Open Source redux

While I don’t update here much anymore that’s mostly because I’ve not been active in the general technology scene for the last 2.5 years following my departure from Dell and the resultant non-compete. I’m taking a few easy steps back now, I’ve reactivated my British Computer Society (BCS) Fellow membership and am hoping to participate in their Open Source Specialist Group meeting and AGM on October 25th.

MS-DOS Open Source

msdos-logo-150x150[1]Interestingly, Microsoft have announced they are re-open sourcing the code for MS-DOS 1.25 and 2.0 releases. Although never available outside of Microsoft or IBM in its entirety, there were certainly sections o the code floating around in the mid-1980’s. I was given the code for some drivers in 1984 by an IBM Systems Engineer, which I proceeded to hack and use as a starter for the 3270 driver I used for file transfer.

I’ve got a copy of the code released by Microsoft, and other the next 6-months am going to set about compiling it and working to get to work on a PC as a way to re-introduce myself to working in PC Assembler and the current state of compilers.
