One of the first programs that I developed for the macintosh in 1986 was a sytek port configurator. It had the ability to display and configure multiple sytek ports via the sytek network.
The Fat Mac was upgraded to a Mac Plus in 1986:
A very large program I did for the Macintosh in 1988 was a C decompiler. It had the ability to look at CODE segments of a program and generate C language of that program. This was nice for a programmer because you could see examples of how someone else coded a particular thing that you needed to write.
This hardware replaced the Mac Plus in April of 1989:
In April of 1990 I did an XFCN for HyperCard that allows the user to set the mac's alarm. This was used in a Calendar stack that I did to keep track of and awake me when it's time to go to meetings.
Also in April of 1990 I did some XFCNs to do AppleTalk's ATP protocol in a client/server arrangement. This was done to do the VCO stack with a server on unix (menudo). VCO is a macintosh Voice COnferencing stack based on Harry Chesley's serial VCO program.
This hardware replaced the IIx in March of 1994:
This hardware was purchased by me for my personal use in January of 1996:
