I have just gotten 5 copies of IBM Disk Operating System Version 3.30 with 2-5.25" 360k and 1-3.5" 720k disks included. These are like brand new, never opened. Asking $6.50 per unit, plus $5 priority mailing in the lower 48 US states. AK and HI as well as APO/FPO may be more, will have to see on a case by case basis. First come, first served. Money orders only, please! I bought the box of 6 sets to get one copy for myself at $40.00 and $6.50 is about what each copy cost me, so I won't make any money at all on this. I know there are those that would love to have this for that classic, or to have with other verions of DOS. These are the small format manuals, not the encased notebooks so you don't have to worry about pages getting torn out later. I have calculated shipping from me to California, Chicago, NYC and Tampa to come up with a rate that is within a few cents of actual, hence the $5.00 shipping. All of the locations yielded a $5.40 priority mailing and regular rate is real close to that. If you want a copy email me directly at RHBLAKE(a)BIGFOOT.COM so I can give you a mailing address for payment. Not sure of my reputation? Many of you have bought and traded with me on eBay and on the lists so my reputation for delivering what I post preceeds me. I'm not doing this to get rich, just to fulfill my own nasty habit and spread the wealth among other with the same "disease".
