Wow. 2400 baud.
My setup, we used a Novell Network, those early multi-tasking programs were not stable for multiple lines/multiple door game users...just not enough memory to go around. So, we had the dedicated Novell Server, then each Node Machine merely had a 386 SX 25mhz in it with 4mb of RAM. No hard drives, just a floppy drive, modem and Network card. Booted up, logged into Novell and took calls. Worked really well despite the additional cost(s)
Also recall the "big day" I went from 4 2400 modems to 4 14,400 baud modems. InfoTel modems, full length cards. Still got em, monsters!
Then, Zoom had a Sysop Program where if your login message said "Connected to a Zoom Telephonics Modem at ", they'd sell you modems for over 1/2 off! So, that's how we upgraded to 28.8 cheaply.
But when the Internet rolled around, I pondered offering dialup Internet like others were. I opted to stay a content-provider and yanked the modems when it was down to only 20 calls a day (down from a high of 300+). So, I don't care who people connect to the Internet with, as long as they find me via HTTP/Telnet etc
Oh man, just remembered, I also had Planet Connect back then...satellite feed...Fidonet messages, weather forecasts, and lots of new shareware files. At a blazing downlink speed of 19,200.
How about Door Games? I know the biggies on my system were games like...
TradeWars 2002
Food Fight
Legend of the Red Dragon
Solar Realms Elite
Baroon Realms Elite
etc etc
BBSs are trying to make a come back, its just a squeak trying to persuade the hardliners to give it up on ANSI and embrace HTML. I see a lot more web browsers than Telnet clients at all the Internet Cafes I visit!
