I love the hacked modem idea. But then again, I remember those days, and they were great.
My first computer (I build from parts, way cheaper back then) had two 360k (yes kilobytes) floppies and I ran DR Dos on it. Then I found out about BB'sing... So I added a blazing fast 1200kb internal modem on my "turbo" 4.77MHZ (with turbo 8MHZ) computer. I started making ANSI graphic displays for myself and others using TheDraw. I had so much fun. Nobody was using Windows back then, it was DOS or a *nix variant. I later ran a BBS called "Celestial Odyssey BBS" that ran Searchlight BBS software, I upgraded my storage with 720k floppies and a "huge" 40MG Seagate HD. BTW my first internet experience was with a BBS that had a BSD shell account, telnetting into BBS's became a thing. Lynx was my first browser...
Please excuse my rambling, those where just some awesome times... Go for it Wendell.
