I have an original copy of Microsoft BASIC-80 (c) 1979, Release 5.1. It is for Heath/Zenith systems, but really that part of it is just an insert at the start of the manual. The rest of the manual is generic and applicable to all BASIC-80 versions. Before spending the time to scan it, is this online anywhere already? I did a google search on BASIC-80 manual but didn't find any hits in the first few pages. Likewise, I have an original manual for a similar vintage MS BASCOM (basic compiler). Thanks.
