IBM-branded Microsoft Assembler (MASM); DOS 3.3 Stuff.

As I understand it, there were IBM-branded versions of the Microsoft Macro Assembler(MASM) prior to version 4. I seem to recall seeing one way back when, in the usual small IBM binder in a slip cover box. What version(s), if any, would have been roughly contemporary with IBM DOS 3.3? Did the MASM version numbers track with DOS releases, or were they independent? I think that I would like to get my hands on one of these. An original copy would be preferable; scans and images would be helpful if I can't find an original. I have an original IBM DOS 3.3 distribution, still in shrink wrap. I understand that some developer-oriented tools were removed from the 3.3 distribution, and instead came on a utilities diskette with the DOS 3.30 Technical Reference. I see a listing for the book on eBay which I may buy, but it doesn't include the diskettes. If originals or images of the diskettes are available, I'd like to acquire them. Were there any other IBM-branded development tools for the PC around the time of DOS 3.3? -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/
