La Cueva BBS in Mexico in 1993 (session replay)

Óscar Toledo G. recalls his 1993 Zilog Z280-based homebrew computer with 512 KB of RAM, a Hayes modem running at 2400 bauds, and a self-written serial terminal. Without the Internet, he learned RS-232C, AT commands, and ANSI escape sequences from books. He implemented escape sequences like Esc [2J and Esc [0;35m, but book definitions sometimes differed from real BBS usage.

To handle deviations, he added a capture buffer using the Z280's 64K MMU access, saving every received byte sequentially. A file named CUEVA.TXT on an old floppy disk preserves a session from 9:30pm to 9:47pm, after February 11, 1993, while calling La Cueva BBS in Mexico. The replay shows a file download attempt, phone line failure trash, and buffer overflow starting with a log off message.

Keystroke timing was lost, so screens change rapidly. Other BBS of the era included Catarsys, and La Cueva BBS likely disappeared by 1994 or 1995. The replay uses Javascript code and an adapted js Term by Peter Nitsch, with .htaccess changes to un-taint the canvas font.

Óscar Toledo G. found a 1993 list of BBS phone numbers displayed as an alternate help page, with passwords redacted. Watching the replay brought back memories, and some friends had no idea the BBS existed.

Óscar Toledo G. recuerda su computadora casera de 1993 basada en Zilog Z280 con 512 KB de RAM, un módem Hayes que funcionaba a 2400 baudios y un terminal serie escrito por él mismo. Sin Internet, aprendió RS-232C, comandos AT y secuencias de escape ANSI de libros. Implementó secuencias de escape como Esc [2J y Esc [0;35m, pero las definiciones de los libros a veces diferían del uso real en los BBS.

Para manejar las desviaciones, añadió un búfer de captura usando el acceso MMU de 64K del Z280, guardando cada byte recibido secuencialmente. Un archivo llamado CUEVA.TXT en un disquete antiguo preserva una sesión desde las 9:30 p.m. hasta las 9:47 p.m., después del 11 de febrero de 1993, mientras llamaba a La Cueva BBS en México. La reproducción muestra un intento de descarga de archivo, basura por falla de línea telefónica y desbordamiento de búfer que comienza con un mensaje de cierre de sesión.

Se perdió el timing de las pulsaciones de tecla, por lo que las pantallas cambian rápidamente. Otros BBS de la época incluían Catarsys, y La Cueva BBS probablemente desapareció en 1994 o 1995. La reproducción usa código de Javascript y un js Term adaptado por Peter Nitsch, con cambios en .htaccess para limpiar la fuente del lienzo.

Óscar Toledo G. encontró una lista de 1993 de números de teléfono de BBS mostrada como una página de ayuda alternativa, con contraseñas redactadas. Ver la reproducción le trajo recuerdos, y algunos amigos no tenían idea de que el BBS existiera.

Óscar Toledo G. rappelle son ordinateur maison de 1993 basé sur Zilog Z280 avec 512 Ko de RAM, un modem Hayes fonctionnant à 2400 bauds et un terminal série écrit par lui-même. Sans Internet, il a appris le RS-232C, les commandes AT et les séquences d'échappement ANSI à partir de livres. Il a mis en œuvre des séquences d'échappement comme Esc [2J et Esc [0;35m, mais les définitions des livres différaient parfois de l'utilisation réelle des BBS.

Pour gérer les écarts, il a ajouté une mémoire tampon de capture en utilisant l'accès MMU de 64K du Z280, en enregistrant séquentiellement chaque octet reçu. Un fichier nommé CUEVA.TXT sur une vieille disquette préserve une session de 21h30 à 21h47, après le 11 février 1993, lors de l'appel à La Cueva BBS au Mexique. La relecture montre une tentative de téléchargement de fichier, des déchets dus à une panne de ligne téléphonique et un débordement de mémoire tampon commençant par un message de déconnexion.

Le timing des frappes de touche a été perdu, donc les écrans changent rapidement. Autres BBS de l'époque incluaient Catarsys, et La Cueva BBS a probablement disparu en 1994 ou 1995. La relecture utilise du code Javascript et un js Term adapté par Peter Nitsch, avec des modifications dans .htaccess pour nettoyer la police du canevas.

Óscar Toledo G. a trouvé une liste de 1993 des numéros de téléphone des BBS affichée comme une page d'aide alternative, avec les mots de passe masqués. Regarder la relecture a ravivé des souvenirs, et certains amis n'avaient aucune idée de l'existence du BBS.
