@simonwoods That’s an interesting view of it, thanks! I guess we really are all early adopters here on micro.blog. I was definitely an early adopter in using personal computers for accounting, as I bought two Apple II+ machines in 1979 (NOT cheap), one for my business and another for myself, within months of Visicalc being released. It was truly the killer app. That was two years before IBM put out the first PC. I still have the padded manuals that Visicalc came in, one still unopened in its shrink wrap, with the program disk still in there. Maybe it says something about me that I preserved those manuals, but not the two computers. With a two year lead over IBM, it’s too bad that Apple didn’t manage to build a strong market in the accounting industry, which was quickly overtaken by the PC once it came out, while Apple seemed to stay in the hobbyist market. I’d like to read the story on how they blew that lead. I never thought to ask Andy Hertzfeld whether he knew anything about that. I quickly moved on from Visicalc for most of my work to a full-blown double-entry program written for the Apple II+ by a CPA in Dallas. The tiny 64K RAM was never a problem. I kept separate P&L’s for up to seven different sales locations. It’s basic functionality far out stripped what the PC had until Quickbooks was released for the PC in 1983. So Apple had more like a four year head start on the PC, but they probably didn’t realize it. I’ve often wondered whether that CPA sold his software and it became the foundation for Quickbooks. I talked with him on the phone at the time, he was easily accessible, and he knew his software was brilliant!
