Hardware, Networking, and Modems

  • Debate on how the machines were networked: suggestions include coax (10base2 or Arcnet), Novell NetWare over NIC ROM/network-boot, and phone-cable-based IBM networking; exact setup is unclear.
  • Visible external modems are mostly identified as US Robotics Couriers; counts suggest roughly one or two modems per PC, with no clear evidence of internal modems.
  • Some recall specialized multi-port serial cards (Digi, RocketPort, BOCABoard) and breakout boxes enabling 8–128+ serial ports on a single machine.
  • Higher-res images show 66-blocks likely breaking out dozens of analog lines, consistent with large numbers of dial‑in nodes.

Multi-line Capability and Software/OS

  • Several participants dispute the idea that DOS BBSes were “one modem per box.”
  • Examples given of:
    • Multi-line BBSes on DOS (PCBoard, MajorBBS, Searchlight) using DESQview, DoubleDOS, OS/2, or dedicated multi-user BBS software.
    • Apple II and Amiga systems running multiple lines, including Diversi‑Dial and custom multi-user loops.
  • Others point out real limits: IRQ scarcity, I/O throughput, and CPU made very high line counts per PC impractical, pushing operators toward more boxes or intelligent serial hardware.

Scale, Power, and Cooling

  • Discussion on power: individual 286/AT-era PCs used far less CPU power than modern desktops, but room heat from many boxes and modems was still significant.
  • Some argue a single modern machine (or even a Raspberry Pi) could replace the entire room’s compute, though telco aspects are not directly comparable.
  • Cooling was often rudimentary; early POPs and BBS rooms could be very hot with warped plastic and minimal A/C.

Telco Lines and Infrastructure

  • Large BBSes needed many inbound lines and properly configured hunt groups; getting 25+ residential lines was unusual and could raise suspicion.
  • Evolution mentioned from individual analog modems to PRI, T1, and T3-based digital modem banks and terminal servers (Portmaster, Ascend, Telebit, etc.).

Nostalgia, Culture, and Lessons

  • Strong nostalgia for BBS culture: small local communities, shareware distribution, long-distance bills, phone phreaking, and the “feel” (sound, smell, camaraderie).
  • Some romanticize the hardware sprawl; others emphasize the operational pain and use this as a cautionary tale about scaling with more machines vs. better software.
  • Comparisons are drawn to today’s forums, Discord, microservices, and the algorithm-driven, engagement-maximized web, with some lamenting the loss of higher signal-to-noise, non-ad-driven communities.
