I didn't do much programming on the #A500 or #A2000HD but when I got the #A3000T, I ran The Heart of Gold #BBS using DLG BBS software and #Fidonet node 1:255/42. I used #AREXX to write apps for the BBS.

Fidonet let you request a list of downloadable files so I wrote an AREXX script to let my BBS users request a list of files and they could come back the next day and browse through it and request files.

Another AREXX script connected to the internet and synchronized a few USENET newsgroups into the DLG message area.

On the A2386 running Slackware Linux, I wrote a simplistic compression program in GNU C that could only compress to a maximum of 25%. I'd like to have that code again too.
