This rewrites what-could-have-been history a bit... better get my IBM XT/286 out of storage! Is this for real?

I might have to try it out. I have an 8088 IBM PC (my first computer) on a desk. I need to swap out some bad RAM (I've been getting Parity errors and other strange behavior), but it says it works with 256KB so I could remove the AST SixPakPlus altogether. The fully populated mother board has 256KB. (I could also unplug the MFM hard drive controller as well.) It supports CGA and VGA and I have both (the CGA is original; the VGA is an 8-bit ISA one I picked up a couple years ago). I also have a serial mouse... Right now I have one floppy disk that came with a book I re-bought recently (Peter Norton's Guide to Assembly Language) and I could back up the files from it and use that but I think I'd rather buy/find another one to use. And I need more than one disk for this anyway.

Interesting, it currently says, 'Nobody has yet written the images to 5.25" media and booted an actual XT with them.'
