In the late 80's, Apple came out with HyperCard. I was on active duty with the United States Air Force. Due to my association with Apple at the time, which included being the primary network administrator for a Macintosh "test" network for the Military Airlift Command (MAC!) staff that included speech writers and others on Scott AFB, Illinois, I began to "play" with the $49 software both on duty and off.
The local Apple store had a strong client base (small newspapers) that which they sold Apple hardware. It needed a targeted software application that could be used with a minimum of training and effort to input and format classifieds ads. It needed to include both the input and formatting capability that allowed the output to be exported directly to a page layout application for printing (like Aldus Pagemaker).
Upon receiving the Handbook and Developer's Guide, I decided to tackle the project.
It was fun.
I found the scripting language easy to follow and started to "program" the application small rural newspapers needed. I lost track of how many lines of "code" it took to create the finished app, but it was a lot!
I called my "stacks" - Classifieds! - and my DBA "PersonalVision". As I retired from the USAF in 1993, the local computer store hired me to visit their clients and demo and install Classifieds!. I also provided support both on my corded phone (remember, pre-internet times) and in person. I remember driving to and from several newspapers in Iowa in driving snowstorms.
The one limitation of Hypercard was that it could not interact with the burgeoning "Internet" at the time, and was replaced by superior database applications that worked better with the newer Apple Macintosh computers that were being released.
Steve Jobs disliked the software because Bill Atkinson (HyperCard creator) had chosen to stay at Apple to finish it instead of joining Jobs at NeXT, and (according to Atkinson) "it had Sculley's stink all over it".
Classifieds! faded into history.
