I read a few threads that mentioned there was some work being done porting the XT-IDE over the to the PCjr as a sidecart and adding in 512kb of RAM.
Has there been any progress on that?

The thread is over at my PCjr forum: http://www.brutman.com/forums
Just a quick update - some of the early adopters have the second pass of cards. This is mine running on a machine, but without the IDE BIOS ready yet:

This card has 512KB of SRAM to expand the basic machine from 128KB to 640KB. There is another 512KB of SRAM that can be used for filling memory holes, under software control. The IDE port uses memory mapped registers and a memory mapped sector buffer so it should be 3 to 4x faster than the existing XT-IDE cards when doing data transfers from the storage device. There is also a Dallas RTC and a POST port display. Connection options include 44 pin and 40 pin IDE connectors.
A great job by EEguru ...
Mike to work on the PC-DOS 5.x patch so I can run 8088 Corruption on the ole Jr and upload the video to youtube.com! Apparently PC-DOS 3.3 isn't supported. It keeps complaining the file I specified isn't found. QQ
