I recently bought an XEGS with the intention of using it hooked up to my PC with a SIO2PC cable. I've gotten APE working and have tested a couple of bootable floppy images so I know it's working. But, when I start to tinker with DOS I'm lost. What version(s)/type(s) of DOS should I look for? Also, what are the limitations to the programs I can run on the XEGS. Thanks!
