machine has the problematic keyboard malfunction and is missing the "2" key. Can someone point me in the right direction on getting that key? Quote Link to comment Share on other sites More sharing options...

And I noticed that it's already been modified with a 28 pin socket and some eproms Those are factory EPROMS in an early production machine. And some machines came from the factory with 28-pin sockets even if they were equipped with mask ROMs. Two of my 1200XLs came that way - mask ROM chips in 28 pin sockets. That was convenient when I put an Ultimate 1MB in one of them, and when I put the later 1200XL rev 11 OS EPROMs into the second one. 1 Quote Link to comment Share on other sites More sharing options...

I've seen posts here and there regarding that rev11 and 32-1 and all those other mods. But what if I just want a plain 1200XL with just Basic rev.C installed?? No other fancy OS's. How can I go about it? Quote Link to comment Share on other sites More sharing options...
Rybags Posted July 4, 2023 Share Posted July 4, 2023 Likely it's the stock 1200XL OS. Boot without a disk drive or type BYE from Basic to see if you get the logo or Self-Test. 1 Quote Link to comment Share on other sites More sharing options...

And I can't type BYE with the BASIC cart (rev.B) cause the B key doesn't work LOL! I'm interested in modding this 1200XL with Atari BASIC (rev.C) built in. None of those other fancy-shmancy OS's. I've already fixed the SIO port (5+ volts) and added 256k RAM (MyTek's RamboXL Clone). Edited July 4, 2023 by Dopeyman06 Quote Link to comment Share on other sites More sharing options...

I have a parts keyboard and will see if it's the same type. 1 Quote Link to comment Share on other sites More sharing options...
+kheller2 Posted July 4, 2023 Share Posted July 4, 2023 You can split and burn the 800XL OS to two EPROMs and go with that. If you really want internal BASIC you’ll need to burn BASIC C, a 16K 800XL OS and you’ll need the MMU from same. 1 Quote Link to comment Share on other sites More sharing options...
DrVenkman Posted July 4, 2023 Share Posted July 4, 2023 If you want to put in internal BASIC, follow the first part of these instructions. http://retrobits.net/atari/pbi.shtml 1 Quote Link to comment Share on other sites More sharing options...

If you boot without a DOS, you can also type "DOS" from BASIC and get the same result as typing "BYE". Quote Link to comment Share on other sites More sharing options...
AtariGeezer Posted July 4, 2023 Share Posted July 4, 2023 @Dopeyman06 Ok, found one (if all 1200xl keyboards are the same) I'll send it out in a few days Send me a PM with your address. Jay 2 Quote Link to comment Share on other sites More sharing options...

I've watched YouTube videos and other websites. I'm still not sure if I should do it myself or send it out to get fixed. Quote Link to comment Share on other sites More sharing options...
+bf2k+ Posted July 5, 2023 Share Posted July 5, 2023 I just cleaned my 1200XL keyboard and it worked for a few years until I sold it last year. 1 Quote Link to comment Share on other sites More sharing options...
wildstar87 Posted July 6, 2023 Share Posted July 6, 2023 I think you are going to need a replacement key stem as well, the one on your keyboard looks broken, probably why the 2 is missing. 1 Quote Link to comment Share on other sites More sharing options...

Yeah. Looks like you're right. The stem does look like it's broken. Quote Link to comment Share on other sites More sharing options...
