I have a 5160 XT and I have spent quite a but of money on it to get it running so I am a bit low on cash right this minuet, however I will be getting more money next month. Anyway I am looking for a good version of dos for my IBM 5160 XT. It has a 20mb hard drive and 640kb of ram. and I believe it has a 8088 cpu. I am also interested in learning Qbasic so it would be nice to have a version of dos that includes qbasic in it such as (MS-DOS 5.0 and higher) and (PC-DOS 5.x according tohttp://en.wikipedia.org/wiki/QBasic) so if anyone is willing to sell me a version of dos that includes qbasic for a good price that would be great.
