I also completely forgot that Qmodem isn't the protocol but the software. My first PC was an IBM XT 8088 with 20MB HD and 2400 baud modem. Twice as fast as a 1200 baud and the number of floppy disks it could fit in that hard drive!
Now also remembering we could assign macros on Qmodem to function keys. That let us automate playing games like Trade Wars. I'll be honest and say we were using it to also pirate games like Space Quest, Ultima, Leisure Suit Larry.
My lord, where has the time gone since then?
