La Cueva BBS in Mexico in 1993 (session replay)
2 hours ago
- The main computer in 1993 was a homebrew Z280-based system with 512 KB RAM, VGA card, floppy drive, and serial/printer ports.
- A discarded Hayes modem at 2400 baud was used, requiring a custom serial terminal program written from scratch.
- RS-232C, AT commands, and ANSI escape sequences were learned from books, leading to minor discrepancies that were resolved via a capture buffer.
- A 64K capture buffer saved a session on La Cueva BBS on February 11, 1993, preserving displayed data but not keystroke timing.
- The BBS era ended around 1994–1995, with La Cueva and others disappearing; a JavaScript replay was created from the captured file.
- The replay uses jsTerm adapted for 2400 baud, requiring CORS header modifications for the font, and additional captures like Nopal BBS were later added.
