Hi,

Just acquired a 1200XL recently and replaced it`s original ROM with the 800XL ROM. After that my MyIDE+Flash cart have stoped complaining of it`s rom.
What are the best solution to get it compatible with most stuff? Internal MyIDE would do the trick? Or I need also the Warp+ OS solution?

Thanks!
Daniel

You could do the internal BASIC upgrade.
Read this: http://www.atarimax.com/myide_old/docum ... 200xl.html for reference.
You can pop the BASIC-eprom in the TOP socket and the OS in the bottom.
Need to change the MMU.....

MyBIOS in ROM would be the best option.

Update your MyIDE to the latest MyBIOS? (What MyBIOS does your boot-screen show?)
