I am still in contact with some of the programmers who developed System Builder , SB and SB+ , I'll see if they can assist with your request.
Many moons ago I used the original System Builder before SB and SB+ were born. Speaking of born, my first Pick job was with a company in Johannesburg South Africa which was about a mile or 2 from where System Builder was born. The company was called Computermatic . Neill and Derek Miller started it I believe. See Neill's LinkedIn link below. In case you don't have access, I copied some of the relevant info. from his profile.
"My first startup Computermatic a computer services bureau, which I started with one partner and one programmer in 1972 was listed on the JSE (Johannesburg Stock Exchange) in 1985.
I also facilitated several mergers and acquisitions, including companies such as Bell and Howell, Micrographix and Business Land, resulting in 4 listed companies on the JSE.
After immigrating to Australia in 1987, I formed a start up computer software company with my cousin Derek Miller called System Builder Development (SBD) to continue to develop the 4GL System Builder and SB+."
