However, #3 and #4 are clearly different OS versions, yet both claim to come from the 130XE. The first two seem fairly unambiguous as the Kernels for the 600XL and 800XL respectively. 03 (130XE - PAL) - CRC=CBED0B4CĪtari XL-XE OS REV. However, I have since then come across four different ROM files for the different machines that I believe are ripped untouched from legitimate chips. Basically I have been told they are practically identical and not to worry about it. In the past I have asked several of the 'old hands' here what the difference is between the XL and XE OS Kernels. I also think it may well be interesting to others than just me. I think it is important enough to have its own thread and maybe get some attention it would otherwise have missed.

So bearing that in mind, remember that this is one of those 'enter at your own risk' kind of projects, requiring a high proficiency in electronic soldering, assembly and troubleshooting.I asked this question as an aside during a different thread.

Anything ranging from a missed solder joint, solder bridge, or a bad or marginal chip can totally derail operation of the board. Last but not least when it comes to DIY, please keep in mind that there are numerous variables that could easily factor into whether your board works or not on first boot.

I recommend that this be flashed to the 1088XEL's U1MB in order to enjoy the full experience ( Firmware). Thanks to AtariAge member flashjazzcat, there is a new build of the U1MB BIOS specific to the 1088XEL. I won't be too involved with this aspect, so please direct any questions you may have about this to MacRorie. Please be sure to use the sub-page links to see some of the additional accessory items that can be built to expand upon the basic system, such as the internal Compact Flash Drive ( XEL-CF3).ĪtariAge member MacRorie is selling individual bare boards, parts kits, fully assembled boards, and full systems at The Brewing Academy website.

This project is now considered fully released, and all of the pertinent files to get started with a DIY build are now available from this page.
