Keeping the nostalgia of the 90s alive!
A vintage bulletin board system running on MS-DOS with a bit of a modern connectivity. This system runs on Wildcat! BBS v4.20 released in 1995.
BBS is running 24/7 all year round, accessible in a variety of methods even if you don't have a modem:
Dial-up: 341-221-4808, or 844-227-4979 toll free
US Robotics Courier V.34/V.Everything (up to 33.6k)
Telnet: bbs.tuxedocatbbs.com port 2323 (IPv4 and IPv6 supported)
Web client: www.tuxedocatbbs.com/bbs
Want to use a real dial-up modem? Contrary to popular belief modems do work on VoIP connections even at high-speed 28,000-33,600 bps rates!
If you don't have a land line telephone anymore, you'll need a device known as an "analog telephone adapter" or ATA and an account with a VoIP service. This is basically a small little box that is connected to your Internet connection and provides dialtone to a phone/fax/modem. I personally use Cisco ATA 191, Cisco SPA 112, and Grandstream HT802 adapters and they work very well.
The key thing for ATAs is to use the "G.711" audo codec, which does zero compression, and disable all echo and silence suppression. You will need a stable Internet connection, so probably no wifi tethering, 5G/LTE, nor Starlink.
For a VoIP provider, VOIP.ms is very popular with the vintage community. They offer a use-as-you-go plan where they charge a very low per minute rate and do not charge a monthly fee. Top up an account with $20 and use it for months!
For modems, my testing has shown they're all really about the same. US Robotics Courier and Sportsters are popular, Hayes, Supra work well. There's no need to buy a 56k modem. A 14.4k / V.32bis modem is perfectly fine for calling BBSes. V.34/V.34+ 28.8k/33.6k modems work too.
