I used to develop applications in COBOL for CP/M microcomputers, then Dataflex and then, for a short time, Turbo Pascal. Some customers ran inventory and accounts receivable applications off floppy disks. Lots of manual data entry too.

What hardware did they typically use?

  4 MHz Z 80A CPU, 64 KB RAM, 2 5 1/4 floppy disks (and later, 5 MB hard disks), serial printers. http://www.mci.org.br/micro/prologica/s700.html http://www.mci.org.br/micro/prologica/s700.html http://www.mci.org.br/micro/prologica/s700_ms_1g.jpg http://www.mci.org.br/micro/prologica/s700_ms_1g.jpg

I used to develop apps in dBase II on CP/M back in the early to mid 80's. We used to have these lovely NEC computers (PC 8800 and APC) with dual 8" and 5.25" drives running CP/M. Later the boss bought me a Torch Z80 [0] co-processor, which ran a clone of CP/M called CPN, for my BBC Micro so I could fiddle about and work from home. We used to use WordStar as our code editor and would patch its printer drivers by hand to get them working with certain NEC and Juki printers. Then once day we bought an early PC clone (a Ferranti box) and things moved on. Amazingly some semblance of Torch is still around [1] [0]: https://en.wikipedia.org/wiki/Torch_Computers https://en.wikipedia.org/wiki/Torch_Computers [1]: http://www.torchcomputers.co.uk/ http://www.torchcomputers.co.uk/

DataFlex :) it's still around, but nowadays it supports less platforms. There's still a unix/linux version (3.2) but that hasn't been updated in many years. The Windows version however is still going strong -version 18.2- and also supports web. I used to program in dBase and Turbo Pascal around that time, but mostly skipped CP/M and started with that Microsoft clone albeit the IBM version.
